Gapminder asked the public in Sweden.
对瑞典公众进行了调查。
This is how they answered.
他们是这样回答的。
The Swedish public answered like this:
瑞典公众的回答是这样的。
Fifty percent thought it had doubled,38 percent said it's more or less the same,12 said it had halved.
50%的人认为翻倍了，38%的人认为没太大变化，12%的人认为减半了。
This is the best data from the disaster researchers,
对于灾害研究人员来说 这是最理想的数字。
and it goes up and down,and it goes to the Second World War,and after that it starts to fall and it keeps falling and it's down to much less than half.
然后上下有所浮动。然后到了二战之后就开始一路下滑，下降至远低于一半。
The world has been much, much more capable as the decades go by to protect people from this, you know.
这个世界相比数十年前而言在保护人们免受自然灾害方面的能力已经强了太多。
So only 12 percent of the Swedes know this.
只有12%的瑞典人知道这一点。
So I went to the zoo and I asked the chimps.
所以我去了趟动物园 问了黑猩猩同样的问题。
The chimps don't watch the evening news,so the chimps,they choose by random, so the Swedes answer worse than random.
黑猩猩才不看晚间新闻。所以它们是随机选择的 所以瑞典人的正确率还不如随机。
Now how did you do?
现在来看看你们做的怎样？
That's you.
这是你们的答案。
