![]() Of the five personality traits we measured, music taste is best able to detect Emotional Stability and Conscientiousness. Our results show that not only are personality traits able to be perceived using musical preferences, these results show greater performance than previous research that use reactions to musical excerpts and artist likes on social media to infer a person’s taste. To gain additional insight into these models, we measured correlations between each personality trait and the suite of metrics we constructed to represent what and how someone listens to. To understand how these personality scores relate to music preferences, we trained a machine learning model to predict someone’s personality using only their preferences and demographic information. We measured users’ listening habits, both what and how they listened to music, and compared it to their scores on a personality survey.Īlongside these measures, study participants were asked to complete the Big Five Inventory, a 44-item questionnaire measuring the Big Five personality traits: Openness, Conscientiousness, Extraversion, Agreeableness, and Emotional Stability. To get a more complete picture, we went beyond simple music taste to also look at how people listen to music: Do you discover new music or listen to old favorites? Are your tastes diverse? Do you have regular listening habits? By quantifying the answers to these questions we can build a more nuanced understanding. In agreement with best practices within social science, all users could additionally opt-out of the study at any time. We asked a number of Spotify users to opt into a study of their listening over three months, including information about the genres and moods of music that they listen to. Prior studies of music and personality run into limitations by rarely being able to fully measure listening habits, instead relying on self-reported preferences and small samples. However, by using more modern techniques and a broader understanding of music taste, we were able to show in a recent publication for Social Psychological and Personality Science that musical preferences can reflect the Big Five personality traits on par or better than prior big data personality studies. In fact, a recent meta-analysis seemed to cast doubt that the relationship was very strong at all. Yet until the early 21st century, there hadn’t been much study quantifying the relationship between personality and music preferences. Music, more than any other media, has strong ties to our emotions: music communicates emotion, stirs memory, affects mood, and spurs creativity. Music is such a core part of culture and everyday experience that it has long been believed to be connected to one’s personality.
