In this article the most important issue of propagation and enjoining the good and forbidding the wrong, namely the issue of changing behavior and attitude, was investigated concerning religious literature and discourse and psychological analysis.
According to the findings of cognitive psychology, monitoring, and external command and prohibition, in addition to behavior regulation, is also very effective in the field of attitude formation. Also, contrary to the common understanding, even the establishment of laws and legal coercion about religious values can correct wrong cognitions and attitudes and make correct attitudes more stable and more effective in shaping behavior. Three diagrams in the text explain these facts.
Another result of this research includes the role of the cognitive theory of rational action (TRA) in explaining why many attitudes -in the matter of propagation- are not converted into behavioral intention and decision.
One of the most important deficiencies of the psychological means of propaganda is that religious propagandists- in promoting all values- limit themselves to building knowledge and eventually attitude and do not pay attention to metacognition and schematization.
