I don’t even get the comparison.
For one thing, Adams was not correct; he predicted Trump would win in a landslide. He was “Running unopposed,” according to Adams. Trump did not win in a landslide.
For another, Silver didn’t start predicting things just with the 2016 race; he’s been doing this for years, across a multitude of elections, and his track record is excellent. Adams just got one prediction - well, actually, he didn’t get it entirely right. Sort of right. (I should point out he’d actually made quite a lot of definitive predictions when it comes to politics, and has been wrong about most of them, including his famed prediction that by August 2017 it would be embarrassing to not be a Trump supporter because Trump will have been amazingly successful.)
This is been gone over again and again, but no, it does not prove the model is wrong. I realize this sort of thing can be difficult to understand at first glance but if you do think about it it’s not THAT hard.
Suppose a good baseball player steps up to the bat, and you ask me, “Is this guy going to hot a home run?” As a FANTASTIC home run hitter will hit a homer 7, 8 percent of the time, so the correct answer is “Probably not. He’s likelier to hit one than most guys. A homer here is as likely as it ever is. Still, probably won’t happen.” IF he’s up against a shitty pitcher maybe it’s a 10 percent chance, so I tell you it’s 10 percent likely.
Then the guy hits a homer. Now, if you start crowing how wrong I was, I have to tell you, I’m going to think you’re a pretty big idiot. I didn’t day he WASN’T going to hit a homer - and had I said that and he grounded out, it still would have been a stupid prediction. The correct answer to a question like that is always “Maybe, and here is the approximate chance.”
I’ll tell you what; from now on let’s bet money. You bet in accordance with Scott Adams’s predictions and I’ll bet according to 538, and we’ll see who makes money.
I think Adams made some good points about elements of political marketing; his observation that Trump’s simple, repetitive, absolutely relentless approach was a much better one than people were giving him credit for was absolutely correct. But he’s quite wrong about a lot of things, and it’s plain in the text of his blog, which is becoming increasingly partisan and divorced from an objective assessment of reality.
