Describing a situation where they were clearly right and the other person was wrong, without acknowledging nuance.
Ignoring external factors like regulatory changes, competitor actions, or economic conditions.
Not demonstrating a willingness to compromise or consider alternative viewpoints.
Blaming the other party entirely without reflecting on their own role in the conflict.
