 In trying to argue against the aversive arousal reduction interpretation, Batson also manipulates the ease with which a subject can avoid helping another person (in this case taking his place when they see him getting electric shocks). He reasons that if empathy leads to genuinely altruistic motivations, subjects in the high empathy/easy escape condition should still be willing to help. If they were only helping in order to reduce their own negative feelings, they would be expected to leave in this situation, since leaving is the less costly means for reaching an egoistic goal. As Batson was happy to report, the results confirmed his empathy/sympathy-altruism hypothesis, not only in the above experiments but also in experiments testing other alternative interpretations of empathy such as the empathy- specific punishment and the empathy-specific award hypotheses.
