likeable leaders

The thesis of this book is that leaders are often chosen more for their charisma, not their character, competence, or even true leadership ability. 

Outside of that, the point I believe my professor was making when discussing this book is that people often attribute causality for events when there is no logical connection.

Back to the book.  I haven't read it yet, but I will.  Probably won't have time until after I graduate.  The main fact is, however, people want to work with likeable people.   That isn't going to change.
