I know the defendants at Nuremberg were given IQ tests and scored fairly high, one as high as 142. They all praised Hitler’s intelligence and character. So has there been any attempts to analyze Hitler’s intelligence on any scale?
All people that have this amount of power need to be intelligent. There will be more than enough of people like voltures around people with so much power, waiting for the oportunity to take advantage of them. So if he really was the dictator who made the decision he had to be extremly intelligent. If he only was a good orator then decision made by him were not his decision.
