Do experimental subjects favor their friends? Brañas Garza, Pablo Durán, Miguel Ángel Espinosa, María Paz Experimental procedures Friendship effect Dictator game Fairness deally we would like experimental subjects 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 these out-of-the-lab relationships by, for instance, randomly matching subjects. However, even if this type of procedure is used, it cannot be excluded that a subject may face a friend or an acquaintance.
