The Meme of Promiscuity and Pair Bonding

A meme in male dating spaces is the claim that promiscuity harms the ability of women to form pair bonds. Put another way, the meme says having many sexual partners will make a woman less able to form monogamous relationships.

In this article I will examine the meme’s loose origin in prairie vole research, as well as its limitations and generalizability to human beings. I will cover the current research on genetic contributions to pair bonding behavior, personality contributions and the heritability of both. I will also look at relationship outcomes and the relationships between promiscuity, infidelity and divorce.

What is a pair bond?

What does it mean to form a pair bond? The prairie vole, a small rodent, mates for life. This animal forms a relationship with a partner that lasts after mating. It cohabitates and raises its offspring together. Only very rarely is the vole sexually unfaithful. If its partner dies the vole might never take a new mate after the death of its partner, instead becoming depressed and lethargic. Separated from their partners in clinical settings, prairie voles become so apathetic they will let you drown them in a pool of water without a struggle (Sun et al., 2014).

prairie vole family
Prairie vole. What the ideal monogamous relationship looks like.

This probably doesn’t remind you of humans. The vole is a mammalian exception — fewer than 3% of mammals form this kind of monogamous relationship (Young et al., 1998). Most primates additionally do not form monogamous relationships. In fact, no primates found in nature form lifelong pair bonds.

Human beings occasionally form what appear to be lifelong pair bonds. However, true lifelong pair bonding in humans is rare. Human beings practice serial monogamy. We usually form relationships, break up and then form subsequent new relationships. The normal course of human mating is to repeat this pattern over the lifespan.

We think of pair bonding and marriage as linked. However most marriages, even ones that last, are not the first relationship of the couple. Serial monogamy is still the dominant human mating pattern (Schacht & Kramer, 2019). This does not mean that the desire to have a lifelong partner is unnatural or unreasonable. What it does mean is that if you find a lifelong partner it’s unlikely that they were your first relationship. It also means that it’s unlikely your first love or sexual partner will be your only one.

Most birds are considered to be pair bonding animals, yet most birds only form seasonal bonds. Birds mate, share the care of the egg and young, then find a new partner next season. Thus pair bonding in animal mating is not necessarily a reference to the lifelong pair bonding of the prairie vole.

Yet when people claim that promiscuity harms a woman’s ability to pair bond they are usually referencing the lifelong pair bonding we see in voles. Herein pair bonding is mistakenly linked with lifelong traditional marriage, a cultural practice that has only existed for a small sliver of human history.

This gives us two questions to examine: does promiscuity harm the ability of women to form lifelong pair bonds that are naturally uncommon in human beings, or does promiscuity harm the ability of women to form the serially monogamous pair bonding that is naturally common in humans?

The first question implies a bad premise to begin with, since we should already expect the average human not to form lifelong pair bonds. The lack of a lifelong pair bond does not indicate dysfunction or the inability to pair bond in the first place. It simply reflects how humans behave.

The second question is more reasonable since we’re talking about a natural human behavior that describes most relationship outcomes. If someone is unable to form a series of healthy, serially monogamous relationships over the lifetime this may indicate a problem. For people who desire monogamous relationships for themselves it is a problem de facto.

Cause vs correlation

When we ask if promiscuity harms a woman’s ability to pair bond it implies a causal relationship. Cause-and-effect. The hypothesis is that having sex with mulitple partners comes first and that these actions have an negative effect on pair bonding outcomes.

The “promiscuity harms a woman’s ability to pair bond” meme usually presents the relationship as causal. A common form would be: sex causes neurological changes in the brain (related to oxytocin, dopamine or serotonin) that harm a woman’s ability to form an emotional connection or a relationship.

To be clear outright — no research has demonstrated this kind of causal relationship. This should not be too surprising to anyone familiar with research design. An experiment that could show a causal relationship here is methodologically prohibitive. We can’t assign women to experimental promiscuous and non-promiscuous conditions. We can’t tell a group of women to have sex with many people and a second group to abstain. We can’t enact an experimental design with methodological assignment that is able to show causality.

People select their own level of promiscuity. We choose to sleep with few or many partners.

The best we can do is to observe that choice. We can look at people who are promiscuous and see if promiscuous behavior correlates with poor pair bonding outcomes. We can establish a correlation by observation. We may not be able to establish a direction of the relationship (i.e. that promiscuity came first) nor can we establish cause-and-effect. We can see if promiscuity predicts something like divorce, short relationships, or perhaps even neurological differences in the brain.

This is still very valuable. We don’t need to know that promiscuity damages pair bonding ability on a practical level. It would be sufficient to know that promiscuity predicts poor outcomes in pair bonds, assuming this is the case. Nonetheless, this is a distinct question and not evidence that would support the meme. Poor longitudinal outcomes within pair bonds are not a failure to form pair bonds.

Causality and the limitations of observational methodology in humans

If humans were voles then we could conduct experiments that establish causality. Indeed, we have classic research on pair bonding in voles. The meme that promiscuity harms a woman’s ability to pair bond first became popularized by referencing research on voles.

Almost 30 years ago, Williams et al (1994) removed the ovaries and wombs of voles. His team implanted cerebrospinal pumps that delivered oxytocin and vasopressin to the brain. Voles with hormonal pumps were able to form pair bonds from the administration of exogenous vasopressin and oxytocin.

However, his team noted some fundamental differences between prairie voles and human beings.

Unaltered voles form pair bonds independently of sex. Merely cohabitating for a 24-hour period without sex is sufficient for most voles to form a lifelong pair bond. An even shorter six-hour period of copulation is sufficient for voles to form a pair bond. Voles also mate consecutively, dozens of times over a short period.

Male and female prairie voles also form pair bonds in a very similar fashion, with the same neuroendocrine correlates. Both sexes have a similar cerebro-anatomical layout in areas that respond to oxytocin and vasopressin. “Promiscuity harms a woman’s ability to pair bond” is sometimes given the addendum “but not men’s ability.” However, administration of bonding hormones to the male vole causes similar outcomes in pair bonding. Anything we generalize from the vole to the human should be expected to apply to men and women.

But how far should we generalize from voles to humans? We have seen that the vole pair bonding experience is very different from the human experience. An important finding in vole research has been that experimental manipulations of hormones do not work on the prairie vole’s closest relative, the montane vole (Young et al., 1998). Like human beings, the montane vole does not naturally form lifelong pair bonds. If prairie vole behavior can’t tell us anything about montane vole behavior, should we really expect it to inform us about human pair bonding?

In fact we could go the opposite direction with an interpretation of this research: promiscuity does not have an effect on a woman’s ability to pair bond, given that the montane vole does not respond to vasopressin and oxytocin. Is this a legit conclusion? Clearly not, but it follows the same logic of those who would form simplistic generalizations from prairie vole research.

It would even be shored up by research on vasopressin and oxytocin in human beings. These hormones have not been consistently shown to be associated with human mate pair bonding. When we look at human hormonal correlates to pair bonding, dopamine receptors seem to have a much more significant role than vasopressin and oxytocin. This is not to say that vasopressin has no role, but the results have been mixed. This is covered in the next section.

Heritability of promiscuity and pair bonding outcomes

A large portion of our personality and behavior is heritable. The nature vs nurture debate is dead, at least insofar as the two are presented as opposite positions. Similarly, the blank slate is an outdated paradigm that never generated empirical support. Moving forward we must set aside these nuggets of folk psychology.

The current paradigm is nature and nurture, or person-environment interaction. Person-environment interaction is so ubiquitous in behavioral research that it is now considered axiomatic. Your natural disposition, your genes or your biology, interacts with your environment to produce outcomes in behavior. You are the product of your DNA and your experiences.

