Not just nowadays, he's known since middle school how to tard cum the "helpless autist" act to get pity, dodge responsibilities, and weasel out of the consequences of his actions. It's so reflexive to him by now that he actually hedges and denies when he makes a positive statement about himself, because a competent person doesn't need pity and leniency.
So you'll often see him saying things like "I am smart... ... um, BUT I still suffer from my mental blanks and I have my flaws like everyone else because no one is perfect."
