'Qwerty effect' causes people to prefer words written with letters on the right

'Our initial scepticism about the hypothesis of the effect raised our curiosity, it could be a good example of how human-computer interaction can have an fundamental effect on human communication,' Dr Garcia told MailOnline. 'We thought data from the web was a good opportunity to test the effect, and to our surprise we found evidence supporting its existence and illustrating some of its limitations.' The pair looked at millions of English-language product names and titles of books, films and video clips that appeared on 11 websites. The websites included Amazon, YouTube and Rotten Tomatoes. Dr David Garcia and Professor Markus Strohmaier wanted to see if the effect had any impact on the way we use words across the web.
