“One legend swirls more persistently around the QWERTY design than all others: how its inventor developed the arrangement to slow down typists. This is correct, as far as it goes, but it focuses on the wrong thing. Given the limits of nineteenth-century technology and the need for a complex scheme to actuate a series of metallic keys to strike a page, a major problem was developing a system where the keys didn’t jam. The time it took to clear key jams was the real bane of speedy typists, so QWERTY was an excellent compromise between an efficient key arrangement for people’s fingers and the need for a typing apparatus to whirl and clack. The QWERTY layout actually helped people type faster.4”
