Eliezer writes, "In general, beliefs require evidence."

To which Peter replies, "In general? Which beliefs don't?"

Normative beliefs (beliefs about what should be) don't, IMHO. What would count as evidence for or against a normative belief?

In isolation, almost certainly nothing, but you can play normative beliefs against one another. If you can demonstrate that a person's normative belief is inconsistent with another of their normative beliefs, that demonstrates that one of them must be 'false'. You can't check them against reality directly, but they must still be consistent.
