How many of us are really good at hiring great people? OK, I can see many hands up in the air. Chances are that you are wrong - unless you suffer from depression. Twenty odd years back two grad students from Univ of Pennsylvania found out that depressed people are better judges of how much skill they have.

Why do you think people get hysterical during appraisal discussions unless they have allowed to wear their personal halo and wings.
