From Matthew Baldwin's 'Tricks of the Trade' article:
Proofreader
If you’re reading too fast, your brain can “correct” typos, preventing you from catching them. That’s why it’s sometimes a good idea to read a page upside-down. It forces you to pay closer attention to individual words out of context, and you can’t race through pages too fast.
At his blog, Defective Yeti, Matthew has more to say on the subject.
