Effects of information on decisions were investigated. Questions addressed were: Does
different evaluation information affect decisions? Does familiarity with the object evaluated
moderate information effects? Does inputing information prior or subsequent to familiar
ization also moderate information effects? An educational film was shown to 204 graduate
students who were assigned randomly to no review or positive, negative, neutral, or mixed
review conditions. Some were given reviews only, while others were given reviews either
prior or subsequent to seeing the film. Information affected ratings and familiarity
moderated these affects. Timing alone had no effects.
