The Nash Equilibrium
A Nash equilibrium is a set of choices where no one can do better by changing their move alone. Not where the game should end — where it will.
Picture rush hour. Everyone leaves at once, everyone sits in traffic, everyone hates it. Yet if you alone leave earlier, you lose sleep while the jam re-forms around everyone else.
That is an equilibrium: a resting point of mutual best responses. The game stops moving — not because anyone is happy, but because every one-person escape route is worse.
Stable is not the same as good. A team locked into pointless meetings, an industry into a price war: bad patterns outlive every complaint because unilateral change gets punished.

Ask who could improve alone
For any stuck pattern, test each player: could they do better by changing only their own move? If nobody can, you've found the equilibrium — and the reason it persists.
Stop attempting unilateral heroics
If you alone stop answering late-night emails while everyone else keeps sending them, you pay the price and the culture survives. Don't confuse martyrdom with strategy.
- Am I trying to solo-break a pattern that punishes soloists?
Move together or move the payoffs
Escaping a bad equilibrium takes a coordinated jump — a team-wide rule, a shared start date — or a payoff change that makes the new behavior individually worth it.
If a bad pattern keeps surviving, it isn't because nobody wants change. It's because nobody can change alone.
