/pol/ makes a million predictions a day, they'd be hard pressed to not make some correct ones every once in a while.
/pol/ can have a correct prediction every day, and it wouldn't mean /pol/ is right.
because /pol/ makes about a million wrong predictions for every right one they make. they just hang it up on the wall and shows anyone willing to glance, how they were right that one time.
a broken clock is right twice a day, if you keep making predictions over and over again at some point one of them is bound to be true purely on the laws of probability.
Yeah I took the question in terms of modern statistics. Unfortunately, I could find no concrete evidence about previous physician statistics. Still the fact that there are more doctors in the Cuban population than the Israeli make them the best Jews.
I saw a strange statistic once, but I am pretty sure it was out of context / wrong. Apparently Norway has more doctors per capita than hospital beds per capita.
