Get 'em started young.

Science, a publication of American Association for the Advancement of Science, released a peer-reviewed, data-heavy article on January 27 that, as young as the age of 6, girls as associate higher intellectual capability with boys.
"...girls were prepared to lump more boys into the 'really, really smart' category and to steer themselves away from games intended for the 'really, really smart.'"
The article suggests this may have long-term effects on what types of career choices and hobbies women pursue as they age. Hence, why there is often an imbalance of women and men in "fields whose members cherish brilliance (such as physics and philosophy)."
The authors concede that "little is known about the acquisition of this stereotype." But that, "The earlier children acquire the notion that brilliance is a male quality, the stronger its influence may be on their aspirations." Meaning, the sooner it's learned, the deeper it seeds itself in behavior.
Obviously, adult women overcome all kinds of subconscious childhood assumptions to work and live how they prefer. But these findings do serve to highlight the reality that a correlation between which sex is more intelligent starts extremely early, despite all of us being born with a brain and the ability to use it in equally as curious and competitive ways.
