The main purpose of Wiki4Men is to provide a repository for information, studies, and research on men and boys and the broad range of issues affecting them, without feminist, misandric, gynocentric or woke bias. Wiki4Men also discusses issues of interest to MRAs, documents the evolution of the men's rights movement itself & misandry for posterity, and discusses issues of identity politics beyond the sphere of gender. The primary audience for Wiki4Men is MRAs, supporters of men's rights and the genuinely curious.

Starting in November 2023 topics that are more likely to be of interest to men are being added to the wiki.

Often claimed to have been discredited.

Absolutely proven in certain areas: height weight, hand size.

Compelling evidence for personality.

Very strong evidence for IQ, and this is true regardless of what IQ means.

Opponents are free claim it isn't true in a particular area, and in some cases this is likely true. Robert Brockway mentioned the possibility of counter-examples in this original article.

Male variability doesn't claim to be universally true just generally true.

Robert Brockway postulates that counter-examples exist and that, in particular, female sexual response is a counter-example. Women, on average, take longer to achieve orgasm than men, but more importantly there facility to orgasm varies significantly more. A man with a widely variant sexual response may ejaculate less frequently. This would be a negative selective pressure which would favour men with a more conventional sexual response. Thus natural selection keeps the male sexual response within narrow bounds, overcoming male variability. In contrast female sexual response is able to vary widely.

This study claims that male reaction time is less variable - a possible counter example.
