As the title of this post — Analysis of Text Jumbling and Legibility — demonstrates, jumbled text is not always as legible as is the widespread (mis)belief spurred by frequent mass mailings with texts like this:
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.
I found a very interesting web site that goes through a detailed discussion about the “Science of Word Jumbling”. Here’s the link.
At the bottom of this page is also another cool link to a site that lets you jumble your own text. It’s repeated here for easy reference.
