A taste of a postsecondary level moral philosophy class can turn you off of tasting meat. It’s been debated for thousands of years if learning moral philosophy actually changes how people live. Does knowing about the complexities of ethics actually make you more ethical? Short answer: yes. In a recent study a team of researchers and philosophers tested out if moral education about meat consumption would change their diet.
And it worked! Not only were students in the meat ethics sections likelier to say they thought eating factory-farmed meat is unethical, analysis of their dining cards — basically debit cards issued as part of UC Riverside’s meal plan that students can use to buy meals on campus — suggested that they bought less meat too. Fifty-two percent of dining card purchases for both the control and treatment groups were of meat products before the class. After the class, the treatment group’s percentage fell to 45 percent.
This effect wasn’t driven by a few students becoming vegetarians, but by all students buying slightly less meat. It’s possible this effect was temporary; the authors only had a few weeks of data. But it at least lasted for several weeks.
