An Indiana University study has pulled, from the noise and muck of the stream, a statistically significant relationship between Twitter data and U.S. election results.
Specifically, the study found a correlation between the number of times a candidate for the House of Representatives was mentioned on Twitter in the months before an election and his or her performance in that election. The more a candidate is mentioned on Twitter, the better.
Previous studies have found a loose relationship between activity on Twitter and financial or political events. A 2010 study found that certain ways of analyzing Twitter could foretell a film's success at the box office better than a prediction market for that purpose.
