Kind of a related thought on the discussion about dominating meetings, but I saw a video on instagram recently about some research with children in school playgrounds that found that boys occupy 90% of the physical space.
Almost every comment, from women as well as men, was along the lines of OBVIOUSLY boys take up more space, NATURALLY they need to run around and play with balls whereas the girls want to sit quietly round the edge. Comments like "I've been a teacher for 30 years and there is just a biological difference, boys need space to move, girls prefer to chat amongst themselves". It was laughably pointless research in fact.
So many people see it as a law of nature that boys, and men, dominate - they just need to take up more space. It's not even something people think about.
