Quizzing and the male

Being a regular quizzer, this is one of those things that has set me thinking. Why is the activity of quizzing dominated by males? It can't be that males are better at remembering things (try getting a man to remember important dates!). In fact, women seem to be far better at remembering the smallest of details. It can't be that men read more than women or are more receptive to information as a species. Just a thought - is it to do with any other subtle way in which the male and female brains are oriented? Seems to me it is worth pursuing the thought with some neuroscience experts. Or is it that it has nothing to do with the brain, but it is an issue of social conditioning - like girls play with Barbie dolls and boys play with cars.
