According to Festinger's minimal justification hypothesis, the best way to effect long-term attitude change is to persuade your subjects to change their behavior and their attitudes will follow.
Leon Festinger's theory
Cognitive Dissonance Theory (DCT) is a theory that explains the uncomfortable feelings that people have when they do something that is not in accordance with what they know, or have an opinion that is not in accordance with their own beliefs. This theory was discovered by Leon Festinger in 1957 and dissonance itself means imbalance, which is the opposite of consonance which means balance.
Dissonance can be said to be something unpleasant, so we generally try to avoid it. To avoid dissonance, we usually do the following:
-Ignoring views that are contrary to ours.
-Change our beliefs about something to match our actions.
-Looking for things that can reassure us after making difficult decisions, such as siding with things that are different from what we previously believed.
