People may behave differently in a shared physical context due to the mere presence of others. The study examined whether individual moral judgments were subject to the confederate's presence. Experiment 1 supported the hypothesis that the confederate's presence, relative to the control group, increased deontological judgment, disapproving of sacrificing a person's lifetime or interest for preserving the greater good of others. Experiment 2 investigated whether the results extend to mental space. The result revealed that simulating a positive interaction with the confederate significantly increased the preference for deontological judgments relative to the control group. However, the effect disappeared if the participants were required to simulate only the person from the scenario that did not include any additional background contexts. These results demonstrated that the confederate's physical presence and simulated confederate's presence always preferred deontological judgments over utilitarian judgments. The findings suggested that the asymmetric moral effect occurred in the physical realm and mental space.
