Research

Bogaert is known for studying multiple subjects related to human sexuality, including asexuality. [1] [2] He has also published studies examining the relationship between the number of brothers a man has and his sexual orientation. These studies have concluded that the more older brothers a man has, the more likely he is to be gay, and that this effect is due to prenatal factors, not environmental ones. [3] [4] [5] [6] In his early career, Bogaert worked with J. Philippe Rushton to publish a paper hypothesizing biological evidence of Race differences. [7] This paper was critiqued two years later by Michael Lynn who stated:

First, they did not explain why natural selection would have favored different reproductive strategies for different races. Second, their data on race differences are of questionable validity because their literature review was selective and their original analyses were based on self-reports. Third, they provided no evidence that these race differences had significant effects on reproduction or that sexual restraint is a K characteristic. Finally, they did not adequately rule out environmental explanations for their data. [8]

<span class="mw-page-title-main">Romantic orientation</span> Classification of a persons romantic attraction towards others

Romantic orientation, also called affectional orientation, is the classification of the sex or gender which a person experiences romantic attraction towards or is likely to have a romantic relationship with. The term is used alongside the term "sexual orientation", as well as being used alternatively to it, based upon the perspective that sexual attraction is only a single component of a larger concept.

John Philippe Rushton was a Canadian psychologist and author. He taught at the University of Western Ontario until the early 1990s, and became known to the general public during the 1980s and 1990s for research on race and intelligence, race and crime, and other purported racial correlations.

<span class="mw-page-title-main">Sexual orientation</span> Pattern of romantic or sexual attraction

Sexual orientation is an enduring personal pattern of romantic attraction or sexual attraction to persons of the opposite sex or gender, the same sex or gender, or to both sexes or more than one gender. Patterns are generally categorized under heterosexuality, homosexuality, and bisexuality, while asexuality is sometimes identified as the fourth category.

<span class="mw-page-title-main">Biology and sexual orientation</span> Field of sexual orientation research

The relationship between biology and sexual orientation is a subject of on-going research. While scientists do not know the exact cause of sexual orientation, they theorize that it is caused by a complex interplay of genetic, hormonal, and environmental influences. However, evidence is weak for hypotheses that the post-natal social environment impacts sexual orientation, especially for males.

<span class="mw-page-title-main">Asexuality</span> Lack of sexual attraction to others

Asexuality is the lack of sexual attraction to others, or low or absent interest in or desire for sexual activity. It may be considered a sexual orientation or the lack thereof. It may also be categorized more widely, to include a broad spectrum of asexual sub-identities.

<span class="mw-page-title-main">Sexual attraction</span> Attraction on the basis of sexual desire

Sexual attraction is attraction on the basis of sexual desire or the quality of arousing such interest. Sexual attractiveness or sex appeal is an individual's ability to attract other people sexually, and is a factor in sexual selection or mate choice. The attraction can be to the physical or other qualities or traits of a person, or to such qualities in the context where they appear. The attraction may be to a person's aesthetics, movements, voice, or smell, among other things. The attraction may be enhanced by a person's adornments, clothing, perfume or hair style. It can be influenced by individual genetic, psychological, or cultural factors, or to other, more amorphous qualities. Sexual attraction is also a response to another person that depends on a combination of the person possessing the traits and on the criteria of the person who is attracted.

<span class="mw-page-title-main">Sexual fantasy</span> Class of mental image or pattern of thought

A sexual fantasy or erotic fantasy is an autoerotic mental image or pattern of thought that stirs a person's sexuality and can create or enhance sexual arousal. A sexual fantasy can be created by the person's imagination or memory, and may be triggered autonomously or by external stimulation such as erotic literature or pornography, a physical object, or sexual attraction to another person. Anything that may give rise to a sexual arousal may also produce a sexual fantasy, and sexual arousal may in turn give rise to fantasies.

Sociosexuality, sometimes called sociosexual orientation, is the individual difference in the willingness to engage in sexual activity outside of a committed relationship. Individuals who are more restricted sociosexually are less willing to engage in casual sex; they prefer greater love, commitment and emotional closeness before having sex with romantic partners. Individuals who are more unrestricted sociosexually are more willing to have casual sex and are more comfortable engaging in sex without love, commitment or closeness.

