Why not both useful beliefs and useful emotions?

Why privilege beliefs?

A useful belief is an accurate one. It is, however, easy to believe a belief is useful without testing its veracity. Therefore it is optimal to test for accuracy in beliefs, as opposed to querying one's belief in its usefulness.

Conversely, why not both accurate beliefs and emotions? Let useful come into play when choosing your actions. This can include framing your emotions - but if you just go around changing your emotions to whatever's useful, you're not being yourself.

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.)
