How could it be otherwise? His confusion doesn't define his preference, and his preference doesn't set this particular form of confusion as being desirable. Maybe Wei Dai's post is a better way to communicate the distinction I'm making: A Master-Slave Model of Human Preferences (though it's different, the distinction is there as well).

See the example of the theist (above). Do you really think that the best possible outcome for him involves knowing more?

No, I think his values are defined in terms of a consistent ontology in which ignorance may result in a higher value outcome. If his values could not in fact be expresesd consistently then I do hold that (by definition) he doesn't lose by knowing more.
