Have you encountered a situation that no matter how hard you try, there's still tons of typos slip away from your eyes? According to the scientist, it might be a really common situation, that there's even scientific proof for it.

When people write something, the brain is trying to express some kind of meaning, and this kind of action is viewed as an "high-class" function of our brain. Our brain tend to focus on meaning instead of wording, so we might have spelling errors because of this kind of ignorance.

Yet when we double check our own writing, we might not find out more typos as we thought. The reason why we can't find out more, is that we're too familiar with the article we wrote, and simultaneously, our brain focus on meaning more. Therefore, our brain "correct" the wording for us. This doesn't literally means we wrote things correctly, in fact, it means that our brain fix everything right in our brain, and accidentally cheat us that the wording of our article is correct.
