You want accurate beliefs and useful emotions.

From a participant at the January CFAR workshop. I don't remember who. This struck me as an excellent description of what rationalists seek.

Why not both useful beliefs and useful emotions?

Why privilege beliefs?

This is addressed by several Sequence posts, e.g. Why truth? And..., Dark Side Epistemology, and Focus Your Uncertainty.

Beliefs shoulder the burden of having to reflect the territory, while emotions don't. (Although many people seem to have beliefs that could be secretly encoding heuristics that, if they thought about it, they could just be executing anyway, e.g. believing that people are nice could be secretly encoding a heuristic to be nice to people, which you could just do anyway. This is one kind of not-really-anticipation-controlling belief that doesn't seem to be addressed by the Sequences.)

"Beliefs shoulder the burden of having to reflect the territory, while emotions don't."

This is how I have come to think of beliefs. It's like refactoring code. You should do it when you spot regularities you can eke efficiency out of. But you should do this only if it does not make the code unwieldy or unnatural, and only if it does not make the code fragile. Beliefs should be the same thing. When your rules of thumb seem to respect some regularity in reality, I'm perfectly happy to call that "truth". So long as that does not break my tools.

"Beliefs shoulder the burden of having to reflect the territory, while emotions don't." Superb point that. And thanks for the links.
