We women in tech frequently need to re-hash this discussion. We offer personal anecdotes, and they are written off as outliers. We present diversity numbers and pay gap data, and we are told that those are due to women either choosing family life over career or that we are biologically predisposed to not being as good as men at tech. We present data and stories about rampant, institutionalized sexism at large industry leaders, and we are scolded for being "overly sensitive". Assertiveness is conflated as bitchiness. Timidness as incompetence. The advantage is apparent - the real goal of constantly asking us to prove the advantage is to create doubt and the appearance of a controversy over the data. But I see these as thinly veiled gaslighting attempts. I have worked in tech all my life, and have had many men take credit for my initiatives and ideas, talk over me constantly through most meetings, pass me up for promotions because I didn't "engage with the team" (ie. attending late night drinking sessions at strip clubs), always get second guessed - even when I am the resident SME and was hired specifically for task, etc. I have lived it. If more men would make themselves aware of the systemic sexism in the industry instead of making women repeat themselves, argue every data point, and be 3x as good as their peers to receive recognition, maybe we could stop having this discussion . . .

There are piles of data. Seriously, you are one google away from incontrovertible evidence.
