Sorry for answering a question with another question, but do you consider Hillary to be “brilliant” too ?
Alan Derschowitz, claims he is off the charts brilliant. "Without a doubt he is the smartest student I have ever had.... I've had great students, but he has to be at the top of anyone's short list in terms of raw brain power."
He has what's called an audio-graphic memory. He remembers everything he hears & said it's like an audio file in his brain just replaying. He remembers the inflection, everything. He also memorized the constitution when he was in sixth grade & still remembers it. He had a near perfect score on his LSAT as well, and his IQ is somewhere around 145.
In my opinion, all con men display a degree of brilliance even if that brilliance is limited to knowing how to use confidence effectively.
