all the nazi party members said that hitler was a genius, more intelligent than them, and to be honest that's kind of a necessity to lead successfully such a nest of snakes like the nsdap. the most intelligent nazis who were tested had numbers like 130-141 and almost all were a lot above the average iq. so hitler probably had an iq of 145-150. he probably wasn't more than that, because being too intelligent becomes soon a severe hindrance in social relations.
