[Music] but ten years ago I took on the task to teach global development to Swedish undergraduate students that was after having spent about 20 years together with African institutions studying hunger
[音乐] 但十年前,我接手了一项任务:向瑞典本科生讲授全球发展课程。那是在我与非洲机构合作研究饥饿问题约二十年后发生的。
in Africa so I was sort of expected to know a little about the world and I started in our medical university Karolinska Institute an undergraduate course called global health but when
在非洲,所以我被期望对世界有些了解,于是我在卡罗林斯卡医学院开设了一门名为“全球健康”的本科课程,但是……
you get that opportunity you get a little nervous I thought these students coming to us actually have the highest grade you can get in Swedish college system so I thought maybe
当你获得这样的机会时,你会感到有点紧张。我想这些来到我们这里的学生,在瑞典的大学体系中成绩都是顶尖的,所以我想也许……
they know everything I'm going to teach them about so I did a pretest when they came and one of the question from which I learned a lot was this one which
他们可能知道我要教给他们的一切。于是我做了一个预测试,其中有一个问题让我学到了很多:这五组国家中,哪一组的儿童死亡率最高?

这意味着差异之大远超数据的不确定性。我不打算在这里考你们,但答案是土耳其,其死亡率很高,其次是波兰、俄罗斯、巴基斯坦和南非。

I was compiling the report I really realized my discovery I have shown that Swedish top students know statistically significantly less about the world than the chimpanzees because the chimpanzee would score
正在整理报告时,我真的意识到了我的发现:我已证明,瑞典顶尖学生关于世界的知识在统计上显著少于黑猩猩,因为如果给黑猩猩两个香蕉作为奖励,让它从斯里兰卡和土耳其中选一个,它也能答对一半的情况。
half right if I gave him two bananas with Sri Lanka and Turkey they would be right half of the cases but the students are not there the problem for me was
但学生们并没有达到那个水平。对我来说,问题不在于无知,而在于先入为主的观念。
