It'd be an irony if part of the reason students at HBCUs don't "mesh" with Silicon Valley is that they're not comfortable with diverse environments. Looking at a list of the "whitest" universities, their graduates seem similarly unrepresented in the places I've worked.
A flawed but interesting test: do black CS graduates from Stanford and MIT fit better into SV than black CS graduates from Howard?
As a black alum from MIT and feel I can speak to this anecdotally. Here are some distinction to keep in mind.
1) From the moment I stepped onto MIT's campus I was actively recruited by Silicon Valley companies. My freshman year was tough getting much attention, but recruiters would talk to me and generally gave off the vibe that I was wanted. Contrast this with going to a HBCU where these companies are not present on campus, or if they do show up its only for a day or two for a career fair. You wouldn't feel as welcome coming there.
2) I had black friends who were upperclassman who had "made it" in SV. They could offer advice and guidance. When I moved out to SV I also had them as part of social circle so I had social ties outside of work. Coming from a HBCU its likely you do not know anyone who works at these companies. You also do not know anyone who lives in the area to socialize this. If you do not relate to the people from work then you have trouble making friends.
I don't know how you'd measure fit (tenure at first job? % that change jobs to another SV company?), but it should be pretty easy to get hiring numbers. Stanford might not be a good test simply because of proximity, but MIT certainly would be a contender.

This wouldn't surprise me. I graduated college 18 years ago, and even back then there was a huge amount of diversity in my graduating class. I had friends from India, Taiwan, Indonesia, Turkey, Ghana, etc. However, there were very, very few African-Americans (the guy from Ghana doesn't count). Nor were there any Hispanics that I recall. So someone from my university would have fit in pretty well in SV in a diverse work team (and they did, lots of my classmates went there).
So I think your test isn't flawed at all, but a very worthwhile question.
