A more thorough explanation:

Definition: Dogma is a belief or philosophy that is strongly held and considered to be authoritative. It is followed steadfastly, often to the exclusion of other approaches to the same subject matter. It can also refer to a formally stated and proclaimed doctrine of faith.

Examples:

• The belief that the earth is flat is a dogma held by some people, despite scientific evidence to the contrary.
• In some religions, there are dogmas that dictate how followers should behave and what they should believe.
• The idea that hard work is the key to success is a dogma that is often held by people in certain cultures.

These examples illustrate how dogma can be a belief or philosophy that is strongly held and followed, even if it goes against evidence or other approaches. It can also be a formal doctrine of faith that is proclaimed and followed by a religious group.
