Non-Binary and Rare Orientations Show Higher IQ, Claims New Study

A recent study conducted by researchers Edward Dutton and Emil Kirkegaard has found significant links between intelligence and both non-binary gender identities and rare sexual orientations. Using a large dataset from the dating site OKCupid, the researchers explored the relationships between sexual orientation, gender identity, and intelligence. The findings, published in Psychreg Journal of Psychology, indicate that individuals with non-binary gender identities and rare sexual orientations tend to have higher intelligence scores compared to their heterosexual and binary gender counterparts.

Previous research has suggested that there might be intelligence differences among various sexual orientations and gender identities. This study aimed to investigate these differences using a robust dataset from OKCupid, comprising approximately 36,866 users. The dataset predominantly included users from Western, English-speaking countries, with a mean age of 31.7 years.

The study examined intelligence scores in relation to sexual orientation (heterosexual, bisexual, homosexual, and other rare orientations) and gender identity (man, woman, non-binary). Intelligence was assessed using a collection of 14 multiple-choice questions. Although the measure had a reliability score of only 0.62, it has been validated in previous studies as an effective intelligence test.

The study found that non-binary individuals, when considered alone, showed a substantial intelligence advantage. However, when both gender identity and sexual orientation were analysed together, the intelligence difference attributed to non-binary identity was mediated by the strong association with rare sexual orientations. This indicates that the elevated intelligence scores observed in non-binary individuals could be largely due to their association with rare sexual orientations.

In terms of sexual orientation, bisexual individuals scored slightly higher on intelligence tests than heterosexuals, while those with rare sexual orientations scored significantly higher. Homosexual individuals scored slightly lower than heterosexuals. Specifically, the intelligence scores were as follows:

  • Heterosexuals served as the reference group.
  • Bisexuals had a coefficient (β) of 0.17, corrected to 0.22.
  • Homosexuals had a coefficient (β) of -0.07, corrected to -0.09.
  • Individuals with rare sexual orientations had a coefficient (β) of 0.73, corrected to 0.93.

Regarding gender identity, men scored higher than women, with a corrected coefficient (β) of 0.14, equating to about 2.1 IQ points. Non-binary individuals showed no significant difference from men in the combined analysis, but they exhibited elevated intelligence when analysed separately.

The researchers discussed several potential explanations for these findings. One hypothesis is the Savanna-IQ Interaction Hypothesis, proposed by Kanazawa, which suggests that higher intelligence is associated with preferences that are evolutionarily novel, such as non-binary gender identities and rare sexual orientations. This is because high intelligence may enable individuals to rise above cognitive biases and explore non-instinctive possibilities.

Another explanation is the Cultural Mediation Hypothesis, which posits that intelligent individuals are more adept at understanding and conforming to dominant cultural norms. In recent years, there has been a cultural shift towards recognising and valorising marginalised groups, such as those with non-binary gender identities and rare sexual orientations. This could incentivise intelligent individuals to identify with these groups.

The researchers noted that intelligence is associated with environmental sensitivity and plasticity. This means that intelligent individuals may require specific environmental conditions to develop their sexuality and gender identity adaptively. The decline of traditional methods of raising children, such as fixed gender roles and corporal punishment, might influence these associations.
