Eliezer, it seems you are saying that all else equal a younger person is more likely to be right in a disagreement. This is why you feel comfortable disagreeing with "old-timers." But I'm guessing you don't apply that logic to people younger than yourself, that you have some other considerations that end up making your age the age near most likely to be right. I'll also guess that twenty years from now you will have found some other considerations that make that age near the best.
