===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">On average, women are attracted to the Dark Triad—narcissism, manipulativeness, & psychopathy</span>===

----

The [[dark triad]] is defined as: '''Narcissism''', '''Manipulativeness''', & '''[[asshole|Psychopathy]]'''. The "Dirty Dozen" is a scoring tool for quickly quantifying the Dark Triad:

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">On PornHub, women consume most of the porn where women are violently raped and abused</span>===

----

Dr. Seth Stephens-Davidowitz, a former Google data scientist, was given complete access to PornHub's search and views data. He found that women were more than twice as likely as men to search for videos where women are abused or forced to participate in nonconsensual sex. Women preferred videos with tags like "painful anal crying", "public disgrace", "extreme brutal gangbang", "forced", or "[[rape]]".

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">62% of women have fantasies about rape and other forced sex acts</span>===

----

A team of researchers from the University of North Texas and University of Notre Dame played 355 young women a rape fantasy over headphones to investigate how aroused they became:

----

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Criminal and anti-social men have more sexual partners and have sex earlier</span>===

----

A meta-analysis of the correlates of criminal behavior by Ellis & Walsh (2000) found a strong association between criminal behavior and a greater number of reported sexual partners in men. 23 studies demonstrated a link between various forms of anti-social and criminal behavior  and greater sex partner count, including: delinquency, violent offenses, various offences, recidivism, "victimful offending", antisocial personality and conduct disorders. 20 studies found a link between illicit drug use and a greater number of sexual partners. Only one study examined failed to find a significant link between anti-social behavior and a greater sexual partner count.

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Men who exhibit antisocial  and criminal behaviors reproduce more successfully </span>===

----

Research has shown that men with antisocial and criminal tendencies have considerably higher reproductive and sexual success than men who lack this predisposition. In one study, antisocial men only represented 10% of the male cohort, but yet fathered 27% of the babies in that group. (Jaffee et al. 2003)

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Male serial killers, terrorists, and rapists receive thousands of love letters from women in prison</span>===

----

[[Hybristophilia]] is a sexual phenomenon that is defined as 'the erotic obsession with or exclusive sexual attraction with an individual who commits extremely heinous or violent crimes such as rape, murder, serial killings etc.'  

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Male gang members have dramatically more female sexual partners</span>===

----

A study by Palmer and Tilley (1995) for The Journal of Sex Research examined the possible evolutionary motives (i.e access to willing females sexual partners) that prompt young men to join street gangs. They revealed that gang members had significantly more consensual sexual partners then a comparable group of non-gang members. It was found that the leaders of these gangs by far had the highest number of sexual partners, with no male non-gang member from the sample coming even close to their high sexual partner count.  

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Childhood bullies experience greater sexual success than non-bullies</span>===

----

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">More than half of prison staff sexual misconduct involves female guards/staff</span>===

----

According to US prison guidelines, "staff sexual misconduct" includes any seemingly consensual act or behavior of a sexual nature directed toward an inmate by staff, including romantic relationships. Such acts include intentional touching of the genitalia, anus, groin, breast, inner thigh, or buttocks with the intent to abuse, arouse, or gratify sexual desire; completed, attempted, threatened, or requested sexual acts; and occurrences of indecent exposure, invasion of privacy, or staff voyeurism for sexual gratification.

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">39% of hospitalized male psychopaths had consensual sex with female mental health staff</span>===

----

Carl B. Gacono, PhD ''et al''. (1995) published a small study for the The Bulletin of the American Academy of Psychiatry and the Law comparing "select behavior indices between [[psychiatry|hospitalized insanity]] acquittees (N = 18) and hospitalized insanity acquittees who successfully malingered (N =18)". The study authors called the malingerers 'severe psychopaths', which was also evidenced by the fact that all of these malingerers engaged in physical or verbal violence against the staff of the facility, and that many of them were convicted rapists, murderers etc.

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Women desiring marriage and commitment are more attracted to narcissistic men</span>===

----   

Haslam and Montrose (2015) conducted a survey of 146 British females asking them to rate their agreement with a series of statements intended to measure their attraction to narcissism in a potential male partner. The statements were based on the Narcissistic Personality Inventory (NPI) a psychological test designed to measure the level of "sub-clinical narcissism" in an individual.

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Female narcissism reduces marital quality for men, but male narcissism does not for women</span>===

----

Lavner et al (2016) gathered longitudinal data from a community sample of 146 newlywed couples assessed 6 times over the first 4 years of marriage to assess how narcissism in men and women differentially affected marriage quality and outcomes.

