Would it be anywhere near as contentious if folks weren't either constantly misinterpreting the scale of the original study involved or else going No True Scotsman to death on the definition? Would anyone care as much if the job interview process in our industry wasn't also infamously infuriating? Or if enough of us weren't familiar with egotistic assholes whose productivity wasn't necessarily the result of any particular innate skill? There are a lot of confounding factors for any given anecdote.

Whether there's any fundamental truth doesn't much matter, everyone wants to bend the idea to fit their own agenda.
