I wish there wasn't such a stigma around being proven wrong or being presented with new information, or just saying I don't know because it's just part of life, no one can be right all the time...sorry. If we didn't feel as much shame about it I think a great many things would change alot faster...
Normalize saying things like,
"I haven't thought of it like that."
"I hadn't seen it that way before."
"I must have misunderstood the first time."
"If I had known this information before, I wouldn't have thought like I did."
