If you’ve ever used a word processor like Microsoft Word before, you’ve probably encountered the wonderful Autocorrect function. Autocorrect fixes some commonly made spelling errors as you type, which helps improve typing speed by reducing the need to manually correct those mistakes.
Interestingly enough, the human brain also has a built-in mechanism that catches these types of errors and mentally fixes them while they’re being read. Let’s take a look at this paragraph:
Aoccdrnig to a rscheearch at Cmabrigde 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 be at the rghit pclae. The rset can be a toatl mses and you can sitll raed it wouthit porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.
Weird, isn’t it? However, there are a few flaws in this argument.
According to the way the letters are supposed to be shuffled (the first and last letter of each word stays in the same position), words with three or fewer letters are unchanged. There are 32 words that are unaffected by the shuffling — that’s almost half the paragraph! Likewise, the shuffled four-letter words are easy to read because they can only be rearranged by swapping the middle two letters. For the remaining words, the rearrangements of the letters are fairly intuitive. For example, “porbelm” is only two letter switches away from “problem.”
Although it is true that we consider the entire word instead of just the individual letters when we read, the examples presented in the paragraph above are much too simple. Consider words like “Cgibramde” as opposed to “Cmabrigde” that was in the paragraph; a well-shuffled word is much harder to recognize.
What does this have to do with communicating science? Being able to be clearly understood is an important skill to have when it comes to sharing knowledge and information with others. While there is some truth with the “letter order doesn’t matter” argument (in the fact that the brain processes entire words at a time instead of letter-by-letter), a lot of it is just misleading science.
