Elrond Halfelven sounds like a real asshole
Elrond Halfelven—who decreed 39 years ago that his daughter Arwen ‘shall not be the bride of any Man less than the King of both Gondor and Arnor’—now departs Rivendell with Arwen for the two-month journey to Minas Tirith.

it's easy to think that academia is outdated, worthless etc but the fact that we are consistently the first targets for repression by dicators and wannabe dictators suggests we are still doing something useful and good for free societies despite our best efforts to fucking suck super bad

For eight days the Balrog has climbed secret tunnels with Gandalf in pursuit. Finally they reach the Endless Stair of many thousand steps, which brings them to Durin’s Tower and a narrow ledge atop Zirak-zigil. The Balrog bursts again into flame. The Battle of the Peak begins.

The area of Andorra is 470 square kilometers (180 square miles). To put it in perspective, the area of San Jose, CA is 180 square miles.
So Andorra is about 2.5 times bigger than Lichtenstein or DC.
Lichtenstein has about 40,000 people, Andorra has about 80,000.

Friends, this site has the juice.
I disagree here. The papers are interesting as @aleximas.bsky.social has pointed out (bsky.app/profile/alex...), but differences in elicitation producing preference reversals predates Prospect Theory. If you don't know Lichtenstein & Slovic (1971) and Grether and Plott (1979), read below.
These two papers, taken together, really cause a rethinking of behavioral economies.
Rather than having anomalous risk preferences; it looks like people have complexity aversion to "hard" decisions, especially on valuation, which drives behavioral anomalies. Herbert Simon ftw.
