Eliezer, what if psi phenomena are real, but they work through as-yet-unknown laws of physics? In this case reductionism could still be true (and probable), even if psi is real. I can’t really see why psi phenomena rule out a reductionist universe (and I guess Damien Broderick agrees...).
By the way, I don’t believe in psi, and think that all effects found thus far are based on the misapplication of statistics and related errors.
And there goes Caledonian making pointless arguments again… Couldn’t you pick a more frivolous objection?
