In future research, we have to search for mediator-variables that are not yet in the present study. On the ground of previous research (Berzonsky, 1990), we expect a positive correlation between Openness to Experience and Symbolic thinking. We also expect that this correlation is mediated by Information-Oriented Identity style, a concept derived from Berzonsky’s theory (1990). The partially found positively correlation between Agreeableness and Symbolic action in religion could be mediated by empathy. Furthermore, the relation between related concepts as Need for Closure and other factors in the present study has still to be examined as well. An other major concern in future research is to differentiate the results of the two personality factors Relativism and Second Naivité.
The universal-cultural status of the five personality factors has already been shown in previous research (McCrae, 1999), though it is not for the PCB and the correlations found with the five personality factors. Therefore future research has to be done in different kind of denominations and in different cultures.