In behavioral genetics this manifests as the 50-0-50 rule. This rule is based on a consistent observation across behavioral research: approximately 50% of the variance in behavior is heritable. This is not quite the same as saying 50% of your behavior is genetic, but it’s conceptually close. Not only are you the product of your DNA and your experiences, but you are the product of both in almost equal measures.

Knowing this, it should not surprise you that both promiscuity and relationship outcomes are heritable. The heritability of promiscuity is as close to a fact as we can get with the methodology used to establish it. We see the heritability of promiscuity across animal species and in human beings. The only question is how heritable it is, but not if it is heritable.

We may see low heritability, for example in the generally promiscuous red squirrel (McFarlane et al., 2011) or high heritability, for example in the pair bonding zebra finch (Forstmeier et al., 2011). In human beings the heritability for promiscuity is moderate at around 40% (Cherkas et al., 2004; Zietsch et al. 2014), and as high as 60% for men (Zietsch et al., 2014). Again we see the 50-0-50 rule at play.

Here is a table from Harden’s (2014) review of the literature on the heritability of promiscuous sexual behaviors. The second column gives some measures of promiscuity like risky sexual behavior and number of sexual partners, while the third column tells you the heritability. All of the correlations are moderate, ranging from approximately 30% to 60%. 50-0-50.

Genes associated with human promiscuity have been identified. A vasopressin receptor gene (AVPR1A) predicted promiscuity in women (Cherkas et al. 2004; Zietsch et al., 2014) as well as poor pair bonding outcomes for men (Walum et al., 2008). A dopamine receptor gene (DRD4) has consistently predicted promiscuity in both men and women with no sex differences (Hamer et al., 2002; Ben Zion et al., 2006; Guo & Tong, 2006; Eisenberg et al., 2007; Garcia et al., 2010). The DAT1 dopamine receptor gene has been linked to promiscuity in men, but not in women (Guo et al., 2007).

Heritable personality traits, promiscuity and infidelity

The five-factor, or “Big Five,” personality framework is one of the most widely used and well supported personality models in psychology. The Big Five breaks personality into five broad traits: openness to experience, conscientiousness, extraversion, agreeableness and neuroticism. Research has consistently shown that Big Five traits predict relationship outcomes and sexual behavior, including promiscuity (Schmitt & Shackelford, 2008). High extraversion predicts promiscuity, mate-poaching behavior and low relationship exclusivity. Low conscientiousness and low agreeableness predict greater short-term mating and greater extra-pair (infidelity) mating. We see the 50-0-50 rule at play here again — the heritability of Big Five dimensions range from 40% to 60% (Jang et al., 1996).

Although representing a small percentage of the population, diagnosable Cluster B personality disorders predict both promiscuity and poor relationship outcomes. Borderline personality disorder predicts more frequent casual sexual relationships, greater promiscuity and more impulsive sexual behavior (Sansone & Wiederman, 2009). Primary psychopathy traits also predict mate poaching and low sexual exclusivitiy (Khan et al., 2017). Heritability again follows the 50-0-50 rule, at 46% for borderline personality disorder and 49% for psychopathy (Skoglund et al., 2021; Tuvblad et al., 2014).

Adult attachment theory describes four attachment styles. Approximately 43% of the variance in the fearful or avoidant attachment style, which could be interpreted as a pair bonding impairment, is genetic (Brussoni et al., 2000). The remaining variance is explained by the non-shared environment in childhood.

The Dark Triad describes a cluster of three maladaptive and antisocial personality traits: Narcissism, Machiavellianism and Psychopathy. These traits have heritability estimates ranging from .31 to .72. The Dark Triad also predicts promiscuity and infidelity in men and women (Alavi et al., 2018; Burtăverdea et al., 2021).

The Big Five, Cluster B disorders, attachment theory and the Dark Triad are just some examples from popular and widely researched personality constructs. The full list of personality correlates to relationship outcomes could fill many articles by itself. It is, itself, an entire domain in personality psychology. The point is that both promiscuity and pair bonding are largely determined well before a person’s first sexual encounter. Approximately half of the variance is genetic, while the remaining half is formed from early nonshared experiences.

Promiscuity, divorce and poor pair bond outcomes

Up to this point we have examined what explains promiscuity. We have seen that promiscuous behavior is heritable and genetic. We have also seen that heritable personality traits explain promiscuity. The question remains: is promiscuity actually bad for pair bonding?

More specifically, we will look at two separate issues: does promiscuity prevent the formation of monogamous relationships or pair bonds, and/or does promiscuity predict undesirable outcomes once a pair bond has been formed. Only the former would support the pair bond meme, but the latter is still relevant to relationships in general.

Polymorphisms of the AVPR1A vasopressin receptor gene, noted above in a study by Walum et al. (2008), predict poor relationship outcomes for men. Men with this polymorphism score lower on the Partner Bonding Scale. Men who have this also are more likely to have experienced marital crisis and divorce, while women married to men who carry this polymorphism are more likely to report being unsatisfied with their partner (Walum & Westberg, 2011).

A recent pre-published study by Wolfinger & Perry (2021) is the first to test if promiscuity predicts marriage using two longitudinal, nationally representative datasets. In a preliminary study, they found that number of sexual partners predicted a lower liklihood of marriage for women. In a follow-up using the full sample of men and women, they found that the recent number of sexual partners, but not lifetime sexual partners, predicted a lower liklihood of getting married. Promiscuity did not impact the odds of marriage in the long term, so the authors concluded: “Our findings cast doubt on the premises supporting the controversial notion that more readily available sexual activity with numerous partners will reduce men’s and women’s desire or desirability, and ultimately, likelihood of marrying.”

The ability to form a relationship that lasts long enough to get married is a good indicator of pair bonding, particularly when we remember that humans are serially monogamous. At the very least we must concede that a pair bond has been formed. The authors are correct to interpret the results as showing that “sexual activity of single women does not appear to make them “undesirable” as marriage partners” and that “our analyses suggest that this does not manifest itself in long-term singleness.”

Nonetheless we must also consider relationship outcomes, such as relationship duration or divorce. We might also consider relationship quality — the “bond” in the pair bond — as well as infidelity. Wolfinger & Perry (2021) additionally review the research showing that, yes, men and women with more sexual partners are indeed more likely to divorce and more likely to report lower relationship happiness (citing Kahn and London 1991; Kelly and Conley 1987; Larson and Holman 1994; Janus and Janus 1993; Kahn and London 1991; Teachman 2003). 

Khan & London (1991) used a bivariate probit model, which can be described as a quasi experimental methodology, intended to estimate the probability of the outcome of a correlation being due either to a causal effect of a given variable or to another variable. While they found that virgins were less likely to divorce than non-virgins, the probit model showed that when third variables accounting for divorce were included, there was no longer a difference in divorce rates between virgins and non-virgins.

This is another piece of evidence indicating that sex is not a cause of poor pair bonding outcomes, but that pair bonding outcomes are a predisposition. Women more likely to get divorced were also more likely to have premarital sex, but premarital sex was not the cause of divorce.

Promiscuity and infidelity

Past sexual history and number of sexual partners predicts future infidelity in a relationship (Pinto, 2015; McNulty et al., 2018; Treas et al., 2000). The more partners one has had, the more likely one is to cheat. This applies to both men and women. This association is cited as evidence for the pair-bonding meme. 

Does infidelity really indicate the absence of a pair bond? In animals, no. Birds that form pair bonds have a very high rate of extra-pair parenting — about 20% (Wang et al., 2021). This means that 20% of male birds are raising offspring that are not their own, or that 20% of female birds “cheated.” We regularly see infidelity in pair bonding animals. Humans in contrast only have an extra-pair rate of about 3-4%. We are remarkably faithful when compared to other pair bonding animals.

Indeed, infidelity almost by definition only occurs in the context of a pair bond. You can’t cheat on a partner if you are not in a relationship.

