But now, neuroscientists are directly measuring the neurons whose firing rates encode value and produce our choices. We know a lot more about the neuroscience of human motivation than you might think. Now we can peer directly into the black box of human motivation, and begin (dimly) to read our own source code
One observation: Robin Hanson is one of the founding intellects behind LessWrong and a frequent collaborator with Rationalist types, and he's cited several times here. But, he also wrote a book (with Kevin Simler) about how we are constantly lying to ourselves about our motivations.
**tl;dr** There is no ultimate goal. That may seem to imply nihilism, but it doesn't. This is fine, but in novel situations, I don't know what to do, because I don't know which goal to choose, because there is no ultimate goal.
It's somewhat unfair, but I think of Rationalists almost definitionally as those who are in deep denial of nebulosity
postrationalism seems to be an effort to re-introduce some nebulosity onto what is still a fundamentally rationalist framework.
. They aren't idiots about objectivity, the way the Ayn Rand cultists are, but they still think in terms of an objective reality and models that are more or less accurate – that's what LessWrong means. And look, above I was doing the same thing until I caught myself, so it's not like I'm immune.
