Ideally we would like subjects of experiments to be perfect strangers so that the situation they face at the lab is not just part of a long run interaction. Unfortunately, it is not easy to reach those conditions and experimenters try to mitigate any effects from those out-of-the-lab relationships by, for instance, randomly matching subjects. However, even if this type of procedure is used, there is a positive probability that a subject may face a friend or an acquaintance. We find evidence that social proximity between subjects is irrelevant to experiment results in dictator games. Thus, although ideal conditions are not met, relations between subjects do not contaminate the results of experiments.

[Es] La teoría creacionista, universalmente en vigor antes de Darwin (y aún hoy sostenida por más de uno) sostenía que había habido una mente (divina), encargada de diseñar al hombre; que le puso ojos para que viera, oídos, mente para que pensara...Desde Darwin, por el contrario, se opina que la necesidad de enfrentarse a problemas diversos hizo que la mente fuera diversificándose, a través de sucesivas selecciones de las mentes más adaptativas. Según esto: 1.-¿Existen maquinarias biológicas “especializadas” en nuestro cerebro?. Y si existieran, 2.-¿Se desarrollan de forma espontánea?; es decir, sin esfuerzo ni instrucción formal? 3.-¿Se despliegan de forma inconsciente, autónoma y similar en todos los seres humanos? En definitiva: ¿Existe algo (facultad psicológica, órgano mental, sistema neurológico, módulo computacional…) que permita decir que las personas saben esto… o aquello… en el mismo sentido que las arañas saben tejer o los pájaros construir sus nidos?

Research on moral cleansing and moral self-licensing has introduced dynamic considerations in the theory of moral behavior. Past bad actions trigger negative feelings that make people more likely to engage in future moral behavior to offset them. Symmetrically, past good deeds favor a positive self-perception that creates licensing effects, leading people to engage in behavior that is less likely to be moral. In short, a deviation from a “normal state of being” is balanced with a subsequent action that compensates the prior behavior. We model the decision of an individual trying to reach the optimal level of moral self-worth over time and show that under certain conditions the optimal sequence of actions follows a regular pattern which combines good and bad actions. We conduct an economic experiment where subjects play a sequence of giving decisions (dictator games) to explore this phenomenon. We find that donation in the previous period affects present decisions and the sign is negative: participants’ behavior in every round is negatively correlated to what they did in the past. Hence donations over time seem to be the result of a regular pattern of self-regulation: moral licensing (being selfish after altruist) and cleansing (altruistic after selfish).
