Mostly Cajun has put up a great post about diversity (or lack thereof) in the sciences, and how it has nothing to do with racism and everything to do with education. Those who report the statistics try to make it sound like whites are deliberately and purposefully keeping minorities out of the sciences, when such is not the case.
Minority culture, the idea that behaving in school, being respectful to your teachers, and actually learning something equates to “acting white” is what’s keeping the minorities out of the sciences.
It’s interesting to note that the statisticians reported on three groups – white, black and hispanic. No mention of Asians, a stat which I’m sure would skew the data in such a way as to not make it look so lopsided.
