A good leader is always looking for people smarter and more experienced than they are. If you are the smartest one in the room, then you are stupid.
In France, for example, it is not unusual for a husband to have a wife and a mistress. However, if in addition to these two he's also having a fling with a fringe tootsie, both the wife and the mistress are outraged and the combination lover, husband, and cheat may well wind up with a large French bread knife between his ribs.
