This is not surprising to me. For all I've seen "non-white non-male" is generally given priority in all kinds of areas, certainly in start-up interest. It's considered "hip" to associate with these "non-white non-male" groups, irregardless of their actual performance in whatever area they were prioritized. (To a certain extent at least, they can't be completely nonperforming) Being able to show that you have included these groups in whatever way your organization works, gives you advantages in press situations foremost, but also in other ways such as meeting arbitrary quotas set by higher-ups and HR dept.s in your organization.

This is however, given two equal applications. Such as this study shows. I would be knocking down open doors to state that white men are over represented in the "STEM/Entrepreneurship" areas. What needs to be addressed is what the underlying cause is to this over representation. For all I see there are two potential causes:

1) Non-white non-males are given less ability to grow in the "STEM/Entrepreneurship" fields as students and/or children by society. 2) White men are able to outperform those other groups by some inherent quality.

Worth noting is also that simply stating 2) as a potential cause of this difference is more or less a hatecrime in most settings, and academia would do well not to touch in attempting to work with that hypothesis if they wish to keep tenure and funding. Nevertheless, 1) seems to be partially disproved by studies just like the one above, showing that white men are in fact given less ability to grow in "STEM/Entrepreneurship" areas, as by the bias shown towards the Asian and Female applications.