This does not mean we should dismiss the association between promiscuity and infidelity. It may be a misunderstanding of what pair bonding is to believe that infidelity nullifies pair bonds, but infidelity is still an undesirable relationship outcome. Framing infidelity as damaged pair bonding is pseudoscientific, but this does not mean it is unreasonable to want a partner who is unlikely to cheat on you.

A hypothetical mechanism of pair bond impairment

The male dating communities that have memed “promiscuity damages a woman’s ability to pair bond” into existence consist mostly of men who struggle to form relationships and men who are not having very much sex. Sex for these men is scarce. They believe that a strong emotional connection is made during intercourse in part because they lack both the emotional connection and sexual regularity of a relationship.

Rather, most people naturally abstain from sex with people they don’t already have a pair bond with. People who are highly promiscuous fail to make these emotional connections from the beginning. The recent 2021 GSS data on sexual partner count that I have run shows that a super-majority of both men and women are not very promiscuous. Additionally, the GSS data shows that most sex occurs in relationships. Just like we have seen how “promiscuity damages pair bonding” is backwards — the evidence points to a predisposition to promiscuity preceding pair bonding outcomes — the emotional and chemical connection made in a relationship does not come from sex, but also precedes it.

Men with little sexual and dating experience also don’t realize how bad sex is for many women. Most women don’t even have orgasms during casual sex. Only 11% of women report having an orgasm during a casual sexual event with one partner, while 67% of women in relationships report orgasms (Armstrong et al., 2021).

how often orgasms during casual sex for women
A minority of women have orgasms during casual sex. From Armstrong et al., 2012.

The belief that women develop a bond with a one-night-stand who couldn’t even make them cum can only come from the perspective of a man completely on the outside looking in. As men we will have good experiences in most of our sexual encounters. For women that is not the case.

It would be more reasonable to believe that a woman’s pair bonding ability has been damaged by being in a single, high-quality and long-term relationship. Imagine a woman who committed to a man, built an actual emotional connection and who developed a satisfying sexual relationship. The bonding hormones released by the female orgasm were triggered repeatedly, over and over, by one man. At least 52 times per year for an average relationship; even more for 50% of the population. If a man was afraid he would never match up with a woman’s ex, nor build the kind of bond she had with him, that would be a more reasonable fear. Not being able to live up to your partner’s ex is a real thing that may happen. You don’t even need a hormonal theory to explain it. This would be more consistent with the vole research I previously described as well (Williams et al., 1994), which relies on the fact of voles experiencing multiple subsequent orgasms to form pair bonds.

This is also more consistent with the mate-choice hypothesis of the female orgasm, which has some limited and recent preliminary support (Nebl & Gordon, 2022). The orgasm, but not sex, is said to promote long term pair bonding and the selection of mates for long term relationships.

In essence, the biological-hormonal paradigm for pair bonding relies on the female orgasm.

I am not saying you should be afraid of your partner’s ex. In fact it’s the opposite. A person who was able to establish a healthy, committed and monogamous relationship in the past will be more likely to establish one in the future. The kind of person who enters into this healthy relationship pattern will be more likely to find someone else similar to them who does as well — a manifestation of assortative mating, or the tendency to select partners who behave similar to us. Your partner’s past relationships will tell you what you can expect from them.

The point is that a sensible hypothetical mechanism for “pair bonding damage” from frequent casual sex is absent. A person who has sex with ten people in a month did not form a bond with each of those people. The mere fact that they had sex with so many people in a short period of time shows the opposite: they did not form a bond with any of them. It’s even possible that this person may have never formed a lasting long term relationship in their entire life. Extreme promiscuity is a symptom of the inability to bond, not a cause of it.

Revenge fantasies and sour grapes

I would also like to add some informed speculation of my own here. There is motivated reasoning behind the belief that “promiscuity damages a woman’s ability to pair bond.” It is fundamentally a mixture of sour grapes and a revenge fantasy.

This is a narrative passed around unsuccessful male dating communities where men express their frustrations over being excluded from sexual access. In its most extreme form incels label any non-virgins, not only the highly promiscuous, as unacceptable partners. As the likelihood of an adult incel having a relationship with an attractive promiscuous woman is next to nil, rationalizing away the desirability of it easies cognitive dissonance. It returns agency to the man. The man has not made a decision; he has had the decision made for him by women in general. It is the sour grapes fable; “I can’t get the grapes, but they look sour and I didn’t really want them anyways.”

The revenge fantasy is the depiction of failed pair bonding as a consequence for the woman’s promiscuity. It is not sufficient to state that promiscuity and pair bonding may be related. Instead, impaired pair bonding becomes a consequence and a punishment for the woman’s promiscuity. Most women did not desire the man, so one day soon they will also be undesired. The man was unable to form a relationship with any of these women, therefore those women too will be cursed with the inability to form relationships.

If promiscuity, infidelity and pair bonding outcomes are all heritable, or if the “consequences” of promiscuity are not actually consequences but third variables that precede promiscuity, it becomes less easy to turn into a karmic narrative. Impaired pair bonding can no longer be presented as a consequential outcome out of the woman’s immoral behavior. It was just a fact of her personality from the beginning. There is no karma or justice at play. Some people just get dealt a bad hand that predisposes them to dysfunctional or unfortunate behavior.

This is why the narrative is presented as gendered as well: promiscuity harms a woman’s ability to pair bond. It was never based on research on promiscuity, infidelity or relationship dissolution — nor on the genetic and hormonal effects on pair bonding. As we have seen up to this point, the research shows similar pair bonding outcomes for men and women. Promiscuous men suffer the same poor relationship outcomes that promiscuous women do. The men who created this meme, mostly men who failed to succeed in forming pair bonds themselves, are (mostly) not dating other men. They are mad at the women who won’t date them and the and women who are having sex with other people.

No direct support for the causal effect of promiscuity on pair bonding ability

When I did my literature search I did not find a single paper advancing the hypothesis that sex harms a woman’s ability to pair bond. I have not found a citation for any such paper in any of the forum posts I have read that spread the meme. If I have missed a paper please leave a comment with a reference and I will make an addendum. 

Pair bonding is not random; assortative selection for pair bonding behavior

Despite the folk wisdom of “opposites attract,” we consistently observe assortative mating in relationships. Assortative mating is the tendency to select partners similar to yourself. This is generally true for a wide range of traits and behaviors: physical appearance, social status, education level, and personality traits. It is no surprise then that we see assortative mating in pair bonding behavior.

Eisenberg et al. (2010) identified assortative mating for the 7R allele of the dopamine receptor D4 gene. As I covered in an earlier section, this is a gene that predicts (and is likely causal for) pair bonding behavior and outcomes in both men and women. Eisenberg’s genetic research showed that the ancestors of people with this gene selected others who shared the same genetic polymorphism — assortative mating. People with a greater genetic predisposition to pair bond selected others with that same predisposition. Good pair bonders enter relationships with other good pair bonders.

Horwitz et al. (2016) used the Sweden twin database (a national database of monozygotic and dizygotic twins often used for heritability research) to examine the phenotypic similarity of pair bonded couples. Again loosely aligning with the 50-0-50 rule, genetic heritability explained around 50% of the phenotypic variance in pair bonding behavior. Couples who were similar, not only behaviorally but genetically, shared similar pair bonding behavior.

This is the section that may have the most relevance for your own dating life. If you have consistently paired up with women (or men) who can’t form pair bonds, part of the explanation is you. Every person you have dated who has failed to bond with you is also a failed pair bonding on your part. You have consistently selected this type of person. They likely share a large degree of genetic and behavioral similarity to you. If no one will pair bond with you, you may be the common variable.


