Replicator Dynamics (Fisher)
Winning strategies reproduce faster; adaptation speed rises with variation.
How it works
- Strategies reproduce in proportion to their payoff vs average.
- Winners grow, losers shrink — learning without brains.
- More variation today means faster adaptation tomorrow (Fisher).
Use → Learning systems, org routines. Protect variation to adapt faster.
Watch out → Starving variation in the name of efficiency, then freezing when worlds shift.
Try it → Track which meeting habits spread in your org — replicator live.

Diversity Prediction Theorem
Crowd error equals average error minus diversity. Diverse models beat the lone genius.
