I mean more than average. Your anecdotal experience is higher than the number in the study, so the most likely explanation is that you've worked in companies that have a higher incidence than the average company. The study could also be of companies with less sexist behavior than average, but their sample size is almost certainly larger, so that's less likely. Or maybe their methodology is bad, or maybe you misinterpreted the behavior, or maybe the whole thing is an LLM hallucination and I'm screaming into the void, but the first explanation is the most likely.