I have not found any research that supports the meme that promiscuity harms a woman’s ability to pair bond. However, promiscuity does co-vary with poor relationship outcomes. This is not specific or unique to women. Both the genetic polymorphisms and the personality traits predicting poor relationship outcomes are fairly consistent for men and women. Additionally, pair bonding outcomes are not random. People predisposed to poor pair bonding outcomes are more likely to select others with the same predispositions.

Point Summary

  1. Pair bonding is not a lifelong endeavor in humans (nor most mammals), but describes a series of serially monogamous relationships over the lifetime.
  2. Pair bonding behavior and poor relationship outcomes are strongly linked with genetic polymorphisms you are born with.
  3. Pair bonding behavior and poor relationship outcomes are strongly linked with personality traits that are largely heritable.
  4. No research has demonstrated a causal link between sexual behavior and poor pair bonding outcomes; promiscuity is most likely a symptom, not a cause, of poor outcomes.
  5. Pair bonding behavior is assortatively selected for. The pair bonding behavior and genetic dispositions of your partners will likely reflect your own dispositions.

  1. I appreciate the nuanced take on this red pill meme, but I do think a few points could have been better expressed/added:
    1. Sex and love have been shown to have strong neurological links in humans. This type of neurological link is only seen in monogamous species and not in any non-monogamous species. This is what is meant by “sex causing neurological changes”(They’re not changes per se, but the pre-existence of an interconnection between two brain systems):

    “One notable difference is the lack of OXTR in reward regions such as the ventral pallidum and nucleus accumbens in chimpanzees, whereas OXTR is found in these regions in humans.”

    “Our results suggest that in chimpanzees, like in most other anthropoid primates studied to date, OXTR has a more restricted distribution than AVPR1a, while in humans the reverse pattern has been reported.”
    The reason we pair bond is mainly due to the high distribution of OXTR receptors in the reward regions of the brain, unlike our closest relatives and 70% of primates.
    This article goes into more detail about the maps that show the interconnection between love and sex
    2. There are primates that form lifelong pair bonds. I am only aware of three: Azara’s owl monkeys, Coppery Titi monkeys and certain species of Golden Lion Tamarins, but there are more examples of primates forming lifelong pair bonds.
    The reference Lukas and Clutton-Brock study shows that the 3-5% number is outdated and the number of monogamous species in mammals is 9%.
    There is plenty of anthropological and evolutionary biology studies showing that monogamy is biologically predisposed in humans and that monogamy has originated anywhere between 2-6 million years ago, but that is a topic for another day.

    3. I think you made a mistake when you said that Harden (2014) shows all the correlations being between 30-60% because if you look at the third column properly, 4 out of 18 correlations present are <30%(16%, 0%, 21%, 6%). Not sure if this was intentional or if this was a mistake.

    4. There are studies that support the oxytocin desensitization theory that red piller spread, but the reason for the desensitization has nothing to do with the actual act of sex, but it has to do with alcohol and drug consumption that frequently occurs in casual sex encounters:

    "Thus, the generally opposite associations found in the present study, when compared to findings from studies on individuals with heavier levels of alcohol use, may represent acute effects that over more prolonged and intense durations would eventually lead to downregulation and desensitization of the OT system."

    " In fact, preclinical evidence largely indicates that chronic exposure to a variety of drugs, including alcohol, reduces OT production and signaling (Lee et al., 2016; Light et al., 2004; Peris et al., 2020). "

    The above study provides the reason why people with high n counts are more likely to have impaired bonding. Keep in mind that the vast majority of hookups/casual sex encounters involve the usage of alcohol and/or drugs in order to let go of inhibitions. As shown by this 2022 study, heavy alcohol consumption seen in hookups lead to desensitization and downregulation of OT system.

    There is plenty of evidence to show that alcohol consumption leads to increased sexual promiscuity because alcohol removes inhibitions and promotes impulsivity.

    "However, continuous exposure to high doses of oxytocin leads to desensitization and down- regulation of OTR (Plested and Bernal, 2001)."

    "Alcohol inhibits oxytocin release from hypophyseal terminals in males and females. Alcohol affects centers of oxytocin production in males and females. Alcohol's effects on the oxytocin system can change with repeated exposure. Oxytocin administration tends to decrease alcohol consumption in males and females."

    5. While going through all the research that shows a genetic predisposition towards promiscuity and/or infidelity, I couldn't help but notice that genetic promiscuity and infidelity is mainly caused by genetic defects/defective variants of normal genes rather than normal genes causing people to have this behavior, but you didn't seem to mention that all the studies you linked show genetic defects being the reason why some people are promiscuous. Was this done in fear of getting backlash from promiscuous people? Garcia 2010 and other studies have explicitly mentioned that defective variants cause promiscuity and infidelity.

    6. Pair bonding in long term relationships do not get damaged at all. If anything, the strength of the pair bond in a relationship gets stronger and more cemented compared to non-exclusive, casual relationships. As mentioned in Point 4, heavy alcohol and drug use damages a person's ability to pair-bond. Being in a long term relationship does not desensitize a person:
    "Findings for our relationship satisfaction classes are consistent with growing evidence suggesting that declining satisfaction trajectories are not normative, but tend to be pulled down by a small subset of the sample that show more dramatic declines(Galatzer‐Levy et al, 2011; Karney & Bradbury, 2020)."
    As shown in the above 5 studies, people with high levels of oxytocin remained together and those with low levels split off. The satisfaction in long term marriages remained stable over long periods of time.

    It was also shown that girls who were abused had abnormally high levels of oxytocin, which then leads them to live a promiscuous lifestyle:

    Finally, contrary to the claims of red pillers, Millennials and Gen Z'ers are having less sex compared to previous generation and this is a well documented phenomenon, which thankfully, you have mentioned. Here are more stats and research proving this:

    Some studies that I think should be added to provide the reader with more information:

    I apologize for the very long answer, but I think these points are also important to consider as well

    1. Thank you for your very good and well thought out comment Roy! For point 3, the low correlations under c2 are the shared environmental correlations. Typically shared environment accounts for very little: the 0 in the 50/0/50 rule. Very interesting information regarding the role of alcohol in impaired pair bonding and this would explain a lot.

      1. Hi Alexander,
        I have done a bit more research into the role of alcohol in impaired pair bonding and it pleases me to let you know that this hypothesis is well researched and well supported, which debunks incel claims about impaired pair bonding. I will provide the research below:

        “Alcohol consumption has been consistently linked to hooking up such that those who consume alcohol at high levels and use it more often are more likely than those who do not to engage in hookups overall, to hook up more frequently, and to report having a greater number of hookup partners (Desiderato and Crawford, 1995; Owen et al., 2010, 2011; Barriger and Vélez-Blasini, 2013; Olmstead et al., 2013a; Bernston et al., 2014; LaBrie et al., 2014; Roberson et al., 2015; Thomson et al., 2015). Although most research in this area has been conducted on college students, the general relationship between overall alcohol use and hooking up has been upheld in middle and high school students (Fortunato et al., 2010; Johnson, 2013). ”

        “Research examining hookup scripts described in young adults’ most recent hookup encounters found that 31.2% explicitly mentioned alcohol use while 16.2% implied the presence of alcohol with only 1% overtly stating that alcohol was not a factor in their most recent hook-up (Olmstead et al., 2018).”

        ” Indeed, hooking up and alcohol use do not only seem to co-occur, but in many young adults’ and adolescents’ schemas regarding hooking up, alcohol is involved (e.g., Holman and Sillars, 2012; Livingston et al., 2012)”

        “Alcohol use is a very common prelude to hookups among college students. Women consume a median of four drinks before or during a hookup (England et al.2007). ”

        “Sexting, alcohol use, and sex-related alcohol expectancies were involved in hookups.”

        “Several studies collected only subjective reports about the sexual arousal and the orgasm. Most of the studies found higher levels of oxytocin during the orgasm or ejaculation.”

