 This vision of the good society rests on empirical assumptions that have been the subject of considerable debate. If it turns out that people systematically and predictably err in the pursuit of their interests, then it may be possible for governments to devise policies that correct for such  mistakes.[33]  Of course, government intervention can introduce other sorts of mistakes, and there is some debate about whether such measures are likely to do more harm than good (e.g., Glaeser 2006).
