Dark Tetrad, Cluster B, and Patriarchy: A Data‑Driven Reality Check

In this episode, Raven pauses the “everyone is a narc” trend and walks through what the research actually shows. Raven defines Cluster B disorders and the dark tetrad, looks at how common these traits are in the general population, and highlights where men and women differ in the data. Drawing on CDC reports and Intimate Partner Violence (IPV) surveys, Raven breaks down IPV rates for heterosexual, lesbian, gay, and bisexual people, and shows clearly that abuse happens in both different‑sex and same‑sex relationships. Raven then places Lundy Bancroft’s focus on men who abuse women next to current IPV and patriarchy research, which finds a consistent link between patriarchal structures and higher male‑on‑female violence, while still documenting female and queer perpetrators. The goal is simple. Less labeling, more psychological precision, grounded only in sourced data.

Welcome back to the 515 podcast. I'm Raven, and we are going to do something a little different today. Today I want to pause on the labels and lay out some basics using data, which is kind of my favorite. When people say narcissist or narc, they usually mean narcissistic traits. Clinically, narcissistic personality disorder is one of four cluster B personality disorders, along with antisocial, borderline, and histrionic. Researchers also talk about the dark tetrad. That is a cluster of four traits measured in the general population narcissism, Machiavellianism, psychopathy, and sadism. These are dimensional traits. You see low, medium, and high levels in everyday people. High levels increase risk for aggression and exploitation, but they do not automatically mean abuser or personality disorder. When I talk about abuse here, I mean patterns. It's all about the patterns in the context. I mean patterns of physical, sexual, psychological, or stalking behavior by a partner that create harm or fear, not a single argument. Big picture, personality disorders as a whole show up in roughly 9 to 10% of adults. Cluster B disorders are the smallest slice, around 1.5 to 2.8% in community samples, depending on the study in the country. So saying everyone is cluster B does not match the numbers. Clinically significant cluster B patterns are the minority, even if traits are more widespread. On gender, men are more likely than women to be diagnosed with antisocial and narcissistic personality disorders. Some cluster B diagnoses, like borderline personality disorder, lean female in clinical samples, though community data are more mixed. For dark tetrad traits, large community studies find men score higher than women on all four dark tetrad traits on average. The high dark tetrad group has more men. The low dark tetrad group has more women. Differences are especially strong for psychopathy and sadism. So you can say clearly, high dark traits are uncommon overall. More concentrated in men, but present in all genders. Now zoom out a little bit. Zoom out from traits to behavior. CDC data from the National Intimate Partner and Sexual Violence Survey show lifetime rates of rape, physical violence, or stalking by an intimate partner as 35% of heterosexual women, 43.8% of lesbian women, and 61.1% of bisexual women. For men, around 29% of heterosexual men, around 26% of gay men, around 37% of bisexual men. So IPV is not rare. It touches a large minority of people across orientations. Who is doing the harm in those numbers matters. Among women who reported IPV, intimate partner violence, by the way, if you didn't catch that. Among women who report this, it's almost all heterosexual women with IPV report male perpetrators only. About two-thirds of lesbians with IPV report only female perpetrators. That means two things at once. Men are overwhelmingly the perpetrators when women in heterosexual relationships are abused, and women are documented perpetrators in lesbian relationships. Cohabitation data tell a similar story. One national survey summarized by advocates found lifetime physical IPV in 21.5% of men with a same-sex cohabitating partner, 35.4% of women with a same-sex cohabitating partner, 7.1% of men with only opposite sex cohabitation, 20.4% of women with only opposite sex cohabitation. So same-sex same-sex couples do show IPV rates comparable to or higher than different sex couples. Abuse happens in every configuration. And this made me think, you know, like it's still true that men are the vast majority of the perpetrators, but it happens everywhere. It's comparable and it's awful. And I do want to give a shout out and a little nod to Lundy Bancroft, who does the book Why Does He Do That. That's one of my all-time favorite books because it really opened my eyes during a lot of hard abusive times. Lundy Bancroft's work focuses on men who abuse women. He is explicit about that lens. In his own writing, he still