Two physicists developed an algorithm to analyze Taylor Swift's emotions in each of her songs.
The analysis was published on April 1, and the paper is meant as a joke — but the science is real.
A total of nine hours, 43 minutes, and six seconds of music were analyzed by the pair.
Two physicists from the University of Chicago released an in-depth report on Thursday outlining an algorithm that they developed to analyze 149 Taylor Swift songs to decode the award-winning singer's emotions over the past 14 years.
The report, titled "I Knew You Were Trouble: Emotional Trends in the Repertoire of Taylor Swift," was published on arXiv, a prominent online repository for papers on math, science, and artificial intelligence. And despite the fact that it was released on April Fools' Day, the research and data that went into this paper are real.
