VOTING WITH YOUR TWEET: An experiment in political forecasting
This post was originally published by California News Service and was written by Mark Huberty.
Now that the election’s over, we can say a few things about how we did using Twitter to predict the winners.
First, we didn’t do so well. Using our predictions for what share of the vote Democratic candidates would earn, we predicted the winner about 75% of the time. That sounds good–after all each race has only 2 candidates, so maybe doing better than 50% accuracy isn’t so bad. But knowing races are usually biased towards the incumbent would have allowed us to predict correctly about 85% of the time.
