filtering out manic optimists during hiring

Commenting on hiring people who challenge you, versus yes-people.

I find the hardest part is hiring 10 people you know who will be culled down to 2 or even 0 eventually, with the best of intentions. Especially when the hired are more optimistic than the hirer, and when the hirer is expressly warning the hired that the bar is high.

Then, watching the hired gradually face depression and dismay in their disregulated bipolarity by having their pathological optimism ground up in the face of reality.

I think we can all be more careful with each other.
