(Gunshot.) Shhhh, just lie still, son, don’t try to talk. I know what you’re wondering. You come into town with the fastest draw in the West and I let you draw first and still you’re the one lying here with a bullet in ya. Well, if only you’d studied some neuroscience you’d know that being the fastest ain’t necessarily gonna help you, son. Why, a study just come out in the Proceedings of the Royal Society. That’s a Brit journal, don’t worry about it. Showed that I can go 10 percent faster reactin’ to you drawing your gun than if I just tried to draw my own gun first. Has to do with the way the nervous system’s set up. And that 10 percent, well more than made up for your puny advantage. They say the great physicist Neils Bohr wondered why the ones who drew second always seemed to win in Western movies. Well, now we know. Now gimme back my issue of Scientific American what you stole, you magazine rustler.


[The above text is an exact transcript of this podcast.]

 

Erratum: This transcript includes an error involving the allegedly "puny" advantage of gunfighter 1, whose advantage in fact is not puny. Although gunfighter 2 moves about 21 milliseconds faster than does gunfighter 1, the initiation of that movement can take about 200 milliseconds. So the faster reaction movement would not ordinarily make up for that delay. In this particular dramatic scenario, gunfighter 2 is simply the better shot.

(枪声)嘘嘘嘘,就在那别动,小子,别说话,我知道你在想什么。你是西部最快的拔抢手,我让你先拔枪,但你还是成了吃枪子躺地上的那个。小子,如果你学过些神经科学,你就该知道拔枪快并不一定有用。为什么呢?《英国皇家学会会刊》(Proceedings of the Royal Society)上就有相关研究,一本英国杂志,不过跟你已经没什么关系了。研究说你拔枪我作出反应,要比我自己先拔枪的反应快10%,这与神经系统的构建方式有关;而这10%,让我足以弥补你那微不足道的优势。据说,伟大的物理学家尼尔斯·玻尔(Neils Bohr)曾疑惑,为什么在西部电影中,第二个拔枪的人几乎总能赢。现在我们知道了。好了,现在把你偷的《科学美国人》(Scientific American)杂志还给我,你个小贼。


勘误:这篇文章存在一个错误,枪手1的所谓“微不足道”的优势实际上并非微不足道。尽管枪手2的动作速度会比枪手1快21毫秒,但枪手2的动作启动时间却需要约200毫秒。所以更快的反应通常不能弥补这个延迟时间。在这个特别戏剧化的场景中,枪手2只是枪法更准。
