It's <i>about</i> backing that claim up:<p><i>"Fast forward now to 1936, when August Dvorak ... patented the Dvorak Simplified Keyboard...<p>The standard telling of [the Navy Study] story turns out to be false in almost every important respect....<p>[Dvorak et al] compared students of different ages and abilities (for example, students learning Dvorak in grades 7 and 8 at the University of Chicago Lab School were compared with students learning QWERTY in conventional high schools)...<p>Even in their studies, however, the evidence is mixed as to whether students learning Dvorak retain an advantage, since the differences seemed to diminish as training progressed."</i>
