Many studies questioned the relationship between psychopathy and moral decision-making. Bartels and Pizarro (2011) found that the participants with higher subclinical psychopathic traits tend to endorse more to the utilitarian proposal. Does it mean that psychopathic patients would care more about the overall benefits of human beings than non-psychopathic people? Absolutely suspicious. Gawronski et al. (2017) developed CNI model to quantify the different mental processes when making moral decisions. The relationship between psychopathy and moral decision-making becomes hot topics and till now there are 4 studies probing into this relationship with CNI model. However, CNI model has its own deficits, which would result in inaccurate conclusions. Liu and Liao (2020) provided a new CAN algorithm to fix the limitations. Thus, we need to reanalyse the rawdata of the previous studies and correct the original conclusions.