<span class="mw-page-title-main">Fraternal birth order and male sexual orientation</span> Theory of sexual orientation

Fraternal birth order, also known as the older brother effect, has been correlated with male sexual orientation, with a significant volume of research finding that the more older brothers a male has from the same mother, the greater the probability he will have a homosexual orientation. Ray Blanchard and Anthony Bogaert first identified the association in the 1990s and named it the fraternal birth order effect. Scientists have attributed the effect to a prenatal biological mechanism, since the association is only present in men with older biological brothers, and not present among men with older step-brothers and adoptive brothers. The mechanism is thought to be a maternal immune response to male fetuses, whereby antibodies neutralize male Y-proteins thought to play a role in sexual differentiation during development. This would leave some regions of the brain associated with sexual orientation in the 'female typical' arrangement – or attracted to men. Biochemical evidence for this hypothesis was identified in 2017, finding mothers with a gay son, particularly those with older brothers, had heightened levels of antibodies to the NLGN4Y Y-protein than mothers with heterosexual sons.

Human male sexuality encompasses a wide variety of feelings and behaviors. Men's feelings of attraction may be caused by various physical and social traits of their potential partner. Men's sexual behavior can be affected by many factors, including evolved predispositions, individual personality, upbringing, and culture. While most men are heterosexual, there are minorities of homosexual men and varying degrees of bisexual men.

<i>Race Differences in Intelligence</i> (book) 2006 book by Richard Lynn

Race Differences in Intelligence: An Evolutionary Analysis is a 2006 book by controversial race and intelligence writer Richard Lynn. The book reviews selected literature on IQ testing and argues that genetic racial differences exist, with a discussion of the causes and consequences. Reviews of the book fault the selection of data used, the methodology, and the conclusions drawn from the data, resulting in criticism that it is "the sort of book that gives IQ testing a bad name."

<i>Race, Evolution, and Behavior</i> 1995 book by J. Philippe Rushton

Race, Evolution, and Behavior: A Life History Perspective is a book by Canadian psychologist and author J. Philippe Rushton. Rushton was a professor of psychology at the University of Western Ontario for many years, and the head of the controversial Pioneer Fund. The first unabridged edition of the book came out in 1995, and the third, latest unabridged edition came out in 2000; abridged versions were also distributed.

A relationship between handedness and sexual orientation has been suggested by a number of researchers, who report that heterosexual individuals are somewhat more likely to be right-handed than are homosexual individuals.

<i>IQ and Global Inequality</i> 2006 book by Richard Lynn and Tatu Vanhanen

Sexual orientation is an enduring pattern of romantic or sexual attraction to persons of the opposite sex or gender, the same sex or gender, or to both sexes or more than one gender, or none of the aforementioned at all. The ultimate causes and mechanisms of sexual orientation development in humans remain unclear and many theories are speculative and controversial. However, advances in neuroscience explain and illustrate characteristics linked to sexual orientation. Studies have explored structural neural-correlates, functional and/or cognitive relationships, and developmental theories relating to sexual orientation in humans.

<span class="mw-page-title-main">Prenatal hormones and sexual orientation</span> Hormonal theory of sexuality

The hormonal theory of sexuality holds that, just as exposure to certain hormones plays a role in fetal sex differentiation, such exposure also influences the sexual orientation that emerges later in the individual. Prenatal hormones may be seen as the primary determinant of adult sexual orientation, or a co-factor.

In psychology and criminology, Differential K theory is a debunked hypothesis first proposed by Canadian psychologist J. Philippe Rushton in 1985, which attempts to apply r/K selection theory to human races. According to Rushton, this theory explains race differences in fertility, IQ, criminality, and sexual anatomy and behavior. The theory also hypothesizes that a single factor, the "K factor", affects multiple population statistics Rushton referred to as "life-history traits". It has been criticized as a key example of scientific racism and devoid of empirical basis.
