Test the principle of maximum entropy in constant sum 2×22×2 game: Evidence in experimental economics

By using laboratory experimental data, we test the uncertainty of strategy type in various competing environments with two-person constant sum 2×22×2 game in the social system. It firstly shows that, in these competing game environments, the outcome of humanʼs decision-making obeys the principle of the maximum entropy.

► Test the uncertainty in two-person constant sum games with experimental data.
► On game level, the constant sum game fits the principle of maximum entropy.
► On group level, all empirical entropy values are close to theoretical maxima.
► The results can be different for the games that are not constant sum game.
