German born Wallisch is dedicated to understanding how lifestyle choices and perception play into our individual personalities. Now at New York University, he is currently developing a test that translates our preferences for certain musical patterns into a blueprint for our personality. By playing volunteers 50 or more short music clips and asking their opinion on each one, he can begin to see a trend in music preferences. According to Wallisch’s theory, this trend can then reveal certain personality types.

The end product will be an easy and reliable tool to help the users become more aware of the presence of those with psychopathic personality traits, whether in the workplace or on the online dating scene.
