Dual-System Theory
System 1 is fast, automatic, intuitive; System 2 is slow, effortful, deliberate.
"Most decisions blamed on System 2 were quietly made by System 1."
What is Dual-System Theory? System 1 is fast, automatic, intuitive; System 2 is slow, effortful, deliberate. Strategy lives in System 2; execution and culture run on System 1.
You 'analyzed' the candidate. You decided in seven seconds and rationalized for forty minutes.
Strategy lives in System 2; execution and culture run on System 1.
Slow down high-stakes calls deliberately. Engineer System 1 cues for everything repeatable.
Use the model. Pick the move.
System 1 is fast, automatic, intuitive; System 2 is slow, effortful, deliberate. You've just seen this: You 'analyzed' the candidate. Which lever does the model recommend?
Pick a lever. There are no neutral ones — every incentive funds a behavior somewhere.
