Another study from the University of British Columbia found that musical taste may also reflect social class. According to the authors, “Poorer, less-educated people tended to like country, disco, easy listening, golden oldies, heavy metal and rap. Meanwhile, their wealthier and better-educated counterparts preferred genres such as classical, blues, jazz, opera, choral, pop, reggae, rock, world and musical theatre.” Of course, what you hear growing up has a lot to do with your listening choices so it’s worth considering that this may have a lot more to do with nurture than nature.

But back to the Cambridge University study. The researchers divided people into three categories: Systemizers, Empathizers and equally balanced between the two. Systemizers tend to interact with others in a more logic-based way, while empathizers are more emotionally tuned in to those around them. And equally balanced speaks for itself.
