I think your scenario is good. I think the group dynamic and individual personality determine when this is easy and when it is difficult.
I have been in groups where it is easy to admit mistakes and move on; and I have been in groups where admitting a mistake feels like you are no longer part of the group.
So this can be realistic. I find taking the approach of admitting mistakes often helps others follow the same path, and leads to a better group dynamic.
