Fun Fact
Dogmatic is often used in politics, academia, or religion—anywhere someone clings to a belief system so tightly that opposing views are dismissed outright. It doesn’t necessarily mean the belief is wrong—just that it’s inflexibly held. In leadership or conversation, being called dogmatic is rarely a compliment; it suggests stubborn conviction without curiosity or tolerance.
