Yes, I was thinking the same thing. Why would he not want the people to know he worked for the CIA or why is it not widely known he speaks 7 different languages. It would seem he would want to show off his intelligence if he was trying to prove himself to be a good candidate. But no, he keeps that shit secret so no-one will start looking in to his background and at the same time he can use his higher than average IQ to play mind games with the people.
