 This harnessing of the irrational for our own good is not paradoxical but it strikes some as problematic in the same way getting children to read by offering them financial incentives is problematic. We are getting them to read for the wrong reasons. At least in these cases there is the idea that once reading they will come to appreciate the pleasures and importance of reading for its own sake. But do people who stick with opt-in out of a tendency to stick with the given learn to change their faulty heuristic? If anything, it is reinforced because their faulty heuristic has a good consequence.
