But how will you know when educational opportunities are equal? If you subscribe to the idea that male IQ scores are more variable, then you will expect to see males over-represented at the extremes. If you don't subscribe to that idea, then you might expect more equal numbers. If you don't even know what to expect, then you can't discern a bias.