        The reason sex causes emotional attachments is because oxytocin levels are the highest during orgasm, which leads to formation of a pair bond. Any other activity that releases oxytocin does not lead to pair bond formation due to insufficient quantity. This is in line with Nebl & Gordon 2022 who claimed that orgasm from sex may be responsible for pair bond formation. Pair bonding is responsible for the intrinsic links between sex and attachment, as provided in my previous comment.

        Studies have shown that alcohol delays the oxytocin receptor signaling and leads to desensitization:

        “Thus, the generally opposite associations found in the present study, when compared to findings from studies on individuals with heavier levels of alcohol use, may represent acute effects that over more prolonged and intense durations would eventually lead to downregulation and desensitization of the OT system.”

        ” In fact, preclinical evidence largely indicates that chronic exposure to a variety of drugs, including alcohol, reduces OT production and signaling (Lee et al., 2016; Light et al., 2004; Peris et al., 2020). ”

        “Alcohol inhibits oxytocin release from hypophyseal terminals in males and females. Alcohol affects centers of oxytocin production in males and females. Alcohol’s effects on the oxytocin system can change with repeated exposure. Oxytocin administration tends to decrease alcohol consumption in males and females.”

        “Numerous studies have reported altered OXT signaling in the brain following both acute and chronic exposure to alcohol and drugs. ”

        “Taken together, the majority of studies indicate that acute alcohol exposure inhibits release of OXT induced by various factors in male and female human and non-human subjects. These studies also demonstrate that OXT levels typically normalized back to baseline levels following a decrease in blood alcohol levels.”

        “There is a substantial amount of evidence that a single alcohol exposure suppresses exogenously and endogenously-evoked increases in OXT release into the blood stream.”

        Neurobiological mechanisms of social attachment and pair bonding

        “As in humans, drugs of abuse impair the ability to form social attachments in prairie voles, presumably due to plastic changes in underlying neural circuits.”

        In fact, research has shown that oxytocin can be used to treat alcohol disorders due to its ability to reduce alcohol cravings:

        “Central OXT administration has been shown to inhibit drug and alcohol induced increases in dopamine in mesolimbic regions, particularly the NAc (Kovacs et al., 1998, Peters et al., 2017).”

        There is evidence of oxytocin receptor degeneration due to desensitization and repeated exposure:

        “For both OXTR and V2, there is evidence for rapid receptor desensitization, via receptor internalization. In vitro studies suggest this desensitization effect may be present minutes to hours after exposure to the peptide, and can result in >50% internalization of receptors (Gimpl and Fahrenholz, 2001).”

        “However, continuous exposure to high doses of oxytocin leads to desensitization and down- regulation of OTR (Plested and Bernal, 2001).”

        1. Unfortunately you completely threw any semblance of credibility out of the window when you decided to label people red pillers and incels. Shows an undertone of extreme bias in your reasoning. To be a good critical thinker, you need to first tackle your predisposition and you failed miserably at first base. Do better next time.

          1. “Unfortunately you completely threw any semblance of credibility out of the window when you decided to label people red pillers and incels.”

            Credibility is determined by validity and reliability of the evidence provided, not by the terminology I use to describe a real group of mostly online men who often distort science in order to support their victim narratives.

            “Shows an undertone of extreme bias in your reasoning.”

            And yet when you read my comments, it becomes clear that my reasoning is the furthest thing from biased.

            “To be a good critical thinker, you need to first tackle your predisposition and you failed miserably at first base. Do better next time.”

            You failed even more miserably than I did by incorrectly assuming my reasoning what built on the foundation of me using the terms “red piller” and “incels”. Its almost as if you are trying to find reasons to disregard the evidence I have found, it seems. Reread my comments, try to understand the point I am making and please do better.

          2. Correction to my previous response:

            The terms “red pillers” and “incels” aren’t labels I invented out of thin air. Those terms refer to a real online movement and community of men who more often than not misrepresent science in order to support their narratives of being victims and justifying their misogyny.

            Just take a look at some of the comments posted by such people under this article.

            The main reason Alexander wrote this article is to shed light on the common misrepresentations and unwarranted assumptions made by members of those two communities.

            With this in mind, your accusation of extreme bias is very weird and unwarranted(I would suggest you drop the hyperbolic “extreme” you used. You don’t even show that I am biased, you cherry pick two words I used, ignore the rest of the comment and accuse me of bias).

            Unless you show that I am biased by showing that I have ignored evidence that undermines my reasoning, I’d say my critical thinking skills are just fine and your accusations are unwarranted.

    2. OI Roy, can you provide me studies and reasons for monogamy exist for humans. I am a evolutionary psychologist student, i know that monogamy exist for probably 4 milions of years in our species , the studies made by Helen Fischer prove that, but i need more articles about this theme. I want to made my work about this theme. So if you talk what you know and show me the articles I will apreciate. Sorry, for the bad english , i am from Portugal.

      1. Hello Diogo,
        I can very surely provide the studies that show that humans have been monogamous for millions of years. I found a very good compilation of all the studies here:

        I apologize for the usage of a Reddit link, as most people here tend to not take anything from Reddit seriously.
        The above link has around 260+ studies not only proving that monogamy is natural for humans, but it also debunks a lot of sensationalistic, pop pseudoscience.

        The claim that humans are naturally polygamous has been debunked here:

        The research supporting the claim that humans are a pair bonding species is provided here:

        I hope this helps

      2. Hi Diogo,
        I initially presented all the links, but my comment was removed for some reason. Here are all of the links presenting the evidence that monogamy existed for millions of years:

        Pair bonding, which is a synonymous term for monogamy has existed for millions of years as well:

        More evidence supporting the idea that monogamy evolved a long time ago:

        Hope this helps

          1. Well, no, cause now we have to get into the scientific flaws of carbon dating and how the mathematics of carbon dating are assumptions that evolution/old earth theory is true.

            Much like how you twisted the narrative of promiscuity hurting pair bonding despite your studies proving just that. However you heavily lean on the effects of alcohol/drugs as the excuse for pair bond damage. A bait and switch tactic.

            It’s always important to understand that science does not explain science. Humans with an emotional bias explain science.

          2. Ammonzy’s comment is a great example of how science deniers twist their enemies words in order to push a false narrative.

            Its clear to me you know nothing about paleontology since you falsely assume that carbon dating is used to measure age of fossils (Reno, Lovejoy, Plavcan and the others would laugh at your nonsensical assertation), but go on and expose yourself as a creationist fool.

            I never twisted the narrative on promiscuity damaging pair bonding and I explicitly state that a few points in the article could be better explained. Alcohol and drugs do explain quite a lot as to why pair bonding gets damaged and we have plenty of research, all of which I cited to show that the usage of alcohol/drugs is ubiquitous in casual sex scenarios, something you deny because it goes against your feelings and biases.

            The scientific method is designed in a way that it reduces/removes biases when performing research studies, which further proves that your statement “It’s always important to understand that science does not explain science. Humans with an emotional bias explain science.” is not only false, but it reeks of scientific illiteracy

  2. Most cultures have shamed promiscuity. As feminists note, they shame women more than men for promiscuity. If promiscuity does not cause problems but is a symptom of the problems it is supposed to cause, are these cultures maladaptive?

    1. True. In rural India, forget promiscuity on the woman’s part; even losing virginity before marriage can get you killed as a woman. Literally. It’s called honour killing of girls/women. The shadows hang around the urban groups too. Indian culture, when it comes to women, shifts from Hinduism/Sanatan to Abrahamic. Don’t get fooled by Goddess worship. On the other hand, men can r*pe & get away most of the time especially if they have connections. Nobody bats an eye lid at men going to s*x workers.
      There’s a common saying here that puts the double standards of the Indian society to light-
      Men with multiple partners “studs”
      Women with multiple partners “sluts”
      What a way to celebrate downgradation.

