The Accelerator/Brake model https://t.co/WBjlF3FBT1 It's usually worth decomposing interest in an activity into what drives you towards it (an accelerator) and what stops you (a brake). This model comes from the book "Come As You Are", where it's about sex, but is more general.

A book (or other document) is best thought of not as information conveyed, but a tool for thinking with, and the thoughts you have with it depend on both the book and on how you use it. https://t.co/lJg70WTx8g

We have a tendency to treat the world as more dependent on social reality than it is. Sometimes this works out well, but sometimes it ends up with us trying to argue with a volcano (or a pandemic), and that isn't the best of plans. https://t.co/FNrdDTwCrW

Predictions easily turn into norms: If a behaviour causes us to predict that someone is a bad person, people who want to be seen as good will avoid that behaviour, which accelerates the process. Often these behaviours are important, so this sucks. https://t.co/d1EaGQ5Wme

Perhaps the reason we punish some people who are being helpful is that we can tell full well that they're more interested in how their help looks than whether it helps, and the threat of punishment is incentive to consult the local experts before helping. https://t.co/MsPkMYFPxS

You don't have to read https://t.co/rTwKKf8IKx to understand this thread but it helps. TLDR: Hypothesis takes a random generator of stuff and gives you "test-case reduction" for it, which lets you ask it to generate things that are like that thing it gave you but smaller.
