Perhaps a definition of "nudging" would help in this discussion. According to the Oxford Living Dictionary, to "nudge" is to prod someone gently to attract attention or coax or gently encourage someone to do something. Surely the identity of the nudger is relevant especially if he/she/it possesses coercive power. Having a friend "nudge" me to make a supposedly better decision is different from the state doing so. I can disregard my friend's advice but may not have this freedom with the state if the consequence means going to jail. Secondly, do we want to use "nudge" when we refer to laws (e.g. traffic or otherwise) aimed at ensuring we respect others' rights? If well founded, would we not want such laws to be stronger than gentle encouragement? Finally, if "humans are not very choosers", why should we assume that governments run by humans will choose better than ourselves? Would the "government nudgers" not themselves require nudging?
