School majors

General observations are easily dismissed as anecdotal but that doesn't preclude me from making one. When I was in school, I noticed that the morning classes were preferred by those studying science, business and math while afternoon classes were preferred by arts and fine arts students. This difference was also noticeable when it comes to being liberal or conservative with the liberals tending toward arts. That also represented the line between income after graduation. Now in high schools where mask are voluntary the teachers in English and social studies are more likely to wear masks than those in science and math. Is there also a difference in the politics of these two groups?
