 Finally, it is worth mentioning that the harm principle has also enjoyed more attention in public health ethics in recent years because some of Mill’s arguments have been subject to increased scrutiny. One of Mill’s arguments rests on the claim that others, including the State, are not as well-positioned to know the best interests of the individual as the individual herself, and the individual has the greatest interest in her own well-being. Accordingly, restricting the individual’s liberty for her own good will typically fail. Yet in recent years, some have drawn on findings in behavioral economics and social psychology to challenge this empirical claim about our self-knowledge, incentives, and competence at pursuing our own interests – and thereby challenge a claim that underlies the harm principle. This challenge can be specified in various ways. One specification is that we are quite bad at means-end reasoning due to ignorance; many would like to lead healthy lives but lack knowledge of nutrition. Another version of this is that individuals are bad at taking the requisite means to their ends due to various cognitive biases, such as temporal discounting, or lack of executive function. Individuals often know what is in their best interest, but they still succumb to temptation or otherwise act in ways that, arguably, are not conducive to what they as well as others appreciate is in their interest (Conly 2013, 2014; Hanna 2019; Sunstein 2013; Thaler and Sunstein 2003; 2008).
