A portion of the participants was aware of the negative traits their partner possessed; however, the remaining participants were unaware. Cooper hypothesized that if the participants knew about their negative partner beforehand, they would have cognitive dissonance; however, he also believed that the participants would be inclined to attempt to like their partners in an attempt to reduce this dissonance.<ref name=":12" />  The study shows that personal choice has the power to predict attitude changes.<ref name=":02" />
