New Book Summary: Inadequate Equilibria by Eliezer Yudkowsky


My latest summary is for Inadequate Equilibria: Where and How Civilizations Get Stuck, in which Eliezer Yudkowsky pushes back against what he calls "modest epistemology".

As usual, the key takeaways are below, and you can find the full summary by clicking the link above.

KEY TAKEAWAYS

  • Two competing views on when you should think you may be able to do something unusually well:
    • Inadequacy. We should understand how different systems work and the incentives within them to determine whether we’ll be able to outperform them.
    • Modesty. We should always defer to “experts” or “the crowd” because the average person will not be able to outperform them.
  • Inadequate systems are surprisingly common because of misaligned incentives and coordination problems. Even if someone spots an inadequacy, it’s usually inexploitable in terms of money or prestige, so the inadequacy does not get fixed.
  • Modest epistemology seems primarily motivated by social considerations:
    • It’s not necessarily arrogant to think you can outperform a system of experts on some dimensions. Systems can easily end up ‘dumber’ than the people within them. Rather than worrying about whether you are smarter or dumber in general, treat adequacy as a technical question where the answer shifts depending on the situation.
    • While correcting for overconfidence is good, underconfidence is just as big an epistemological error as overconfidence—just less of a social one.
    • People act to protect status hierarchies when they slap down those who try to “steal” status by attempting to do much better than normal.
  • But sometimes modesty seems to be based on misunderstandings of the following:
    • Applying base rates or the “outside view”. While Yudkowsky agrees this is a good idea, you can get reference class tennis when two sides disagree on which reference class to use.
    • Distrust of theories and models. The concern seems to be that people get too wedded to their theories and apply motivated reasoning to explain away all evidence that conflicts with it. But the answer there is to avoid motivated reasoning, not avoid theories and models.
  • It’s much easier to identify the correct contrarian experts in an existing field than to become one yourself.
  • Don’t overcorrect by falling into sloppy cynicism. The amount of failure to be explained is bounded.

This summary of The Book of Why: The New Science of Cause and Effect by Judea Pearl and Dana McKenzie explains how causal models can help us to better understand and control the world around us. This was a difficult one and I'm not sure how intelligible the key takeaways alone will be, as the diagrams are crucial to this book. Nevertheless, as usual I've set them out below and you can find the full summary (with diagrams) by clicking the link above. KEY TAKEAWAYS Statisticians woefully...

Joshua Waitzkin was a chess prodigy who won 8 National Championships before the age of 20. He later took up Tai Chi and became a world champion within 6 years. His book The Art of Learning is partly a memoir and partly a self-improvement book, explaining the principles that helped him succeed in disciplines as different as chess and martial arts. As usual, the key takeaways are below, and you can find the full summary by clicking the link above. KEY TAKEAWAYS Mastering the fundamentals will...

Hope you've had a good start to 2025. January's been a busier one with 2 book summaries and 4 blog posts: Book summaries The Art of Logic by Eugenia Cheng (28 mins) — explains how maths and logic work using real-world examples (and very few numbers). I found the sections on the limits of logic particularly useful. The Pyramid Principle by Barbara Minto (21 mins) — explains how to make non-fiction writing clearer by imposing a logical structure on it. So a rather logic-filled month with the...
