> However, the survey also reveals a colossal gap between the numbers of men and women working in top IT roles. Of the senior developers who responded to the survey, only 6% were women; with IT managers the figure was 8%, and of those heading up IT only 7% were female.
These statistics are weird together. How can this be?
Speculation: There is a bias against average/underperforming women relative to men entering and staying in tech. This means that the women who do stay in are from the upper end of the distribution. It's as if you took a normal distribution (as skill often is distributed) and truncated some segment of the lower half. This would explain why there are much fewer women reaching managerial positions but why the ones that do reach it do so very quickly.
Is there any data on how qualified and performant female engineers are relative to male engineers who occupy the same position? A result that would support this hypothesis would be something like women in the same position as men in tech have beefier academic credentials or more awards.
