If I decide that Iraq has weapons of mass destruction because I like the team that says so, I'm still wrong. If I decide that Nickelback is entertaining to me because people around me say the same thing, I become correct.

I don't have high hopes for CEV, but I hope that humans at least converge on the obviously correct preferences to avoid hot pockets and Nickelback whenever possible.

(I think I became slightly infamous at Benton house for insisting that certain preferences could be objectively correct under any reasonable amount of reflection. This was mostly because something deep down in the core of my being knows that liking hot pockets just has to be fundamentally irrational. This is indicative of the depth of most of my philosophical intuitions.)
