Understanding Cognitive Bias Found In Judgement & Choice
summary
Argues that reducing mean time to repair matters more than preventing every failure, cites Kahneman’s System 1/System 2 framework and shows concrete tests (the gorilla video where about half miss it, the F‑count where most see 3 but the correct answer is 3 vs 6 F's, Stroop slowing reading) and recommends practical mitigations: runbooks, game days/Chaos Monkey style drills, post‑mortems, measuring MTTR and tracking spikes to find where cognitive shortcuts and biases (hindsight, confirmation, normalcy) cause predictable errors.
