> My brain auto-corrects a lot of obvious errors too. In grade school, when I would copy stuff off the blackboard, sometimes someone else would point out a mistake that the teacher had made. I would wonder why I, the consummate teachers' pet, hadn't caught the mistake. Then I would look at my notes, and see that I had written the text down correctly. My brain had corrected the mistake without even telling me about it.

Continuing this tangent, I seem to have a problem with numbers, but manage to do this auto-correcting anyway. Let's say I see the number 823 somewhere. When I look at it and mentally picture that number, sometimes I'll switch around two digits -- I might imagine 823 as 832. However, when I'm recalling that number either by saying the number or by writing it down, 823 comes out even though my mental picture of the number is wrong.

This only seems to happen with numbers for me, never words.
