I realy wish techies woudl not persist in blindly applying simplistic anologies to complex real world suituations.
for recruitment its not quite the same its a lot harder to go to oxford or cambridge than a former polly—universities also provide networks and other advatages—hence the number of ex bullingdon club members in the current UK govenment.
What your describing is the “selecting people like me” bias that occurs in recruitment—which is also eveident in Googles bias for peope like them from stamford.
Yessss—let me guess your not a specialist in HR are you? Google have a complex and reruitment and testing pocess but they have found that people that score worse are actualy better employees.
