Factfulness: The stress-reducing habit of only carrying opinions for which you have strong supporting facts.

When asked simple questions about global trends - why the world's population is increasing; how many young women go to school; how many of us live in poverty - we systematically get the answers wrong. So wrong that a chimpanzee choosing answers at random will consistently outguess journalists, Nobel laureates, and investment bankers.
In Factfulness, Professor of International Health and a man who can make data sing, Hans Rosling, together with his two long-time collaborators Anna and Ola, offers a radical new explanation of why this happens, and reveals the ten instincts that distort our perspective.
It turns out that the world, for all its imperfections, is in a much better state than we might think. But when we worry about everything all the time instead of embracing a worldview based on facts, we can lose our ability to focus on the things that threaten us most.

Inspiring and revelatory, filled with lively anecdotes and moving stories, Factfulness is an urgent and essential book that will change the way you see the world.

实事求是。只有在有强有力的事实支持的情况下才发表意见，这是一种减轻压力的习惯。

当被问及有关全球趋势的简单问题时--为什么世界人口在增加；有多少年轻女性去上学；我们有多少人生活在贫困中--我们的答案都是错误的。错得离谱，以至于一只随机选择答案的黑猩猩会一直比记者、诺贝尔奖获得者和投资银行家更有把握。

在《实事求是》中，国际卫生学教授、能让数据唱歌的汉斯-罗斯林与他的两位长期合作者安娜和奥拉一起，对为什么会发生这种情况提供了一个根本性的新解释，并揭示了扭曲我们观点的十种本能。

事实证明，这个世界，尽管有很多不完美的地方，但比我们想象的要好得多。但是，当我们总是担心一切，而不是接受基于事实的世界观时，我们会失去关注对我们威胁最大的事物的能力。

实事求是》是一本鼓舞人心的启示录，充满了生动的轶事和感人的故事，是一本紧迫而重要的书，将改变你看待世界的方式。
