Note: Behavioral Economics

I was listening to a podcast of David Fetherstonhaugh on "Behavioral Economics," in which someone asked how to find an overview of the history of the topic. He responded by saying that behavioral economics had come out of cognitive psychology, as it advanced from sensory input observations (at the time I studied it, to my constant disappointment) to the more complex variables of decision-making.
He said the best place to start was with the book, Nudge, by Thaler and Sunstein (2008), and work back from there.
The book is largely about "tricking people into doing what they ought," like, planning and saving for the future, by designing programs that ride on their natural inclinations in decision-making. While I would prefer a pro-active, reasoned, caring explanation of what I ought to do; here, in real life, is the more ad-hoc husbanding of [what people do] to [programs that will take care of these oughts]; they even use the term, "paternal libertarianism."
