Maybe not look at it like who was right or who was wrong, but rather who is responsible for what. Your responsibility is definitely to disclose any issues you believe may impede a project. If it's their responsibility, however, to reach a final decision, then, after you have voiced the new information, remember to respect whatever they decide. It's their ass on the line if it fails. You did your part. So, in general, never focus on who was right and who was wrong, rather focus on the common goal. PS Overly confident people are in reality typically really scared of being wrong. Be gentle ;)
