Whiteman: If X [a full professor] applies for Y [administrative job] and is not the chosen candidate, it will destroy his career.
Z: Why? He is an Endowed Professor, Chair, and Director. He will not be run out of these positions. If he applies for Y and is not the chosen candidate, can he not carry on where he is?
Whiteman: Technically, yes, but practically no. It would be too embarrassing to stay on as a Rejected Candidate for Y, and to work under the Chosen Candidate.
Z: Oh.
Axé.
coldhearted scientist وداد 
Ah yes the luxury of embarrassment.
Of course.
I have figured out what it really is. The Chosen Candidate would know that X had been a contender for his job, and would feel uncomfortable … and take steps to force X out.
It’s nearly midnight on a 12 hour teaching day (don’t ask) – and YOU MADE ME LAUGH!
The next time you talk to Whiteman, smell his breath.
