Scaling the critics: Uncovering the latent dimensions of movie criticism with an item response approach. Journal of the American Statistical Association.0003-12910162-1459http://nrs.harvard.edu/urn-3:HUL.InstRepos:3356140We study the critical opinions of expert movie reviewers as an item response problem. Building on earlier ‘unfolding’ models, we develop a framework that models an individual’s decision to approve or disapprove of an item. Using this approach, we are able to recover the locations of movies and ideal points of critics in the same multi-dimensional space. We demonstrate that a three dimensional model captures much of the variation in critical opinions. The first dimension signifies movie ‘quality’ while the other two connote the nature and sub ject matter of the films. We then demonstrate that the dimensions uncovered from our ‘utility threshold model’ are statistically significant predictors of a movie’s success, and are particularly useful in predicting the success of ‘independent’ films.en-USutility threshold modelfilmideal pointsJournal Article2009-10-28
