I had similar experiences in my first year of university (though it was Women in Science instead of Math, a slightly larger population). It was boring.
Women in Rationality screams “pointless PC navel-gazing” because of association with these experiences.
This reminds me of an article I read about taxi drivers who would go home early after making their daily quota instead of staying on the road longer when business was good. Everyone (the drivers, their company, the potential customers) would be better off if they kept working.
Similarly, when people meet their daily quota of good deeds, they stop being good, even though it would be better for everyone (the do-gooder, their society, and the people they counterfactually could have been good to) if they kept doing good.
Is there a general quota-bias at work here? Or is my pattern-finding algorithym misfiring?
