Have you ever wondered what your tweets say about your politics? If you are an American Twitter user, log-in to our app below to see how how our model scores your tweets on a continuum from "very liberal" to "very conservative." To learn more about how we protect your privacy, visit this link.



Our model makes an estimate of the ideology of your tweets using machine learning. This model was created as follows. First, we collected public opinion data about the political views of a large group of Republicans and Democrats in the United States. Next, we asked those people for permission to collect the text of all public messages they've posted on Twitter. We then trained a model to predict the ideology of any user that learns from patterns in the groups of words Republicans and Democrats use in their tweets. Our final model was accurate at predicting the political orientation of 76% the people we studied.



Did your score surprise you? Though its possible that our model misclassified you, most people are unaware of how their political views compare to those of others-- particularly people in the other political party. To learn more about this phenomenon, often called "false polarization" check out Chapter Eight of Chris's book Breaking the Social Media Prism.



If you've just learned that other people might experience your political messages differently than you thought they would, think about what this means more broadly: maybe some of the people you thought were average members of the other party were actually extremists!

Can I measure the someone else's ideology?

Unfortunately, Twitter's policies only allow us to display this score for individual users themselves.

Why can't you do this for Facebook or other social media sites?

Unfortunately, Twitter is currently the only social media site that allows us to collect enough social media posts from people in order to estimate the strength of their political ideology.

What if I think my score is wrong?

Our model is just that-- a model. You may have heard the old saying "all models are wrong, but some are useful. Our model might be particularly wrong if you don't tweet about politics very often. Keep in mind that our tool only studies the text of any messages you produce, and not the accounts you follow or the tweets you like.
