It’s okay to say “I Don’t Know”

It is also about trust. When there is trust between the employees, one is not afraid of being honest and saying "I don't know" followed by "but I will find out" or "ask Jack, he knows more about this".
If there is a feeling that punishment or implied accusations of incompetence or experience will be made, they will start making shit up on the spot.
I see this everyday. It is really sad, hours of productivity is lost because people can't be honest. Usually it goes like this. A new employee, call him N, doesn't know how something works. They don't even know who is responsible for that product area. They go to a random employee X to ask for help, so they ask "how does this work?". Employee X knows they themselves don't know, but they won't admit it and won't send employee N to the employee Y, who really knows about the stuff.
Instead employee X starts to make stuff up on the spot, or which is slightly better, they both spend hours learning about the answer by reading code (not too bad again), but all they could have done is asked employee Y about it and they would have gotten an answer in under a minute.
I often feel like a broken record when my boss comes to me and I have to answer that way. He doesn't seem to mind, but it eats away at my very soul... not to be overly dramatic, but it does cause more stress than it should.
You should never feel a question is stupid, or feel stupid for asking one. If someone makes you feel that way, and you can, find a new situation!
Did not get the job. Even made a thread about it in Ask::HN.
But not knowing something is a great motivator for me. Something that I think employers should value.
The grace/confidence in admitting they don't know, the willingness to guess and explain how they came up to it (and continuing/iterating as I give more information), and how well someone integrates something new (ie, something I have just told them) later in the interview are all major considerations in my interview feedback and hire/no-hire decision.
It's a great way to separate people who'll make up something vs people who are good at admitting what they don't know and are willing to look for the answer.
