Cass Sunstein

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.

Cass Sunstein is an American legal scholar born in 1954, widely regarded as one of the most cited law professors in the United States. A longtime faculty member at the University of Chicago and later Harvard Law School, he co-authored the influential book 'Nudge' with economist Richard Thaler. He served as Administrator of the White House Office of Information and Regulatory Affairs under President Barack Obama and received the Holberg Prize in 2018.
