为什么我们结构复杂的眼睛无法辨别简单的错觉？原来如此——问题在于我们的大脑。大脑虽然不断进化，但现在还只能应对自然的刺激。在 2012 年 TEDYouth 活动上，马克·长吉解释了大脑如何处理视觉错觉。

讲课：马克·长吉

The brain constantly tries to predict what will happen next, shaping perception in advance to keep up with a tenth-of-a-second delay. Even the simplest optical illusions fool our minds because they tap into processing built for survival in a fast-moving world. When parallel lines appear to bow or motion seems to blur, the brain is actually projecting what it expects to see in the immediate future. These illusions are not glitches, but signs of a brain fine-tuned for anticipation.
