I should be very, very clear.
We are a nation of 340 million people, of which at least half are old enough to be president, so 170 million people.
I think smart matters a lot. I think that the real drivers in this world were geniuses - Tesla, Einstein, Ford, Gates, Jobs, Westinghouse, Edison, Bezos, etc. We know that a number of those guys had IQs north of 140.
Now, there are a lot of people who were middling that also made a difference. I'm not saying you cannot make a difference - you obviously can do so....although I honestly am struggling to come up with a good example.
But here is the point - 2.2% of the population has an IQ above 130. That's 170 million people * 0.022 or 3.5 million people or so.
So, we have 3.5 million people to choose from that we know are really quite smart. Out of that 3.5 million people, there will be some who are otherwise unsuitable (bad actors, immature, no presence, too introverted, too weak). But in that 3.5 million, we can get 9 supreme court justices, a president, VP, and 100 senators.
Then on the judicial side, we'd have Ted Cruz debating the merits of the law with Alan Dershowitz. That knocks the hell out of Kamala Harris questioning Amy Coney Barrett.
On the legislative side, we'd have Thomas Massie debating....how about Elon Musk?
