My Take

Cass Sunstein is one of the most productive and influential legal academics alive, and that prolific output is both his strength and the thing critics needle him about. 'Nudge,' co-written with Richard Thaler, pushed behavioral economics into real policymaking and reshaped how governments think about default options and choice architecture. I find him most interesting when he writes on cognitive biases, group polarization and how information cascades distort public debate, which feels more urgent than ever. He is not without controversy, but few scholars move so fluidly between abstract theory and the machinery of actual regulation. A genuine public intellectual.
