Is there an innate human bias against admitting you are wrong or uncertain? During interactions with people, I've noticed that it seems like certain people have a habit of admitting uncertainty and a willingness to admit error. There doesn't appear to be a clear group that I could bucket them into (like scientists, conservatives, etc.), but these people seem to be a minority.

After thinking about why people might bias against admitting they were wrong, I couldn't come up with a good reason. It would almost seem better for an organism to admit a mistake and learn from others, than stick to something that might actually be wrong.

Is there an innate human bias against admitting you are wrong/uncertain? If so, has any research been done on why?
It's surely a combination of self-serving bias and avoiding cognitive dissonance. I'm not sure it there's a more specific name for it that has wide acceptance. It's been variously called "certainty bias", "feeling of certainty", "illusion of certainty" etc.
