Bayesian Updating
Start with a prior; update with new evidence.
"Beliefs are bets you've placed. Update them when the table changes."
What is Bayesian Updating? Start with a prior; update with new evidence. Strategic posture that evolves with evidence instead of defending priors.
Updating sales forecasts as the quarter develops.
Strategic posture that evolves with evidence instead of defending priors.
Force documented prior + update on every major call.
Use the model. Pick the move.
Start with a prior; update with new evidence. You've just seen this: Updating sales forecasts as the quarter develops. Which lever does the model recommend?
Pick a lever. There are no neutral ones — every incentive funds a behavior somewhere.

When you encounter Bayesian Updating, your prefrontal cortex has to do extra work to override the automatic response — and that override budget is finite.
