This email story is still in circulation. However, as most email stories circulate, they began to mutate to some extent. The last time I received this story it was attributed to a Cambridge University researcher and read:
According to a researcher at Cambridge University, it doesn't matter in what order the letters in a word are, the only important thing is that the first and last letter be at the right place. The rest can be a total mess and you can still read it without a problem. This is because the human mind does not read every letter by itself but the word as a whole.
It really does work. The preceding paragraph, in jumbled letter format is:
Acocdrnig to a reschearer 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 a porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the wrod as a wlohe.
And I awlyas tghuhot slpeling was ipmtorant.
How would this affect people with dyslexia who already see words and numbers in a jumbled state?
