Gorilla Academy: Social influence on movie preferences

In this experiment, participants were asked to rate a series of movies on a scale of 0-100 using a slider. They also indicated how confident they were in that rating. The participants then see the film ratings from both critics and audience members. This information was taken from Rotten Tomatoes website and was correct as of December 2020. Using embedded data, the participant was shown their original rating and asked if they want to change it now that they have seen the other ratings.

The aim of this experiment was to investigate social influence and whether people were more influenced by expert opinion or public opinion.
