Ergodicity
Average outcomes across the population differ from outcomes across time for one person.
"Russian roulette has a great expected value. Once."
What is Ergodicity? Average outcomes across the population differ from outcomes across time for one person. Don't confuse population statistics with personal survival.
Strategies with great averages that bankrupt individual players.
Don't confuse population statistics with personal survival.
Always ask: 'Can I survive each individual draw, not just the average?'
Use the model. Pick the move.
Average outcomes across the population differ from outcomes across time for one person. You've just seen this: Strategies with great averages that bankrupt individual players. Which lever does the model recommend?
Pick a lever. There are no neutral ones — every incentive funds a behavior somewhere.
