The best way to overcome the “I know best” mentality of many people is to question the knowledge on which the other person’s opinion was founded.

say what the other person did, tell them what its impact was on you, and explain your assumption about their intentions, taking care to label it as a hypothesis that you are checking rather than asserting to be true.

Check for distortions. Spend some quiet time weighing their attack on your judgment or arrogance against other information you have about yourself. Check for denial. In what ways is what they are saying true? Check for exaggerations. What is the worst that could happen here? And what might you do right now to turn the conversation around?
