What is a dominant strategy
A dominant strategyis a strategy that leads to better outcomes for a player than other available strategies (while taking into account the strategies that other players can use). Dominant strategies can be strictly dominant or weakly dominant: 1. A strategy is strictly (or strongly) dominant if it leads to betteroutcomes than alternative strategies. 2. A strategy is weakly dominant if it leads to equal or betteroutcomes than alternative strategies. If a strategy is strictly dominant, then it...
Examples of dominant strategies
An example of a dominant strategy appears in a situation where you can either get $10 now, or you can flip a coin, and if it lands on heads then you get $10, but if it lands on tails then you get nothing. Here, the dominant strategy is to take the money upfront, since this will lead to an outcome that is as good as or better than flipping the coin, because you will either make as much money or make $10 more. Note that, in this example, the dominant strategy (taking the money upfront) is only...
What is a dominated strategy
A dominated strategyis a strategy that leads to worse outcomes for a player than other available strategies (while taking into account the strategies that other players can use). Dominated strategies can be strictly dominated or weakly dominated: 1. A strategy is strictly (or strongly) dominated if it leads to worseoutcomes than alternative strategies. 2. A strategy is weakly dominated if it leads to equal or worseoutcomes than alternative strategies. If a strategy is strictly dominated, then...

Example of strategic dominance
Consider a situation where two companies, called Startupo and Megacorp, are competing in a new market. This market has one product that is sold in two different versions: the consumer version and the professionalversion. Both versions are equally profitable for the company selling them, and the companies’ only concern is to make more money by selling more units. However, due to practical constraints, a company can only manufacture one type of product Most people in the market (80%) are intere...
Strategic dominance in single-player games
In scenarios where there is only one player, there can still be dominant and dominated strategies. For example, consider a situation where you are walking along a street, and you need to eventually cross the road. Just as you reach the first of two identical crosswalks that you can use, the crosswalk light turns red. You now have two strategies to choose from: 1. Wait for the light at this crosswalk to turn green. 2. Keep walking until you reach the next crosswalk, and then cross there. Given...
Games with no strategic dominance
There are situations where there is no strategic dominance, meaning that none of the available strategies are dominant or dominated. For example, in the game Rock, Paper, Scissors, each player can choose one of three possible moves, which lead to a win, a loss, or a draw with equal probability, depending on which move the other player makes: 1. Rock wins against scissors, loses against paper, and draws against rock. 2. Paper wins against rock, loses against scissors, and draws against paper....
There are several concepts that are often discussed in relation to strategic dominance. One such concept is strategy profile (also known as an action profile or a strategy combination), which is a specific combination of strategies undertaken by each player in a game. A notable type of strategy profile is the Nash equilibrium, which occurs when no ...
Strategic dominanceis a state in game theory that occurs when a strategy that a player can use leads to better outcomes for them than alternative strategies.A strategy is dominant if it leads to better outcomes than alternative strategies, and dominated if it leads to worse outcomes than alternative strategies.When deciding how to act, you should assess your available strategies, and then prefer to use dominant strategies and avoid dominated ones; you can potentially also insert some randomness into your...You can predict people’s behavior by expecting them to prefer to use dominant strategies and avoid dominated ones, but it’s important to account for factors that could interfere with this predictio...Why is a dominant strategy important? A dominant strategy is important because it simplifies the decision-making process for players. By identifying their dominant strategy, players can confidently choose the strategy that maximizes their own benefits without worrying about the actions of others.

When players recognize a dominant strategy, they are more likely to adopt it, leading to stable and predictable outcomes in competitive interactions. This understanding helps streamline choices and enhances the overall efficiency of strategic play.
Takeaways: Building a Language. Dominant Strategy: performs better than all other strategies, regardless of opponents’ behavior. Dominated Strategy: an alternative strategy always performs better, regardless of opponents’ behavior. Rationalizable Strategies: survive the iterated elimination of dominated strategies.
