1) An oldie but a goodie: guess the correlation. 2) I really, really enjoyed this 80k episode on probability. One thing that stood out (and I’ll probably garble this) was the implication that the expected value of almost decision is infinite once you let infinities into the equation, because there’s always some non-zero probability of an event that produces infinite (or negative infinite) value. What if there is a God and will send you to hell if you eat celery? Very unlikely, but probably not literally a zero percent chance of being true.
