TL;DR version, James Damore works for Google, researches scientific sources for gender definitions. Compiles each definition and factor into a document that uses neutral third party citations and peer review to back up his citations.

Gets fired over SJW Politics, accusing him of making gender stereotypes by people using politics, culture, society for gender definitions, Google panics over the protesters, feminists, social justice warriors, etc upset over the document and under pressure fire James Damore.

He was not a shitty or toxic employee, he was assigned to do scientific research on genders and compile it into a document using scientific proof.

Published on Aug 9, 2017
James Demore of Google recently wrote a memo detailing his thoughts about Google's various diversity initiatives. Inside the company, and then outside, it went viral. He lost his job, in consequence: for "perpetuating gender stereotypes." The problem is that everything James claimed is solidly backed by well-developed scientific literatures. Thus, the company that is arguably in charge of more of the world's communication than any other has now fired a promising engineer for stating a series of established scientific truths.

That's worth thinking about.

In this full 50 minute interview, James and I discuss his motivations, and the consequences of his actions. We are joined (audio only) by another Google employee who wishes, for obvious reasons, to remain anonymous.

A fund-raiser for James has been established, here: https://www.wesearchr.com/bounties/ja...
Here are a series of references buttressing each and every claim James made in his memo, which has been erroneously deemed pseudo-scientific (full papers linked where possible):

Status and sex: males and females

To quote de Bruyn et al (first reference on status and sex, above): high status predicts more mating opportunities and, thus, increased reproductive success. “This is true for human adults in many cultures, both ‘modern’ as well as ‘primitive’ (Betzig, 1986). In fact, this theory seems to be confirmed for non-human primates (Cheney, 1983; Cowlishaw and Dunbar, 1991; Dewsbury, 1982; Gray, 1985; Maslow, 1936) and other animals from widely differing ecologies (Ellis, 1995) such as squirrels (Farentinos, 1972), cockerels (Kratzer and Craig, 1980), and cockroaches (Breed, Smith, and Gall, 1980).” Status also increases female reproductive success, via a different pathway: “For females, it is generally argued that dominance is not necessarily a path to more copulations, as it is for males. It appears that important benefits bestowed upon dominant women are access to resources and less harassment from rivals (Campbell, 2002). Thus, dominant females tend to have higher offspring survival rates, at least among simians (Pusey, Williams, and Goodall, 1997); thus, dominance among females also appears to be linked to reproductive success.”
