Study finds around half of hetero men surveyed prefer partner who is sometimes attracted to women, but around 10% hetero women say same

Hetero men in short-term relationships are more likely to want their partner to sometimes have sex with women than those in long-term r/s

In order to make the case for evolutionary drive, they would need longitudinal data over generations. Instead, they have 590 psych students

Also, that women reported being less interested in seeing their imaginary partners with other imaginary men is seen as evidence of evolution

It isn't; Western popular cuture (romance, erotica, pornography) produces less materials appropriating gay men's sex for hetero women.

So there you have it: poorly designed study, with self-referential hypothesis, skewed data, & conclusions steeped in scientific heterosexism

Bad science is dangerous. It promotes acceptance of stereotypes that protects status quo. In this case, lesbians are for male consumption
