Every single website will tell you to get to Bordeaux from London by going into Paris now again.

Markets can then aggregate preferences from a whole bunch of people who have come up with problems from a different angle. When you actually make choice uniform by didn't of forcing everybody to go through the same set of questions in the same order, do you actually make markets stupider?
