And our evidence for this discrimination is, what exactly? As I pointed out in the other reply, the evidence shows that tech companies are if anything discriminating in favor of women. If we measure by job satisfaction, computer science and engineering are among the lowest disparity: https://www.economist.com/christmas-specials/2017/12/19/wome...
As I pointed out in my other reply [1], this is a poll asking women if they think they have been discriminated against - it's measuring perceptions of discrimination. It's not measuring discrimination.
If I poll orchestra members and a lot more men say the face discrimination in hiring, but when I conduct blind auditions men do even worse what does that tell me? Or tells me that their perceptions of discrimination are out of line with the reality of discrimination.
