Why edotirs and poorfrdeaers mghit msis a mspisleled wrod

For your edification, a curious study which piqued both my interest and humour. http://www.mrc-cbu.cam.ac.uk/~mattd/Cmabrigde/ Keep in mind, a lot of morphemes (or really long words) make a difference to how well this works. Also, the trick seems to apply to skilled readers, which I take to mean those readers who do now how to spell. Presumably, editors and proofreaders know how to spell. We hope. Quoting: In it Graham says: This reminds me of my PhD at Nottingham University (1976), which showed that randomising letters in the middle of words had little or no effect on the ability of skilled readers to understand the text. Indeed one rapid reader noticed only four or five errors in an A4 page of muddled text. So, proofreaders, editors: read slowly. Very. :D
