Optimal gelaufen, einfach zufrieden oder unüberlegt gehandelt? Zur Theorie (un)eingeschränkt rationalen Entscheidens

How should we react to experiments that refute pure selfishness? Are deviations in action space only important if they imply considerable losses? For (un)bounded rationality it is unimportant which payoff declines lead to more or less adequate decision considerations. But also for unreflected actions a bad outcome need not necessarily arise if for example institutional frameworks exclude or restrict the exploitation of naïve agents. The comparison of rational and unreflected decisions is not reduced to action and payoff spaces, but extended to cognition space. The conceptual comparison is illustrated by results from laboratory experiments.
