“人类的大脑只开发了10%”——这一说法广为流传，许多人甚至对此深信不疑。然而事实果真如此吗？听古典音乐真的可以让人变聪明吗？下面5个关于人类大脑的传言其实都是假的。

1. A BIGGER BRAIN IS A BETTER BRAIN.

大脑越大越聪明。

Nope. After all, humans believe we’re the smartest animals on the planet, but elephant brains are three times larger than ours. And whale brains? Forget it.

并不是。毕竟，人类相信自己是地球上最聪明的动物，但大象的大脑比人类的大三倍。鲸鱼的大脑呢？不用说了。

Intelligence isn’t about relative size, either. Human brains make up about 2 percent of our body mass, which is pretty impressive. But tree shrew brains are a full 10 percent of their body mass, and they drink beer for a living.

智力也与大脑的相对大小无关。人脑约占人类体重的2%，这个占比已经很厉害了。但是树鼩的大脑相当于它们体重的10%，它们以喝啤酒为生。

So when it comes to brains, size isn't the most important thing. Hominid brain size did increase as we evolved, but scientists say that the secret to our smarts is complexity1. And nobody can beat us there; neuroscientist Gerard Edelman has even described the human brain as “the most complicated object in the universe.” Your cerebral2 cortex alone has betw
