You’re right, so I just changed it. I got lazy when posting it and just used the suggested title as provided.

This article is not really about mathematical talent. It mentions that stereotypes might be reproduced by attributing success in girls to diligence and in boys to talent, but it’s about mathematical ability.

At the start of the first school year (when children are five or six years old), there are no differences, on average, between boys and girls in mathematical ability. But after just four months, boys have pulled ahead. The gap widens throughout the year.
