You are pulling that statement from this article: http://www.sciencedirect.com/science/article/pii/S074756329600026X
But leaving out the sentence that comes right after it:
“Gender differences in beliefs about computers approached zero and did not vary by study population. Gender differences in computer-related behaviors were small and did not differ as a function of study population.”
This issue is not the finding, it is the conclusion based on the finding — that it justifies an 80:20 ration of men to women in tech, and that other similar findings justify an even more jarring ratio (92:8) when it comes to C-level/leadership roles. To use this so-called data to suggest that there is no bias and no discrimination is an abomination.
