In daily life we seldom marvel at abilities such as grabbing a cup of coffee, recognizing a friend’s face, or jogging through a park. But these tasks are enormously challenging: we have to deal with overwhelming amounts of ambiguous and incomplete information entering our eyes and other senses. Why then don’t we always spill coffee, ignore our friends or crash into trees? There is growing evidence that to deal with these challenges the brain behaves much like a detective who makes smart inferences. The brain uses not only available sensory “evidence,” but also prior knowledge about the world to predict what the world should be like. The underlying principle is called

在日常生活中，我们很少会对自己的能力感到惊讶，比如能拿一杯咖啡，能认出朋友的脸，或者能在公园里慢跑。但这些任务具有巨大的挑战性：我们必须处理大量模糊和不完整的信息进入我们的眼睛和其他感官。那么，为什么我们不总是洒咖啡，忽视我们的朋友或撞到树上？越来越多的证据表明，为了应对这些挑战，大脑的行为就像一个侦探，做出聪明的推断。大脑不仅使用可用的感官“证据”，而且还使用关于世界的先验知识来预测世界应该是什么样的。其基本原则被称为
