Using Substition to Make Decisions Simpler

About this episode

There's a cognitive trick our brains play whenever we face a hard question or a difficult decision: we quietly swap the hard thing for something easier to answer. It's called substitution, and we do it constantly — usually without noticing, and sometimes to our detriment. In today's episode, I make the case that you can take this same shortcut your brain already runs automatically and start using it intentionally to break decision paralysis and get moving. • The Substitution Heuristic: Understand the mental move at the heart of this episode — when "How are you?" becomes "Is there anything I urgently need to say?", your brain isn't being lazy, it's compressing. It runs a quick calculation: what's the downside of the substitute? Usually it's low, so the shortcut holds. • Code Review as Substitution: See why you almost never review a big PR line by line. "Was it tested? Does it follow our best practices? Does anything look obviously wrong?" are all stand-ins for the harder, mostly-unnecessary work of reading every line — and most of the time, they're enough. • Performance Reviews Are a Best Guess: Recognize that your rubrics, metrics, and frameworks are themselves substitutes.
