Others who have looked into this are in no doubt: "Am I wrong for thinking Hitler was a brilliant person who knew what he was doing ?
His estimated IQ is 140. I've looked over "Mein Kampf", his ability to reason and express himself demonstrates intelligence and considering his lack of formal education is impressive.
The people around him who did take an IQ test had IQs of 140 or better.
So he could be called brilliant. He made many mistakes many resulting from his damaged personality. He was distrustful and did not take advise from others but rather depended solely on his own deductions and intuition".
