I believe this will make many people stop and think for a minute. I know that I am fairly secure and set with my core beliefs. It would take a lot to shake those. Since they seem right, normal, logical and make so much sense to me, I may wrongly think that others agree with me. I would have never named it as a bias until I did the research. This bias is one that I definitely have probably need to make a greater effort to keep it in check.
Assuming that most people feel the same way as you can get you into some hot water. I don’t think I will say anything more until I take a good long look at myself.

Do you ever assume people agree with you?
