IBM's Watson analyzed all the 'Harry Potter' books and movies -- and the results are fascinating

You may know Watson for its ability to dominate Jeopardy, but did you know it has impressive movie skills too? IBM has hinted at Watson's movie-watching capabilities, like in its commercial with film director Ridley Scott, but we've never seen it in practice. So we asked Watson to tell us what it thought of the "Harry Potter" original book series and movies -- and the results are really interesting. By analyzing written text, Watson can identify different tones such as fear, joy, confidence, and openness. It can also analyze written text to assess personality traits based on the Big Five test, one of the most common, preferred ways psychologists use to measure personality.
