He starts when an incorrect assertion and builds from there. The early days of software development saw a 50:50 mix of men and women. Clearly it isn't evolutionary traits that are holding women back. If women could succeed in the days of FORTRAN and COBOL, why can't they succeed in the days of JavaScript and Go?
Have women evolved since the 60s to make them less suited to technology? Or has the industry evolved to be less friendly towards women?
Neuroticism (higher anxiety, lower stress tolerance).This may contribute to the higher levels of anxiety women report on Googlegeist and to the lower number of women in high stress jobs.
As I said, he claims that the "average" women can't handle stress as well as the "average" man. No evidence, just stated as fact. Not that Google is even trying to hire the average man or woman anyway.
again as already pointed out there are hyperlinks removed from the article so we don't know for sure which claims are supported or unsupported with evidence, regardless I posted a paper earlier in the thread supporting that claim
as for programming in the 60s - it has changed a bit over the decades since the time of punchcards, mainframes and COBOL etc.. I'm not sure that there is much evidence that google is systematically biased against women but rather that their applicant pool is likely skewed massively towards men to begin with, the lack of women in tech perhaps could do with being addressed earlier.
Though supposing there were issues with biased hiring/discrimination - surely the better approach would be to work out where those are and try to eliminate them, by going for some token/diversity hires to fudge the numbers a bit you're just treating the symptoms not the cause, in fact you're potentially letting the underlying issues remain but just concealing them.
I suspect though the biggest causal factor here is simply the make up of the applicant pool.
