When I was just 9 years old, I was given a couple of IQ tests, one-on-one with actual psychologists, to gain admission to our school's program for gifted students.

Each of us in the program knew the minimum score to get in (top 2%), but few compared scores. It wasn't important, but I could tell which of my friends were a bit brighter.

Trump boasted about how much wealth he had, which--when it was finally revealed--was significantly lower than he had represented.

I expect that the same will be true of his IQ.

The end of this BBC article might allude to something by ending with "More on the US presidents", which I read "moron":

"Can we tell if Donald Trump has a high IQ?"