  3. First of all I really thank you for the seemingly comprehensive review on the topic.

    I do find it a bit distasteful how spend the whole article jeering at “the incels”, especially since you proved that in fact the reality is worse than what “the incels” say. It’s not that some people ruin their chances through their own behavior, but rather that some people are predisposed to having a harder time maintaining a healthy relationship.

    In end effect, the number of sexual partner is still telling so “the incels” are right, except their view is too naive. Nature is more cruel than even they imagined it could be.

    In don’t think that in such a science based blog you should waste so much time castigating people for daring to have a slightly non-PC opinion, when the opinion itself is rational. A lot about our nature as humans is not PC for the general public. That sucks but that is the way it is.

    Go tell the general public, that some of them are literally genetically flawed and will forever have broken relationships, then. Is that more PC than saying that having more sexual partners leads to an inability to pair bond?

    1. That’s a ugly truth that some of us are predisposed to having bad relationships..dosent mean we can’t change our reality …but some stuff Deff comes easier to others .

    2. Are you aware that the incels and manosphere men say that if a woman is no longer a virgin she is ruined?
      There is a huge difference between thinking that non-virgin women are ruined and thinking that some extremely promiscuous people (and we see that promiscuity is not common in humans) may have trouble bonding with others from the start.

      I don’t think this article is helpful to any man with his head washed, because they are always sliding from one position to another nonsensically. One day they tell you that non-virgin women are already ruined and that women have hundreds of partners since the age of twelve, and the next they can read an article that clarifies that promiscuity is not common in either men or women, that women have bad casual sex, and that there is no long-term relationship between promiscuity and marriage and conclude “Wow, I’m right!!!”. Women are damaged!!!!”

    3. Are you aware that the incels and manosphere men say that if a woman is no longer a virgin she is ruined? And that it doesn’t matter if incels have gf later in life, because they have “past” and they are already imprinted by Chad, that they would dating “chad leftovers” then? That women only love Chad and they only settle for men they are not attracted to because Chad no longer wants them?

      There is a huge difference between thinking that and thinking that some extremely promiscuous people (and we see that promiscuity is not common in humans) may have trouble bonding with others from the start.

      I don’t think this article is helpful to any man with his head washed, because they are always sliding from one position to another nonsensically. One day they tell you that non-virgin women are already ruined and that women have hundreds of partners since the age of twelve, and the next they can read an article that clarifies that promiscuity is not common in either men or women, that women have bad casual sex, and that there is no long-term relationship between promiscuity and marriage and conclude “Wow, I’m right!!!”. Women are damaged!!!!”

      No, incels are not right. This article dismantle the cock carousel and the imprinted alpha/Chad widow. And incels view is far from naive, they talk about women as marked cows and this article talks about women as people with different motivations and personality traits.

      You’re the one who says people are genetically flawed. Not everyone wants to get married and have a partner for life. Some enjoy being single and having sex without much strings attached.

      1. So, you love being a whore? And you want the government to support whore-ism in the name of “female sexual liberation.”

        You do have to understand that shaming the incel community is very common. The incel community, in general, wants companionship. Shaming lonely people (generally men) will only ruin society in general.

        The so-called “study” used a 0.01% exception to the rule using rodents as if implying that rodents and mammals correlate with mating neurological behavior linking to male and female brains. No woman wants to be a whore; that’s true. Because they realize it later in their epiphany phase in their 30s and above. Women are also more unhappy than ever in human history, with an increasing amount of psych meds in their vanity bags. Marriage has gone to dust, and so has women’s fertility rate. We live in a clown world where a woman can somehow become “a man” and vice versa, and other rainbow BS. People don’t even know the definition of ‘woman’ anymore.

        The premise of this article starts with the ideological presupposition that men and women are equal. And that’s where the whole article becomes useless. Here’s the thesaurus (words and emotional statements that were used in this article that went waste trying to support female promiscuity and its “farcical fallacy” to think that blaming the incel community and the men has some effect against this so-called meme:
        >prairie vole
        >limitations and generalizability
        >personality contributions and the heritability
        >mammalian exception
        >serial monogamy
        >”a problem de facto”
        >a causal relationship= Cause-and-effect
        >no research
        >own level of promiscuity
        >”pair bond impairment mechanism.”
        >”revenge fantasies and sour grapes.”
        >no direct support for the promiscuity >causal effect
        >assortative selection
        >”Both the genetic polymorphisms and the personality traits predicting poor relationship outcomes are fairly consistent for men and women.”
        >”loosely aligning with the 50-0-50 rule.”
        >”monozygotic and dizygotic twins often used for heritability research.”
        >”The men who created this meme, mostly men who failed to succeed in forming pair bonds themselves, are (mostly) not dating other men. They are mad at the women who won’t date them and those who are having sex with other people.”

        1. Who are you talking to?
          It’s always the same, incel advocates seem to be ignorant about what sexual liberation means.
          First of all, there is no “women’s sexual liberation”. There is just plain sexual liberation. Alfred Kinsey and the entire porn industry (playboy at the time) is an illustration of that. Everyone was and is free to exercise their sexuality as they please. There is no such thing as “female sexual liberation”.
          Second, such sexual liberation does not mean “being promiscuous” by default. It is being able to exercise your sexuality as you wish. I am anti-sex and sex disgusts me. In a time before sexual liberation, I would have been forced by my father to marry and forced by my husband to have sex and children, as happened to women in my family in the past. Sexual liberation is being able to choose whether or not to have sex/boyfriend/husband/husband/children.

          But obviously you are so small minded that you think it is necessary to be promiscuous to defend adult people doing what they want with their bodies and in their bedrooms. It’s ridiculous. If I defend freedom of worship am I a religious fanatic? If I defend freedom of speech then am I a great speaker? Your logic doesn’t go very far, apparently.

          Telling incels they’re not right is shaming them? Are they that fragile?
          I understand that loneliness sucks and that being a virgin as a man is stigmatized. But there is a huge gap between being a virgin who can’t manage to stop being a virgin and being a sexist man who thinks women are branded cows once they are no longer virgins and here the latter and not the former is being brought into discussion in the article.

          What you need to understand is that incels are not the only group that believes in this pair bonding theory. MGTOWs and Redpillers believe it too, so that an article discussing this idea that is linked to more groups is intrinsically linked to incels and is being discussed solely for the purpose of humiliating them makes no sense.

          All the rest of your spiel is ridiculous and all the ideas you put forth I’ve already read a hundred times.
          Antidepressants are used as a treatment for menopausal hot flashes and both married women with children and single women use antidepressants in a similar amount.
          Yes, men and women are different. Women go through menopause at age 40 and one of the treatments involves taking antidepressants, whether you have had children or not. I hope that helps.

          All the facts stated are just a crude collection of data in pursuit of supporting a conservative ideology that tries to justify by all means that the best social state is one where all women get married, give birth to babies and suck the dicks of their husbands 20 years older.

          I seriously doubt that the author of the article believes that men and women are identical, since he expounds evolutionary psychology and on twitter has made continuous threads about how men and women differ from each other in different traits and contexts. But you need to create a straw man to keep believing nonsense.

          It’s funny, but one of the most replicated differences between men and women in psychology is precisely sexual desire and promiscuity, with women being less promiscuous and having less desire than men throughout life. I fully agree with that difference, my interest in sex is nil and I continually see women talk about how they could go the rest of their lives without sex. But the joke here is that incel advocates love to believe otherwise, they love to think that women are identical to men and that they are just as or more promiscuous than men. They love to think that women are extremely crazy and interested in sex. But of course, for them the difference between men and women is not present there, it only becomes present at women’s 30s.

          I think you are the one who needs to understand that men and women are different in many ways, not the ones that accommodate the manosphere ideology or when it is convenient for your discourse.

