A major personal issue for Trump of course is the Dunning–Kruger
effect. As November draws closer, this will increasingly impinge on
his decision making abilities—in simple terms, he'll lose the plot.
His narcissism, smugness, and egomania will, thankfully, be his
downfall. He really believes he's a lot smarter than anybody else,
when in actuality he's never shown any capacity for advanced
intellect. He even had to lie about his phony degree from Penn's
Wharton—paid for by his older brother Frederick's money.
His oft-expressed pride in acing an Alzheimer's test was the classic
example of the man's stupidity LOL.
