đź“– Legal reasoning and political conflict
✍️ Cass R. Sunstein
đź—“ Published: 1996
New survey of Australian teenagers finds most did not comply with government's social media ban on under-16s. "Such bans are easy to circumvent, and being off a platform is individually costly when one’s peers remain on it." [Bursztyn, Sunstein et al. Cato research brief]
This paper argues that government lawyers have three core moral obligations: commitment to law enforcement, legality, and the rule of law. Warns that when government lawyers abandon these responsibilities, democratic governance is placed at risk. spkl.io/633207pAZp

Today is Constitution Day, recognizing the day in 1787 when the delegates to the Constitutional Convention officially signed the document. Learn more about its history, meaning, and impact from one of these great reads!
This paper by Cass Sunstein explores what it means to say the #Constitution is not "trapped in amber." Argues that constitutional interpretation inevitably relies on analogical reasoning & choices about the level of generality of constitutional principles. spkl.io/633207RUj4

Two minds better than one? Perhaps.
But there are many pitfalls preventing the many minds of a group reaching the correct conclusion, writes @casssunstein.bsky.social.
What could groups learn from prediction markets?
