Rationality, LW or otherwise, has nothing to say about "correctness" of terminal values.
Correctness is the property of a description that accords with the thing being described. When you ask, "What are my terminal values?", you are seeking just such a description. A belief about terminal values can be correct or incorrect when it reflects or doesn't reflect the terminal values themselves. This is not fundamentally different from a belief about yesterday's weather being correct or incorrect when it reflects the weather correctly or incorrectly. Of course, the weather itself can't be "correct" or "incorrect".
I've read through some of the Sequences, but I'm still unclear on a few basic concepts around LW rationality. This is in part to my learning still which benefits from social engagement (ie discussions) rather than just reading. One of those concepts I'm unclear on: Is there an inherent value to human (or sentient) life?
It appears to me that one common theme on this site is that human life (current and future) is very important. Why is that so? Why is the goal people over paper clips?
