What traits do they possess?
Hitler had the uncanny ability to commit precise details to memory, particularly historical information, technical facts, economic statistics, and past personal experiences.
Hitler also possessed the ability to adjust his conversation to the mentality of his audience. He could discuss highly technical matters with industrialists, engage in political conversations with diplomats, or simplify complex problems to a level easily understood by the common working class. Hitler used this talent to build his self-confidence by not allowing himself to feel intimidated when surrounded by those of a higher educational or cultural background and could comfortably discuss such topics as art, music, or literature. Hitler also used this skill when he wanted to persuade someone to accept his point of view. He always knew why a person wanted to see him before they arrived and had his counter-arguments so well prepared that the individual would leave convinced that Hitler's logic was sound and not unreasonable.
