To even suggest there are sex differences in cognitive abilities is anathema to many. Academics have been sacked for suggesting that there may be group differences in general or specific intelligence. This paper examines estimated intelligence showing evidence from 25 studies in as many countries, that females tend to give significantly lower estimates than males, around five IQ points. This coincides with current estimates of the actual difference in IQ scores. The many implications of this research area will be explained.
