I’m not saying that a little more rationality wouldn’t be helpful. I’m saying the pointing to this and saying it’s irrational and maybe stupid is not the most interesting thing that can be said about it. It is more fascinating to look for what is incentivizing the irrationality.

There’s a very rational (in the sence of effective for getting what you want) negotiating tactic I heard about in one of Eric Flint’s books. The negotiator points at Crazy Joe muttering to himself in the corner and says ‘He and his friends are saying that if you don’t double their salaries they are not only going to strike, they’re going to be throwing rotten eggs at you come into the office and showing up at your house at midnight with bullhorns. But I know these people and can talk their language. I can get them to calm down. But you have to give me something in exchange. A ten percent raise doesn’t sound so crazy compared to double the salaries, does it? And besides, if you don’t make a deal with me, you’ll end up having to negotiate with Crazy Joe.’ And the business manager is so aghast by Crazy Joe’s demands that he ends up agreeing that ten percent is not as extreme as he first thought.

The fact that there is a crazy extreme getting a lot of attention, can make the only rationally extreme seem moderate. This sort of tactic doesn’t have to be disingenuous, or even conscious. In fact, If you eject (or steam roll into moderation) too many people for being more extreme than you are, not only do you weaken your negotiating position, you can get evaporative cooling in the direction of agreeing with your opponent.

Of course the people of the extreme extreme don’t need to know, and certainly can’t admit in public, that they are just being used to make other positions look good. When you combine that with the fact the SJWs have trouble coming to terms with the fact you can’t make everyone happy all of the time, the extreme extreme can spiral out of control in a way that is very hard to stop.

Nor is the basic tactic of preference statement counter productive on its own, if there is a significant enough presence of preference utilitarians in the audience to produce a reasonable hit rate. The problem is a coordination one where with enough people pursuing that strategy they end on having to be shriller and more negative to compete with one another. So they have to dwell on their misery, increasing its impact, and he audience gets bombarded. So even though everyone started out just wanting to create a little happiness actually end up creating a fair amount of unhappiness. And that's a much more complex problem solving situation then just pointing out that some people are being irrational.
