As an outsider in another country, my impression seems to be that the quest for diversity seems to have turned into something of a religion in several cultures. In principle, as a solution to the problem I am principally all in favor of anonymous, faceless, no alma mater preference etc. interviews and application processes, and/or whatever other measures are suggested to remove the possibility of bias or unconscious…
The underlying assumption is that, if you average over a large enough population, there should be no underlying consistent difference between subsets selected on gender, race, or class, so a difference of outcome is presumed to be a result of difference of opportunity.
