From Ben Haller, Ithaca, New York, US
I enjoyed your look at “the hidden powers of gesture”. However, regarding the puzzle posed at the beginning – that people who listened to a debate between the US presidential nominees Richard Nixon and John F. Kennedy felt Nixon won it, whereas those who watched felt Kennedy won – there may be an explanation other than the power of gestures: Kennedy was far better-looking (19 August, p 34).
