I address that in the article. FIrst of all, so long as we buy the transitivity of the better than relation that won’t work. Second, it’s highly counterintuitive that the addition of extra good options makes an action worse.
I find it crazy and I think nearly all people do.
//This isn’t true. I can just deny the independence of irrelevant alternatives instead.//
That doesn’t help. The world where only button 1 is pressed is better than the world where neither is pressed, the world where both are pressed is better than the world where only button 1 is pressed, so by transitivity, an extra happy person is good.
You can always deny any intuition, but I’d hope this would convince people without fairly extreme views.
