Take 5 minutes to teach AI about emotions and help advance science. Tell us how you felt when writing your last three tweets.

This study is part of a MIT scientific research project. Assisting us takes less than five minutes. On the next page you will sign in with Twitter. Then you will rate how you felt when writing your three most recent tweets. We encourage people from all over the world to participate – your tweets do not have to be in English.


Your decision to complete this study is voluntary. Your answers will be analyzed in an anonymous form. Your name will not be shared by the researchers with anyone. The results of the research, including the content of particular tweets and your associated ratings, may be presented at scientific meetings, published in scientific journals or in other ways shared with the scientific community. Clicking on the ‘NEXT’ button indicates that you are at least 18 years of age and agree to complete this study voluntarily.
