Less Wrong views on morality?

Do you believe in an objective morality capable of being scientifically investigated (a la Sam Harris *or others*), or are you a moral nihilist/​relativist? There seems to be some division on this point. I would have thought Less Wrong to be well in the former camp.

Edit: There seems to be some confusion—when I say “an objective morality capable of being scientifically investigated (a la Sam Harris *or others*)”—I do NOT mean something like a “one true, universal, metaphysical morality for all mind-designs” like the Socratic/​Platonic Form of Good or any such nonsense. I just mean something in reality that’s mind-independent—in the sense that it is hard-wired, e.g. by evolution, and thus independent/​prior to any later knowledge or cognitive content—and thus can be investigated scientifically. It is a definite “is” from which we can make true “ought” statements relative to that “is”. See drethelin’s comment and my analysis of Clippy.
