The data from that study didn’t even compare similar fields.
It compared a Walmart worker to a doctor lol.
It was a wild study.
This. It’s a wilfully deceptive statistical misinterpretation implying that a woman working alongside a man in the same job is magically making 20-something percent less. If businesses could get away with saving 20-30% on their biggest ongoing expense (payroll) for employees in one half of the population, they would only ever hire people from that half.
When controlled for field, role, seniority, region, etc., the disparity is within a margin of error.
