The document discusses two books: "Nudge" which proposes influencing individual decisions through libertarian paternalism like default options and framing, and "Connected" which examines how social networks shape individuals and emergent properties arise from interactions. It provides examples of how behaviors like obesity, smoking and happiness can spread in social networks. Both approaches could inform policy, though "Connected" looks at influencing groups while "Nudge" focuses on individuals, and "Connected" may be more complex to apply due to unique network dynamics in different areas.
