So the CS must also provide useful, nonredundant, information about the occurenceo f the UCS

When behavior can be justified by means of external inducements, there is no need to change internal cognitions. However, when the external justification is minimal, you will reduce your dissonance by changing internal cognitions.
analogy of inoculation
William McGuire, resist persuasion. In physiological inoculation against disease, an active disease-producing organism, or pathogen, is injected into the body. This pathogen is in a weakened form or strain. In response, the body will ultimately develop a resistance to stronger forms of the pathogen.

However, when this is not possible, they compare them to those of other people. 2) the less the similarity of the opinions and abilities between two people the less the tendency to make these comparisons. 3) when a discrepency exists with respect to opinions and abilities, there is a tendency to change one's position so as to move it in line with the group. The need for self-evaluation becomes linked to the need to affiliate
