The "over half of people thing believe they're above average at..." thing is a joke that needs to backfire in the authors face. This is a classic mean/median confusion. More than half a population *can* have an above average penis size. In a population of 100 men, if 99 measure 5 inches, and 1 measures 4 inches, then the average length is 4.95 inches. So 99 are above average, and one below.

yes, that's definitely true. And there are cases with a big mean/median contrast--money being an obvious example. If Bill Gates walks into an auditorium, everyone else has below average wealth. But the above average effect works for ranges where there is a normal distribution, such as intelligence, weight, and size of body parts.

Of course, with a normal distribution the median and mean coincide.
I still feel that when people make this joke, they're laughing because they think that above average = top half of the population.
