Yes I've heard lots of weak people discussing a fear of competing in a wider talent pool and then crying about "bias" as an excuse rather than taking responsibility for their own results.

We hear often about isms of all sorts, but as soon as someone mentions an unsympathetic group, all of a sudden isms magically disappear. Further, even bringing up the idea is aggressively chastised.

Do I have any more information on the subject than anyone else? No.
