Answer:
The attitudes-follow-behavior principle.
Step-by-step explanation:
The attitudes-follow-behavior principle: The attitude-follow-behavior principle is defined as an individual can't control his or her feelings directly yet he or she can influence the feelings by changing or altering a particular behavior.
According to this principle, the more an individual feels dissonance i.e, the conflicts between thoughts and behavior the more he or she is directed towards finding a consistency, for example, changing one's attitude or behavior to explain certain acts.