----

The parents of 190 adolescents with high and low functioning [[Asperger's Syndrome|autism]] were surveyed to evaluate the adolescents' perspectives around sexuality.  

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">44.6% of high functioning adult autistic men remain virgins, despite high sex/relationship drive</span>===

----  

A group of high functioning [[Asperger's Syndrome|autistic]] men and women were evaluated and compared with healthy controls to assess their sexual and relationship desires and success/failure to achieve those desires.  

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Autists are judged as awkward, less physically attractive and less approachable within seconds</span>===

----  

Sasson et al. (2017) conducted a series of studies with a similar methodology consisting of groups of ASD (Autism Spectrum Disorder) and NT (Neurotypical) peers in various modes of social interaction consisting of 'thin slices'. The study discussed here consisted of forty adult (20 ASD; 20 NT;17 males each group) participants.  

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Autistic men have 10 times as many suicidal thoughts as normal men</span>===

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">High IQ men are more likely to remain virgins longer</span>===

----

Studies assessing the relation of IQ to sexual success in America have found that both adolescent men and women have higher rates of [[virgin|virginity]] when they have high IQ.  

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Teenage boys with ADHD have double the amount of sexual partners vs. 'normal' teens</span>===

----

Østergaard et al. (2017) conducted a nationwide cohort study using data from Danish government registers. Examining individuals (N = 2,698,052) born in Denmark between 1960-2001, it was found that individuals with ADHD were significantly (2.3 for males and 3.62 for females at the ages of 12-16) more likely to become parents in their teens. These numbers were also similar for older teenagers aged 17-19.  

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Cluster-B personality disorders lead to 3.5x as many sexual partners and more offspring</span>===

----

Guitiérrez et al. (2013) conducted a study in order to determine if the various personality disorder clusters - Type A (Schizoid, Odd), Type B (Narcissistic, Anti-social) and Type C (Avoidant, OCD) - were solely detrimental in terms of life outcomes for the individuals with these personality disorders (PDs), or if they instead presented their sufferers with various potentially adaptive benefits, such as greater sexual and social opportunities.

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Mental disorders significantly reduce male fertility, substantially more than they do for women</span>===

----

A study in 2013 examining a total of 2.3 million individuals born in Sweden in 1950-1970, using government health care records, found evidence for substantially lower fertility among sufferers of various mental illnesses. The fertility of the mentally ill was computed by measuring the fertility ratio (e.g. a FR of 0.5 would mean that the diseased group had on average half of the children of the general non-affected population, a FR of 2 would mean double the offspring on average) which reflected the mean number of children that individuals with various mental disorders had, as compared to control individuals of the same age and sex, also accounting for variables such as family size, affected status and parental status.  The youngest individuals involved, at the time their data was recorded, were 40 years old, and had thus likely largely completed their reproductive careers.   

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Women are more racist in online dating, and 92-95% with a "preference" exclude any ethnic men</span>===

----

Yahoo Personals Dating Preferences Study sought to examine the dating preferences of online daters in four major metropolitan areas: New York, Los Angeles, Chicago, and Atlanta. Internet daters' profiles of self-identified Asian, Black, Latino, and White men and women seeking opposite-sex dates were collected and coded from Yahoo Personals, which was the most popular national online dating web site in 2004 and 2005.

----

A study by Lefkowitz, Weschechelom and Leavitt (2018) consisting of a self report survey of sexual behaviour among 'first year university students' found that '''compared to their peers who had kissed partners, young adults who had never kissed were more likely to be Asian-American''', less likely to be in a romantic relationship, were less extraverted, were more likely to be in the Honors College, and drank alcohol less frequently.

The 2010 Pew Research Center Report (U.S. Census Bureau’s 2010 American Community Survey) investigated trends that year in interracial marriage. Their primary findings confirmed trends seen in other research which indicate Asian men are the least desirable to women, and black women are the least desirable to men. Overall, whites were also shown to be the least likely to interracially marry of any race. There were no gender differences in white/Hispanic interracial marriage rates overall.

Burke et al. conducted a study to examine racial homophily in preferences for opposite sex faces. 120 university students took part in the study (n=58 males, n=62 females). Participants were further comprised of three different ethnic-cultural groups: Australian-Europeans, Australian East-Asians or Hong-Kong East-Asian. Participants rated 144 colorized photographs of subjects from three racial/ethnic groups: White South Africans, Black South Africans and 'primarily Korean Asian faces'.

