                                According to Dr. Melanie Joy, the founder of the concept of carnism, the ideology is upheld by a specific set of defense mechanisms that prevent people from questioning their dietary choices. These mechanisms work to suppress the cognitive dissonance that arises when a person who values compassion participates in a system that causes animal harm.
