Melanie Joy (born September 2, 1966) is an American social psychologist and author, primarily notable for coining and promulgating the term carnism.
[3] She has published the books Strategic Action for Animals, Why We Love Dogs, Eat Pigs, and Wear Cows and Beyond Beliefs.
[5][6] In a speech related by Indian cabinet minister Maneka Gandhi, Joy recalled how her dietary choice, made for non-moral reasons, transformed her perspective on the treatment of animals: That experience led me to swear off meat, which led me to become more open to information about animal agriculture—information that had been all around me but that I had been unwilling to see, so long as I was still invested in maintaining my current way of life.
[1] In a 2013 interview, she explained that her doctoral research had initially focused on the psychosociology of violence and discrimination, but later shifted to questions about the psychology of eating meat.
Perceiving a pattern of irrational and inconsistent thinking among the subjects she interviewed, she was led to theorize that attitudes about meat reflected acquired prejudice.
