Intelligence itself is not very well understood---much less its supposed "quotient." What in the world is a "quotient" of intelligence, as in "intelligence quotient"?
If I become Jeopardy grand champion, does that mean I'm "smart"? Or does it simply mean that I have trained myself to absorb vast quantities of "information,"---along the lines of the kinds of questions typically asked on the game show---and retrieve it quickly under stress of the bright lights, millions of viewers at home and hundreds in-studio, and so forth?
We would be talking about a mental athletic skill.
Remember the movie, "The Usual Suspects"? Remember that Kevin Spacey's character, the twisted cripple turned out to be Kaizer Sozhay. Remember what we learned about the yarn he told the detective? Remember where the information came from? The very office they were in. Remember?
Does that mean Kaizer Sozhay was "smart" (though he was smart) or a fantastic impromptu story-teller who can use absolutely anything to craft a narrative?---a handy skill to have if you are, say, a Hollywood screenwriter.
Surely this does not mean that people who cannot do that are necessarily "dumber" than him in any way. Some people are better at mental gymnastics than others---are more cognitively "athletic."
Look, Peyton Manning was not very athletic, yet he was one of the best ever quarterbacks and football players. Tim Tebow was a great athlete but not a very good quarterback/football player.
What I'm saying then, is let's be open to the possibility that "cognitive athleticism," if you will, is not synonymous with intelligence. That is to say, a good mental puzzle athlete may or may not also be a good thinker.
What I am saying is that, in my humble opinion, an IQ test is, at best, a level above "game show" recall, a test of "cognitive athleticism," which may or may not be related to your ability to "THINK."
Finally, if it is true that Mr. Trump has an IQ of 156 and Mrs. Clinton "only" has an IQ of 140, then all this means, in my view, is that Donald Trump is a better "cognitive athlete" than the Secretary of State; however, I suspect that like Peyton Manning, in corresponding terms, Mrs. Clinton is the better, shall we shay, "contemplative player," if that makes sense.
Thanks for the question.