acknowledges there are many men abused by male partners and many women abused by female partners. And the percentage of abusive same-sex relationships appears similar to street relationships. At the same time, he argues that a woman abused by a man faces a different structural context because of gendered power and social backing for male entitlement. So if you want to quote his position accurately, I guess abuse exists in same-sex relationships at similar rates. But his prior primary focus and framework remain male like remains on male violence against women in a patriarchal context. And that is really what I am coming from and discovering more and more about the patriarchal conditioning of society. So now here's the big question. Is patriarchy the problem for all genders? A major legal scholar review of social science data on IPV concludes studies consistently show a relationship between patriarchal factors and intimate partner violence. When researchers compare societies with high wife abuse to societies with low wife abuse, they see patterns. Societies with more wife abuse show economic inequality that favors men, legal or social barriers to divorce for women, male dominance in family and community decision making, more acceptance of using violence to resolve conflicts. Societies with low reported wife abuse show more equal property ownership, more balanced economic roles, and fewer constraints on leaving unsafe marriages. So at the structural level, patriarchal arrangements are associated with more male on female partner violence. Zoom back to traits, work on the dark triad or tetrad. It used to be triad, but now we added another component. But on the dark traits finds that hostile sexism explains part of the gender gap in dark traits. When you account for sexist attitudes, the difference between men's and women's dark traits scores shrink. That suggestion, that well, that interaction suggests exploitative traits plus sexist beliefs sit inside a system where men have more structural power. But the same data sets and reviews also show IPV exists in same-sex relationships where both partners share the same broad gender status. Women and queer partners can be primary perpetrators, including in relationships without a male partner. So you cannot reduce every case of abuse to patriarchy alone. Patriarchy shapes risk in context, especially for male on female violence. But individual traits and relationship dynamics also matter. But I really think it's important to say that society matters, culture matters. So I just wanted to say this because I just wanted to clear it up and I wanted to be straightforward, and I love data because data don't lie. At least that's really how I like to think about it. So, you know, to summarize, okay, clinically, cluster B refers to four specific personality disorders, and they are rare around 1.5 to 3% of adults, not half the planet. High dark traits exist along a spectrum and are more common in men, but they show up in all genders. When we look at behavior instead of diagnosis, IPV hits around one-third of heterosexual women, higher for lesbian and especially bisexual women, and around one quarter to one-third of men, depending on orientation. In heterosexual IPV, women overwhelmingly report male perpetrators. In lesbian relationships, women report female perpetrators. In same-sex couples overall, violence occurs at similar or higher rates compared with different sex couples. Lundy Bancroft centers men who abuse women, but he does acknowledge that women and queer partners abuse too, and that same-sex abuse is not rare. Across societies, stronger patriarchal structures and gender inequality go with more wife abuse. At the same time, abuse also happens in relationships without a man present, which points to individual traits and relational patterns on top of the system. So when someone calls every difficult person a narcissist or a narc, you know, or a sociopath, I've been called that so many times, it's sad. That does not line up with prevalence data. It just doesn't. It doesn't. And by the way, I've been called a sociopath by the, you know, narcissistic trait heavy people. So, and I'm sure you have too, coming from a survivor. So, anyways, most people do not meet criteria criteria for cluster B. Some people and any gender do show high dark traits and abusive behavior, and patriarchy shapes who has cover and power when they do. And that's what I want to get across as the foundation of talking about abuse and personality disorders in a way where it's like, is it a personality disorder? Probably not. So it's the first time I really did that after researching a bit, but I will make another episode soon, and I really had a great time laying this all out for you. Maybe it helped, maybe it didn't. I I like to think that data helps, it solidifies things. So, all right, I'll see you on the next episode.
