I have no idea what the reference for it is, but there was an experiment done as to the most popular people on television shows. It was done in a University Challenge style, with the comparators being
1. A team/individual (I can't remember which)who got everything right all of the time and made no mistakes,
2. A team/individual who got almost everything right, but made a couple of really silly mistakes,
3. A team/individual who were basically incompetent.

Number 2 was the most popular every time they replicated it, varying who was playing what role.

That's you, that is.