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Women reply most online to white men and least to Indian men</span>===

----

Data published by OkCupid shows women overall have the highest probability of replying to white men and the lowest probability of replying to Indian men. Similarly to the plight of Southeast Asian men, Indian women were actually least likely to reply to an Indian men of any race of women, showing all races of women are eager to discriminate against Indian men in dating, including especially women of the same race.

----

Bruch & Newman (2018) analyzed data from a free popular online dating site in four large American cities (New York, Boston, Chicago, and Seattle) to assess which factors people base their decisions on in online dating. They found women ranked men in a racial hierarchy of desirability as follows:

===<span style="font-family:'Linux Libertine, Georgia, Times, serif'; font-size:24px; font-weight: normal;">Women enforce stricter racial requirements than men, advantaging primarily white men</span>===

----

Lin and Lundquist (2013) found evidence of a strong racial hierarchy in women's dating preferences, and evidence for stronger racial homophily (preferring the same race as themselves) in dating, among women. The study utilized data from American dating and social networking websites, with a large final sample of n=528,000 men and n=405,021 women who resided in the 20 largest metropolitan areas in the United States. This sample was also more racially diverse than many of the samples found in other online dating studies, with 53.07% of the women sampled being white and 52.05% of the men sampled being white.

----

There exists a long-lasting [https://en.wikipedia.org/wiki/Stereotypes_of_African_Americans#Mandingo stereotype] that Black males are more sexually desired and potent then men of other races - often due to an implied view of them as being inherently more bestial in nature- particularly Whites, which is an apparent dynamic frequently exploited by those with cuckold fetish.

It has long been debated whether there is there an objective, biological basis for the experience of [[beauty]] or if it is subjective and individually or culturally driven. To determine this, researchers showed average people images of masterpieces of Classical and Renaissance sculpture, and modified versions of these arts with less mathematically ideal proportions.

Online dating app Hinge works similarly to Tinder, but was designed with the intent of creating a more equitable and better functioning dating market.

They found that young women have a far more draconian perspective on what constitutes sexual harassment compared to the previous generations of women. Young women were far more likely to view behavior that was only considered flirtatious in prior generations as now clearly sexual harassment.

An upcoming study, previewed in the Harvard Business Review surveyed individuals of both sexes regarding their perceptions of workplace sexual harassment. The researchers found that the attitudes of the men surveyed had become more exclusionary regarding their level of engagement with female colleagues at the workplace, as compared to the previous time the researchers had conducted a similar survey (2018).

A study by Grimma et al. (2015) was conducted to investigate and further elucidate on the concept of happiness and investigate what activities provide meaning and pleasure to people's lives depending on the individuals orientation to happiness (OTH). The concept of happiness was divided by the authors into the two theories of happiness held by the Ancient Greeks - hedonic happiness (minimizing pain and maximizing pleasure) and/or eudaimonia (a sense of 'meaning' and fulfillment.)

An observational study conducted by Meyers et al. (2002) of clinically depressed patients (n=165) found that being currently married was a significant protective factor against depression. Specifically, they found that being married was significantly and independently associated with a 2.4 times greater chance of achieving early remission from depression (Odds-Ratio=2.4). Being married was the only significant variable associated with an early recovery, apart from effective clinical treatment.

In this study, Grewen and collegues (2003) tested whether brief warm physical contact among cohabitating couples would reduce anxiety levels in a sample of healthy adults (66 African American, 117 Caucasian; 74 women, 109 men). The warm contact group held hands for 10 minutes while viewing a romantic video, followed by a 20-second hug with their partner. The no contact group sat quietly for 10 minutes and 20 seconds.

----

According to data from the How Couples Meet and Stay Together survey (2017), a comprehensive national survey on romantic [[Relationship|relationships]] in the US, 39% of couples met and started relationships online in 2017. The category "met online" includes online dating, but also social media and online games. At the same time, the categories "meeting through friends" or "at school" have declined, thus, meeting online has now become the leading way relationship to form. Online dating in particular is probably on a par with "Bars & Restaurants". The share of couples meeting online has almost doubled since 2009, and is currently exponentially increasing. Between 1995 to 2017, meeting through friends saw the largest decline, with 40% fewer people meeting this way. 23% of all couples met on online dating services, but the category is experiencing an exponential (logistical) increase.
