As for why people tend to prefer chocolate over vanilla and vice versa, apparently, there’s a genetic component.
Biotechnology company 23andMe said in a 2019 trait report that it could estimate the probable preference for either flavor. It examined 980,000 research participants, Food & Wine reported. Apparently, your preference may be narrowed down to your sense of smell. Additionally, women are more likely to favor chocolate over vanilla. Meanwhile, men are nearly evenly split. Vanilla is just barely ahead of chocolate.
