Fluent in Misogyny
Involuntary celibates (incels) congregate in online hateful communities organized around perceived sexual and romantic exclusion. Their discourse includes a lexicon of dehumanizing terms that is not well captured by existing dictionaries. This study developed an incel-specific dehumanization dictionary using manually coded training and validation datasets, and applied it to approximately 3.1 million forum comments. The new dictionary improved det…
Profiling the Invisible
Live-streaming child sexual abuse (LSCSA) represents a rapidly evolving and concealed form of child exploitation emerging at the intersection of technology, poverty, and opportunity. This scoping review synthesizes empirical findings to characterize the actors involved and the socioeconomic conditions facilitating LSCSA. Drawing on a thematically synthesized PRISMA-ScR approach, 12 relevant articles were identified, supplemented by an expert inte…
The radicalisation loop
Online engagement with extremist communities presents significant mental health and real-world risks. This study investigated how patterns of engagement within an incel forum relate to dynamic affective and cognitive linguistic markers. Using longitudinal linear mixed models and Linguistic Inquiry and Word Count (LIWC) on a dataset of 2,009,875 comments, spanning six years, we compared users who permanently left (Desisters), those who persisted (…
Of Lolitas and Jailbaits
Involuntary celibates (incels) comprise an online subculture of men unable to form a sexual or romantic relationship with a woman for reasons they perceive to be out of their control. As a result, they tend to hold extreme views centering around misogyny and hostility toward women. A particularly alarming aspect of their online discourse is the normalization and endorsement of sex with underage girls, which may constitute sexual abuse depending o…
The Impact of Victim and Perpetrator Race on Likelihood of Bystander Advice Post-sexual Assault
Sexual assault is a highly prevalent issue, with some individuals being more vulnerable to being sexually assaulted. Namely, women are at a higher risk than men, and within women, ethnic minorities are at a particularly high risk. Both victim and perpetrator race were previously found to impact not only the victims’ reporting behaviour but also case proceedings and bystanders’ reactions, with inter-racial sexual assault being perceived as more se…
Gender Stereotypes and Perceptions of Stranger Violence
Violence is a harmful, complex and gendered act that impacts individuals and communities financially, physically, socially and psychologically. Many studies have investigated how and why gender impacts perceptions of intimate partner violence (IPV), but little research has investigated its effect on stranger violence, despite being publicly perceived as causing greater fear and harm. Th is study examines the effects of gender attitudes and stereo…
Differential Offending as Predicted by the Dark Triad
Psychopathy is a risk factor in offending. However, there are additional traits associated with interpersonal harm that are understudied in incarcerated populations. We examined associations between the Short Dark Triad (SD3; Machiavellianism, narcissism, psychopathy) and three types of past and current offenses (drug, violent, non-violent/non-drug) in an incarcerated Iranian sample of men and women. For women, the SD3 factor analytic results had…
Moderating Effects on the Link between Violent Pornography and Sexual Aggression
Sexual violence remains a widespread problem among university students, with negative consequences ranging from mental and physical health problems to academic effects and interpersonal issues. Sexual scripts form the blueprint for sexual interactions. Such scripts are influenced by personal experience, as well as exposure to external sources. One such source is violent pornography, with its effect on sexual violence perpetration established in v…
Personality Attributions in the Context of Stalking of Ex-Intimates or Others
Stalking perpetrators may suffer from maladaptive personality traits, particularly if they stalk in the context of an (ex-)intimate relationship. To date, no study has examined how different personality attributions may relate to stalker motivation, or the behaviors they engage in, and how this differs across victim-perpetrator relationships. Further, the perspective of the victim is often not taken into consideration, even though most stalking v…
When Kinks Come to Life
Paraphilia is defined as a condition in which sexual excitement relies on fantasizing about and/or participating in unusual sexual behavior. Although recent studies have assessed the concordance between paraphilic interests and paraphilic behaviors, few studies have studied which individual traits and demographics predict engaging in paraphilic behaviors, or the level of concordance between arousal and behavior. The current study replicated and e…
Negative Responses to Child Sexual Abuse
Recently, there has been an increased societal focus on the boundaries of sexual behaviours. During a time when victims and survivors of unwanted sexual experiences are encouraged to come forward, it is vital to understand what makes people respond negatively to such disclosures. This study aimed to examine how endorsement of stereotypical ideas of Child Sexual Abuse (CSA) and response to CSA disclosures are related to various forms of attitudina…
Everyday Sadism as a Predictor of Rape Myth Acceptance and Perception of Harassment
The #MeToo movement has stressed the need to understand why individuals who witness sexual violence may or may not take action. However, prevention programs usually fail to address the association between personality traits and attitudes, perception, and behavior in the context of sexual violence. To improve prevention programs’ effectiveness, it is vital to understand how personality traits might interfere with willingness to engage in bystander…
Assessing Deception Differences with Mimicry Deception Theory
Mimicry Deception Theory (MDT) argues that deception varies along a long- to short-term continuum. Long-term deception involves complex deception, community integration, slow resource extraction, and low detectability, whereas short-term deception is the opposite. To date, no self-report scale exists that assesses a dispositional orientation toward long-term deception. Across four studies, we developed and validated a Mimicry Deception Scale (MDS…
Machiavellian flexibility in negative mate retention
Among the Dark Triad traits (psychopathy, narcissism, and Machiavellianism), Machiavellianism is uniquely associated with flexibility. This flexibility should result in the use of aggressive short‐term tactics only when they do not interfere with long‐term goals. Study 1 found that individuals high in Machiavellianism differed from those high in psychopathy with respect to retrospective accounts of negative mate retention tactics. Study 2 found a…
