    "abstract": "Human behavior is one of the main problems for evolution, as it is often the\ncase that human actions are disadvantageous for the self and advantageous for\nother people. Behind this puzzle are our beliefs about rational behavior, based\non game theory. Here we show that by going beyond the standard game-theoretical\nconventions, apparently altruistic behavior can be understood as\nself-interested. We discuss in detail an example related to the so called\nUltimatum game and illustrate the appearance of altruistic behavior induced by\nfluctuations. In addition, we claim that in general settings, fluctuations play\na very relevant role, and we support this claim by considering a completely\ndifferent example, namely the Stag-Hunt game.",
