Have people state their opinions on various questions, and then ask them how they would update if they encountered certain kinds of evidence. For example, a person who thought that European swallows had a higher airspeed velocity than African swallows might precommit to updating his belief to “undecided” if he was presented with evidence suggesting that African birds were generally faster the European ones. The group would then go looking after such evidence.
