Abstract
Using the parallel concepts and methods on the granular rod's spontaneous motion (PRL 106, 118001, 2011 [1]), in the observable (relative angular momentum) of the laboratory social evolution processes around the Nash equilibrium in the strategy space, we evaluate the large-deviation function (LDF) and its symmetry properties. The data comes from 19 laboratory random matching repeated two-population 2 × 2 experimental economics games with different payoff matrix and population sizes. Main result is: in the stochastic evolutionary processes of the laboratory population games, on the symmetry properties of the LDF, the social and the natural systems are of indifferent.
