That's how I felt. There is such thing as a personal moral code or system, and we can examine what happens to groups of people who are running various types and mixtures. We can try to determine which moral memes have the best outcomes, and are most likely to spread and be executed closely, and we can try to follow those codes.

Maybe that's pragmatic ethics, but the way morality is used in the survey implies that I'd believe in a single correct way of executing morality at the individual, day-to-day level. It's like asking whether I believe in being a carnivore, an herbivore, or a plant. The option "other" option is "morality doesn't exist," which is a bit like are you a) christian, b) jewish, c) muslim, or d) religion doesn't exist.
