But first, I should do a better job explaining personal epistemology.
Actually, that’s an almost perfect summary. I’ll add that to the end.
TL;DR: It’s looking like people need to be relativists before they can be right; relativism isn’t great, though; people need to move forward from relativism rather than retreat back into absolutism.
** I am asserting that it is true. This assertion is based on—well, on everything, really—but I want to make clear that psychology can’t really tell us much about epistemology in the philosophical sense; the job here is to determine what beliefs people do have about knowledge, not which beliefs are true. However, it seems pretty clear, philosophically, that knowledge is uncertain and constructed, that reality cannot be directly accessed, and so on.
*** The other focus for Less Wrong (and Slate Star Codex?) is the creation of a robot-god which will usher in a utilitarian paradise (and prevent the otherwise-inevitable rise of a robot-demiurge), so I’m still not sure what to make about their claim to reasonableness.
