Here's a graph based on users' self-reported MBTI types (users who didn't select an MBTI type were ignored). The way it works is that one of the two possible answers for each of the four dichotomies appears on the graph, along with bars showing the percentage of users in a particular category which selected that option rather than its opposite. For example: the graph shows that 60% of administrators were E (extroversion), therefore the remaning 40% were I (introversion).
* excluding
Demo.
† the top 25 non-staff posters.
Same chart, different way of looking at it:
Sample sizes: administrators, 5; cool guys, 3; global moderators, 7; moderators, 17; top 25 posters, 21; top 25 proles, 19.
Conclusion: to become moderators, the proles should think more.
