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.

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.
