There isn't a single, perfect word to describe someone who always believes they are right, but several terms capture different aspects of this behavior:
- Infallible: This term suggests someone is incapable of making mistakes. It's often used in a religious context to describe the Pope or other figures.
- Cocksure: This describes someone who is overly confident in their own rightness, often to the point of being arrogant.
- Dogmatic: This refers to someone who rigidly adheres to their beliefs and refuses to consider alternative viewpoints.
- Self-righteous: This describes someone who feels morally superior to others and believes they are always in the right.
- Narcissist: A narcissist has an inflated sense of self-importance and a deep need for admiration. They often believe they are superior to others and struggle to acknowledge their mistakes.
- Ideologue: An ideologue is someone who fiercely believes in a particular ideology and often rejects any evidence that contradicts their beliefs.
It's important to note that these terms can be subjective and should be used with caution. Someone might be perceived as always being right, but they might simply be extremely confident or have a strong belief in their own abilities.
