A clear reason for the justification; you don"t like your friends dress, but she just altered it so you tell her you like it. The reduction of dissonance by changing something about oneself; one"s attitude or behavior: counter-attitudinal advocacy. Stating an opinion or attitude that runs counter to one"s private belief or attitude: festinger and carlsmith (1959) Cover story: the effect of interest instructions on performance on a boring task.
