Twisted Incentives

I open by discussing, in great detail, a car accident my son was recently in. (Don't worry, he's okay.) I noticed that the story the other driver was telling had some inconsistencies. I'm suspicious because he has an incentive to lie, and from there I turn to a discussion of incentives more generally and bring in the recent hate crime hoax involving Jussie Smollett. And ask the more general question, are we focused too much on what people should do, and not enough what they might do, particularly if the incentive to do so is great enough.
