Summary

American legal scholar and philosopher who co-developed nudge theory, has written on deliberative democracy, and was Administrator of the Office of Information and Regulatory Affairs under Obama.

Core Contribution

Nudge (with Thaler): libertarian paternalism — choice architects should structure decisions to nudge people toward better outcomes while preserving freedom. Republic.com: internet filter bubbles and the echo chamber problem for democratic deliberation. The Laws of Fear: a critique of the precautionary principle in environmental regulation.

Key Spikes & Highlights

  • Libertarian paternalism: preserve freedom of choice but arrange the choice architecture so that the default nudges people toward better decisions (opt-out rather than opt-in for pension savings). This is politically pragmatic and philosophically coherent.
  • Republic.com predicted social media filter bubbles in 2001 — before Facebook — arguing that personalized information environments would undermine the shared democratic information necessary for collective self-governance.