        2. The incel community are the ones that like to shame women but people shaming them is wrong? What a hypocrite you are, this is why women run away from incels because of their double standards. We women won’t tolerate double standards anymore. You want respect then you should also give it, don’t demand what you don’t give. In the past it wasn’t popular and was badly seen to go to physiologist/psychiatrist for emotional help and women were beaten up by their husbands if they talked badly about them or could be left with nothing. So your statement of women being the unhappiest now it’s ridiculous. What you clearly don’t like is that promiscuity has the same effect on both genders and that you men don’t have more right than women to have multiple partners. If you want a woman with a low body count then you should also have a low body count. Also men and women cheating is the same. We love and enjoy sex so if you want fidelity from us you should also give it. Women in the past were ostracized and had to listen to their husband and put up with them even if they were unhappy and wanted to leave but couldn’t because they didn’t have an education or work experience. What you incels don’t like is that now you actually have to make an effort and contribute to the relationship and respect women if you want a woman. You incels want women to be unhappy and slaves. That is what bothers you that now you have to make the same effort and sacrifice as women as now a woman doesn’t have to economically depend on a man. Also we women just like men don’t like being cheated on so if you want fidelity you must give it back as it is a sacrifice from us too. Handsome young men ARE physically/sexually attractive so if you want us to be loyal you should also. Oh yeah and most girls in college cheat and none of them do it for “emotional” reasons but because the guy was “hot”. Married women that cheat don’t want a divorce either so no it isn’t emotional either ‍♀️. So those poor women of the past are the ones that could never get any help and had no choice but to be unhappy in silent. Don’t pretend that the circumstances of those women about freedom were the same as of now so comparing their so called “happiness” (according to you) is futile.

        3. No one shames incels for being incels. People shame incels for being sexist.

          “The so-called “study” used a 0.01% exception to the rule using rodents as if implying that rodents and mammals correlate with mating neurological behavior linking to male and female brains”

          What? The entire article suggest that comparing humans and animals isn’t that logical.

          “this article that went waste trying to support female promiscuity ”

          The article literally says that promiscuity has bad effect on both men and women. How is that arguing for female promiscuity ? If anything it’s arguing against both male and female promiscuity.

    4. The problem with the incels is that they only apply it to females and not males. According to them is ok for a man to have multiple partners but not for a woman. That’s the problem.

  4. We also know that microchimerism isn’t a thing because epigenetic inheritance isn’t a thing in general; the epigenome undergoes genome-wide deprogramming early in the development of primordial germ cells:
    Definitely agree on promiscuity not being causal for infidelity; both I think are caused by underlying r strategist temperament. Avoiding promiscuity is a prob good idea, as this is a way to avoid people predisposed to infidelity, but serial monogamy shouldn’t be a red flag unless they’ve had over 20 partners who all decided not to stick around for some reason.

  5. Interesting text. But I would love to see non-liberal perspective.
    I would say most guy didn’t mean what you painted about pair bonding.

  6. I was promiscuous in my early years (high school into my 20’s). Recently I met a man, fell in love with him, and married him rather quickly. I wasn’t promiscuous for love. I believed from a young age that nobody loved me (rough relationship with parents who were religious extremists). So I sold my body in various ways via sex work. The article is correct in that no pair bonds are formed in those instances when I am dating or sleeping with someone to get my bills paid. But as I got older (I am now 28) I slowed down immensely, firstly because I had a child with my on again, off again longest term relationship, and secondly because I started to desire different outcomes in treatment and goals of life accomplishments. I generally dated and slept with very wealthy men, but what was lacking was a true deep emotional connection that I so greatly desired. The problems that arise from my past promiscuity are not that I lack the ability to pair bond. It is the past treatment of men who wanted me as an object because of my looks. These things have reared their ugly heads in my current relationship. Thankfully my husband is an incredibly patient and wise man who loves me and values me despite my past. We share common goals, values and are extremely supportive of each other. I hear endless talk from both men and women on the internet about how sex workers and promiscuous women are damaged goods. While I believe it’s a great idea to speak out against promiscuity, limiting people to being “always less valuable from that point forward” is a totally flawed way of thinking. The value of humans is not determined by past sexual experiences. If you want people to rise above their circumstances and become better, more upstanding citizens of society that contribute in a meaningful way, putting them down and telling them they’re trash and will always be trash sparks no desire for change. People talking about value as if they are above those who have made some poor choices is speaking to their own ego and character. That’s why the Bible states that love is patient, kind, and forgives all things, being steadfast. People also forget, that sex work fills a void for some members of its society. The men who are able to pay get their needs met, instead of going out and taking advantage of helpless women, or killing themselves from lack of sexual needs being met. Sex work also saves a lot of womens lives, being able to quickly acquire the money to leave a terrible situation. I don’t want to sit here and say that it’s some glamorous thing to sell sex because it’s very dark, but it definitely has its place in society. And yes, the women who participate in it are still human beings who deserve love, kindness and understanding too. Outside of this, many women choose not to lead promiscuous lives, and are still demonized for having more than one partner while for men they can sleep with many people and not be looked down on. This study is dead on in the fact that promiscuity is damaging but not just to one sex. Despite all of this we are made in the image of God, creators who are able to manifest our reality. Love and peace in life can still be achieved even after having a past. I am testament to this. I am what they say is impossible. It’s all about acknowledging your mistakes and errors in thinking, and your willingness and desire to change and become a better version of yourself. I chose to rise above my circumstances. It is possible for anyone who makes the same choice. I have a very deep, strong bond with my husband despite my past. And we are accomplishing amazing things, one day at a time.

    1. After you sleep around, you become a Christian. It’s BS LIKE THIS! After enjoying the lust of the flesh, now you want God to come save you or deliver you?

    1. The fact that you resort to ad-hominem attacks without providing any evidence against all of the well designed and replicated studies presented both in the article and comments speaks more about your confirmation biases, cognitive dissonance and belief perseverance rather than the quality of studies presented here.

      1. You just said a bunch of pointless ramble. The studies presented in this very article and by Roy, another liberal, prove that promiscuity are harmful. However you can tell that they’re libs by the way they word and push a false narrative about the data.

        Science does not explain science. Humans with an emotional bias explain science.

        1. Roy’s studies do in fact show that promiscuity is harmful and its clear from his wording that he doesn’t deny this. You’re trying to justify your confirmation biases by twisting other people’s comment in order to push an agenda that has only existed in your imagination. Your accusations of “push a false narrative about the data” is clearly not supported whatsoever (Read up on what the unwarranted assumption fallacy is)

          Science explains science. The only people who deny this are humans with emotional biases such as yourself. While you’re at it, please learn what the scientific method is, as it debunks your nonsensical claim.

  7. The reason men frown upon promiscuity is because woman don’t have to do a damn thing to get sex. She can be ‘average’ at best and 9 out of 10 guys will still sleep with her. For a man to sleep with just 1 of those 10, he has to check 10 boxes on a list of a hundred. It’s when woman get into their 30’s and beyond, they now want a committed relationship. Well, what man in his right mind would want to be with, let alone kiss a mouth that’s probably had so many cocks in it? That’s disgusting and it’s why STD’s are so prevalent.
    My experience dating woman over 40, they’ll always be a man from her past she can’t detach from so any man she dated will be never be her number one choice. And no man should EVER settle for these woman. You will never have her love or loyalty the way ‘chad’ did so it’s a train wreck in the waiting. Wonder why woman instigate 70% of all divorces? It’s because they always think the grass is greener but rarely us. Just look at YouTube and TikTok videos. You woman tell us all the time how all men are evil because they’re not committing to you. No! Men are waking up and prefer casual because we didn’t set the rules, we’re just playing by your rule book. Unfortunately for you, we’re not putting the damn thing down anymore. We carry it like a bible. Cause and effect ladies.

