Scrambled Spelling: Does It Matter?

Almost everyone has seen the following so-called discovery about English:

Aoccdrnig to rscheearch at an Elingsh uinervtisy, it deosn't mttaer in waht oredr the ltteers in a wrod are, the olny iprmoetnt tihng is taht the frist and lsat ltteer is at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae we do not raed ervey lteter by itslef but the wrod as a wlohe.

This so-called discovery has primarily been used by spammers to evade software that detects words that signal spam.

As an excuse for misspelling English, it is invalid.

First, all the words shorter than four letters must be spelled correctly.

Second, the message must be simple and contain familiar words. The message above further compensates for its misspellings because the message's content is echoed in the message's form.

Third, and most importantly, you will notice that these misspellings are carefully structured. For example, "Aoccdrnig" keeps far more of the basic structure of the word than, say "Anircocdg" would have. "Rscheearch" is a very disciplined misspelling compared to "rrhcscaeeh."

Finally, no one who wishes to be taken seriously scrambles letters or misspells words deliberately. Correct spelling is still a mark of both courtesy and prestige.

Here's what I think would be really interesting research: Just which misspellings are easier to overlook? The ones that retain the silhouette of the word? The ones that keep three to five final letters in their appropriate spaces, as "rscheearch" does? Or the ones that never move a letter more than two spaces, as "Aoccdrnig" does? In short, how DO we recognize a word? And do our recognition patterns depend on our individual learning styles?
