In case you are ignorant. This is about the "things vs. people" finding. You can e.g. find it linked on wikipedia in the "Sex differences in humans" article.
If it's biological or not is kind of hard to prove without unethical experiments.
I am not disputing that there exists differences in vocational choices between genders. Programming as a discipline is a textbook sociological example though: it was women's work when it was thought as "gruntwork", and then became men's work when it got prestigious enough, almost overnight (in historical scales). If ever there exists some biological predispositions towards programming, they are largely overriden by sociological factors, to the point that using biology to explain why programmers are mostly men today is truly ridiculous.
