I have been called twice and twice ended up as the foreman. The two things I learned:
(1) If I'm ever put on trial and did what I'm accused of I want a jury - I firmly believe that half of the jurors do not have a brain in their head and can be persuaded. These are the ones who serve because they either can't get out of it or they have nothing better to do. Some of the questions and comments uttered during deliberations made me think these people had been viewing a totally different trial than the rest of us.
(2) If I'm innocent I want a judge - odds are he or she has a reasonable degree of intelligence..
