Somewhat premature to conclude that this 900-person study is definitive.
Agreed. I wish study replication was more gloried in science. I think there are many questionable studies out there that we take as fact.
Is this field even about "science" per se? It seems more oriented towards fashioning just-so-stories that lend a scientific veneer to some piece of folk wisdom in order to generate a buzz.
My own "experimentation" suggests that the character trait that predisposes one to bandy about pop allegories such as "marshmallow test" is a portentous sign in potential managers.
But wasn't it more premature to conclude the widely-publicized 90-person study was definitive?
