Although the adoption of the Paris Agreement was in many ways a political triumph, seven years later many climate advocates are presenting the Paris target to judicial bodies as the de facto legal standard for fundamental rights protection in climate change cases. Yet, the history leading up to the signatories’ ultimate adoption of the Paris Agreement target suggests that the target is …

Modeling Through, Ryan Calo

Articles

Theorists of justice have long imagined a decision-maker capable of acting wisely in every circumstance. Policymakers seldom live up to this ideal. They face well-understood limits, including an inability to anticipate the societal impacts of state intervention along a range of dimensions and values. Policymakers cannot see around corners or address societal problems at their roots. When it comes to regulation and policy-setting, policymakers are often forced, in the memorable words of political economist Charles Lindblom, to “muddle through” as best they can.

Powerful new affordances, from supercomputing to artificial intelligence, have arisen in the decades since Lindblom’s 1959 article …