    1. “The reason men frown upon promiscuity is because woman don’t have to do a damn thing to get sex”
      This such an utteraly false claim. Also this isn’t even the reason men frown upon promiscuity, It’s just a cultural thing.

      “She can be ‘average’ at best and 9 out of 10 guys will still sleep with her. ”
      They won’t. Even statistics shows men seeks women who are better looking than them and women are fine with men uglier than them.
      “You will never have her love or loyalty the way ‘chad’ did so it’s a train wreck in the waiting. ”
      “For a man to sleep with just 1 of those 10, he has to check 10 boxes on a list of a hundred.”
      This is also false because I know dudes with gynecomastia who sleeps around.

      ” It’s when woman get into their 30’s and beyond, they now want a committed relationship.”
      Men sleep around for longer and have more sex and want to have a commited relationship when they are in their 30s.

      “Well, what man in his right mind would want to be with, let alone kiss a mouth that’s probably had so many cocks in it? That’s disgusting and it’s why STD’s are so prevalent.”
      I mean, the same claim would be made toward men too.

      “You will never have her love or loyalty the way ‘chad’ did so it’s a train wreck in the waiting. ”
      Both men and women in general are less loyal if they were promiscuous

      “Wonder why woman instigate 70% of all divorces? ”
      1. Because men cheat more 2. Men cause domestic violence more than women

      “It’s because they always think the grass is greener but rarely us”
      You do realize that men cheat way more than women right ?
      “You woman tell us all the time how all men are evil because they’re not committing to you. ”
      This is a claim made way before sexual liberation stuff

      “Men are waking up and prefer casual because we didn’t set the rules, we’re just playing by your rule book”
      I don’t like this weird emasculation of men as if women have so much power over men. I am not saying that women didn’t affect the rules, but men certainly made the rules in pretty much every culture.

      “Cause and effect ladies.”

      So, women are sluts and men gonna be even more of sluts to counter that ?

    2. Literally most of what you said has been debunked in the post and comments. Your unawareness that women are also human beings that don’t just react to some biological impulses you made up in your head is utterly horrific.
      One thing I want to reply is this: “The reason men frown upon promiscuity is because woman don’t have to do a damn thing to get sex.” LOL. How is this a valid argument? It is easier for women to get sex, not as easy as you made it to but okay let’s give you that. So you’re saying, women shouldn’t have sex just because men are jealous it’s easier for them? So what, should men abstain from lifting heavy things because generally it’s easier for them? Should tall men abstain from basketball just because it’s easier for them, and just leave short people to play? Not only did your comment degrade men and reduce them to insecure crybabies, but it makes zero sense. Yes, most divorces are instigated by women. But, do you know who instigates divorces during hardships? Men! When a partner is ill from cancer, men divorce significantly more. Also, in relationships where women earn as much or more than the man, they still do the majority of housework and childcare. Most victims of domestic abuse are women. And then you wonder why women divorce so often. You have never bothered to think that marriages are often way worse for women. But no, the reason why women divorce is because Chad left an imprint on her! (Even tho it’s the men who bring up their past relationships more).

  8. Unfortunately your missing the whole premise of telegony and microchimerism which is the genetic material in the seminal fluid of the first mate. Safe sex counts might I add. Your immune system has to take a piece of that information as does so forever at your own demise you now have a higher risk of neuro degenerative disease but will also pass traits of that first mate unto progeny that’s not his. The higher infidelity correlation with higher divorce rates seem to be gender cheery picked by you but overall we see sharp correlation between the two and a causative agent in charge of modulating the biological future after copulation protected or not. This is where pair bond research will take off. I am sorry to see your article completely miss this tangible aspect to the equation

  9. I don’t have strong reasons to believe that the pair-bound damage hypothesis is true, but if I were to model such an effect, I would model it as a Pseudo-Abandonment –> Pair-Bond Reluctance. I would then define Psuedo-Abandoment as the cessation of male attachment between intercourse and the next menstrual cycle. I’m not suggesting this window is magic, but it’s straightforward to define, and I can give an intuitive meaning. Which goes like this: the cessation of male attachment during pregnancy is True Abandonment and it should be obvious why this is a poor outcome. Pseudo-Abandoment is abandonment during the period when pregnancy is a possibility but is not confirmed. In and of itself, Psuedo-Abandonment is not a poor outcome, but it is a poor signal.

    We can easily imagine that multiple episodes of True Abandonment would be highly traumatic.We should then expect reliable signals of True Abandonment to be slightly traumatic. Otherwise, you are leaving adaptation on the table. Anything that hurts should also kinda hurt in reliable expectation.

    The promiscuous women, almost by definition, experience many episodes of Pseudo-Abandonment. We should thus expect that she experiencing mild trauma. This is theoretically convenient because it also explains female reluctance for casual sex. Ideally, the whole system of psychological adaptations should be integrated and self-equilibrating. So, if we expect to as a side effect something we know we get, then that’s good, even if the side-effect is not the primary driver of that outcome. But I digress.

    The point is that this mild repeated trauma is causing pair-bond reluctance. Now, here comes the second part of the model, which is very important. In the wild type we should expect that this trauma “works”. That is that the Psuedo-Abandoment occurred not as a resulyof promiscuity but of a false interpretation of the male’s intentions.

    Thus pair-bond reluctance is adaptative. It helps to fine-tune the expectations of men. If we think that promiscuity is a disfunction — lets just attribute it to low impulse control for simplicity — then the trauma becomes pathological. It does not serve to stop the activity that’s causing it. The female’s expectations are over-tuned. She holds back compulsively. This is how permanent damage sets in.

    Our current society might exacerbate this, in fact, because it presents causal sex as an alternative to pair bonding. Thus, a woman who is traumatized by pair bonding as a result of promiscuity will be socially encouraged to engage in more promiscuity. Promiscuity functions like a narcotic, encouraging greater and greater dependence on the very so of the increased tolerance. We’d expect then that at some point, the woman may be driven to promiscuity, not even as an alternative to pair bonding but as a necessity for emotional well-being. This is attractive because it mimics reports that “I needed sex to feel good about myself” that is stereotypically reported.

    So this is the type model I would be thinking in terms. Again, I have no particular reason to think the phenomenon is real, but I am a theorist by training, so

  10. Whores are disgusting, and there is no research that is going to change that. “Serial monogamy” is disgusting, hypocritical, and should be eradicated from society. You should either keep your vows for life or put a red light in your window–no exceptions. I can’t stand modernism nor postmodernism, and I will have nothing to do with any of this nonsense. Those who lack discipline and honor are literally beasts and do not deserve any sort of rights. I did not conduct my life strictly and with honor to accept disgusting behavior from females. I never accepted it from myself, and I will never accept it from any of you.

    P.S. pair bonding is irrelevant when so many women will cheat and/or divorce without a second thought, including damaging children in the whole deal.

  11. The military has done studies on women, cheating, divorce and IQ. You won’t be able to access private research on these topics even if you claim to be the most sublime scientist. History has proven out the meme without the assistance of science. The data is there but you are lacking the ability to identify it in the one single place you can find millions of accounts, the American court system. Scientists that aren’t willing to sit through a few years of family court along with engaging the records of lawyers that have practice their entire lives are never going find reliable answers asking women. They are never going to look at the private emails, phone recordings, and text messages left by millions of women that have intentionally sabotage the lives of their family’s out of spite. How many of their children’s lives have been lost due to impulsive familial sabotage. How many police records of women that have committed crimes against their own children trying to get back at their exes have you documented or reviewed. The answer is none. Pathological altruists exist in academia at all levels.

    They will lie and slight anyone who would attempt to shed light on the inconsistent actions of females that cause emotional or physical distress to their families across time.

    So no one should believe you have any credibility provided to you by academics practicing and endorsing cognitive dissonance as science.
