5. Decision Making > 47. Eliminate Dominated Strategies

Eliminate Dominated Strategies

Find your strongest strategy by systematically eliminating all of your weaker choices.

We’ve already seen that it’s important to find dominant strategies [Hack #46] when you make decisions, if possible. If you’re lucky enough to have a single dominant strategy, your choice is clear.

Sometimes, however, neither opponent has a dominant strategy. In that case, the opponents should try to eliminate strategies from consideration that are dominated and to continue eliminating weaker strategies until a single strategy emerges as clearly superior. When each opponent has settled on a single strategy, they have reached a pure strategy equilibrium, which is the best that either opponent can rationally hope for.1
