Depends what you mean. Girls have a higher average IQ than guys but guys are more evenly spread out throughout the spectrum. If we are talking about EQ Girls are generally higher always. In terms of "school smarts" guys have the edge. Overall I think they are about equal but different.

I assume you mean overall, on average. Men tend to perform better in certain cognitive tasks while women tend to perform better in certain other cognitive tasks. And there's more variety in the male population's IQs, meaning there are more men with very high IQs but also more men with very low IQs.
