Gender imbalance on it's own doesn't say everything. You should actually talk with women in STEM. Many of them shared their horrible experiences so far.

Source?

I agree we should work to reduce horrible experiences.

My point is that we shouldn't be surprised by a gender imbalance on priors. By itself, a gender imbalance only goes to show that software engineering is like a lot of other jobs.

BTW, my suspicion is that similar experiences happen in many industries, and industries vary according to (a) how horrible a given experience is said to be and (b) social norms around registering a complaint.
