你爱喝咖啡吗？你喝咖啡是因为纯粹爱它的味道呢？还是想借助咖啡帮你提神、集中精力呢？咖啡提神、醒脑的效果为大家所熟知，那么你知不知道咖啡除了可以让你提神醒脑、更精神以外还能让你更容易受他人影响哦！ Eighty percent of adults in the US and the UK are moderate users of the caffeine. 80%的美国人和英国人都在一定程度上是咖啡因的使用者。 Of all the effects it has on our minds—enhanced attention and vigilance—perhaps least known is its tendency to make us more susceptible to persuasion. 咖啡因的作用中，我们熟知的是它能让我们集中精神、提高警觉——但是很少人知道咖啡因能让我们更容易被人家说服。 Before the attempt to change their minds, half the participants were given moderate doses of caffeine, while the other half took a placebo. Both groups were double-blinded so that neither the researchers nor the participants knew who had taken what. Then they were given six stories to read which argued against euthanasia. 在实验开始前，参加实验的人员被分成两组，让其中一组人食用中度剂量的咖啡因，而另外一组则是安慰剂。这次试验是双盲实验，也就是说不论是研究者还是参与者都不知道参与者到底服用的是哪种物质。然后给实验参与者读6个关于反对安乐死的故事。 |
