There’s an internet rumor that I imagine most people are familiar with that usually goes something like this:
The phaonmneal pweor of the hmuan mnid, aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it denos’t mtater in waht oredr the ltetres in a wrod are, the olny iprnoatmt tihng is taht the frist and lsat ltteer be in the rghit pclae. The rset can be a taotl mses and you can sitll raed it wouthit a porbelm.
Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe. Amzanig huh?
At first glance it appears simultaneously counterintuitive and self-evident, which is always a fun experience. Sometime back in the day I read (probably on Language Log that the claim is somewhat misleading, and that properties of the English language generally and the sample paragraph specifically contribute significantly to the effect (rather than it being something wholly attributable to the way the mind processes text). The counter-claim says that because English (supposedly) has shorter words than many languages, and its writing system has explicit vowels, reading scrambled words is a lot easier than it would be in German or Hebrew. The other factor is that the sample paragraph itself is not a good representation, both because it contains shorter words than many styles of writing, and because the self-referentiality of the paragraph gives significant contextual clues.
I don’t know much about the truth value of the counter claims, since I was just pulling some heresay out of my long-term memory, but the latter part is definitely something we can test. I slapped together a quick javascript applet to help, so any old text can be pasted in and shuffled about.
Short words make reading scrambled text a lot easier, because any word with less than four letters remains in its unscrambled form, and all four letter words merely have two adjacent letters swapped. English has enough short germanic words that you can get away with most of your words being some six letters or less, which keeps all of the letters from straying very far from their correct locations. However, if you scramble the words in more formal writing that tends toward longer words, I think it starts to break down. I’ll go find the first two news stories that pop up on Google News and scramble their first paragraphs:

I think the first one is definitely harder, and it seems to have longer words as well, which I’m sure is most of the reason. I don’t know what the “rietrbh of pvigsssorriem” is, but now I’m definitely worried about it.
So go scramble some long-worded passages, show them to your friends, and convince them that not being able to read it indicates some kind of brain damage.
UPDATE: I’ve since come across a short video addressing this exact topic from a similar angle.
