How many incredibly smart people are pushed out of the industry by awful people? By letting jerks run the show, you don't get a chance to see the intelligence of people who these folks suppress.
All this leads to a (despicable to me) culture of always-smiling emotional liars. If something I did is shit, say "it is shit". Make an unhappy face. Don't smile, praise my performance when cooking coffee and on the side mention that my last project "made some people somewhat happy".
But I'm not sure if that answered your question, I didn't fully understand it.
