Cass Sunstein

132.争论与说服：我们为什么吵架，怎么才算赢？ adds Sunstein as the group-polarization reference in the show’s belief-change branch. The episode uses Group Polarization / 群体极化 to explain why like-minded groups can become more extreme over time, especially inside information cocoons where status and loyalty shift the local center.

Cass Sunstein is the legal scholar whose 《弹劾》 supplies the main framework for 173.弹劾：如何罢免一位总统. The episode introduces him as a highly cited law professor with government advisory and regulatory experience, then uses his view to separate presidential impeachment from ordinary criminal punishment or partisan rejection.

The source’s Sunstein is a cautious constitutional thinker. He accepts that impeachment must be available when a president abuses power, betrays public trust, or damages the constitutional order, but he resists turning it into a flexible tool for punishing bad policy, general unfitness, ordinary illegality, or dislike of a president.

Source Position

• Sunstein’s central claim in the episode is that impeachment repairs the constitutional system rather than punishing bad people.
• His view keeps High Crimes And Misdemeanors tied to office abuse, public trust, and constitutional order.
• The episode connects his caution about impeachment to a broader reluctance to smuggle constitutional change through loose interpretation.
• His prior work on limited rationality and “nudge” policy is used to characterize his general preference for institutionally cautious design.

Connections

• Bill Clinton, Andrew Johnson, Richard Nixon, and Donald Trump - cases used in the episode to test the framework.
