Yes, the psychology of managing is a complex topic. In the end, I think a huge problem is the simple lack of training and coaching received by new "bosses". It is often assumed that star performers will go on to be managers. The hope being that they will impart their wisdom on others. Okay...but how are they supposed to do that? What training have they had in the art of teaching and mentoring?

Being able to do something well does not imply being able to train someone else to do it. Very different skills are involved. Changing the psychology will help though new bosses will still need a lot of help.
