NEUROLOGIST DEBUNK 11 BRAIN
MYTHS
We don't know that for sure because it hasn't been fully studied. But we've seen that in instances such as chimpanzees, they do have smaller brains. What we do know for a fact is that chimpanzees are probably as smart as we are. Certainly, it's not the size of the brain that matters, but probably how complex it is and how well-developed certain areas are. Certain areas in humans, for example, our language centers, are just much more developed than a cow, even a chimpanzee. That's important in determining intelligence rather than the size itself. Also, how do we measure intelligence? That also becomes tricky because not everyone is intelligent in the same way. Non-cognitive factors also play a role, like what's your social intelligence? What's your emotional intelligence? All of that, I think, is very complex and really difficult to measure. IQ tests are not always an accurate measure of intelligence, so this is false. There's so much that goes into intelligence. Normal intelligence tests might measure things like executive function or planning, verbal skills, reading skills, things like that, but it's only an approximation of what you can do and highly influenced by the conditions of the test. How you're feeling at the time of the test, your educational level. It'll be nice to say that there's one test or one way that we can determine how intelligent someone is, but there's so much that goes into intelligence that one test or even multiple different tests can't measure that very well. So the popular IQ test was developed in the early 1900s, and it was a way to determine which French students were cognitively delayed so we could offer them better resources. That got adopted in America, at Stanford, where for all the reasons Brad laid out, it doesn't take all of those things into account. So I think, although it is nice to say, "Hey, I am smart, I did well on an IQ test," I don't really think that means too much. Neither of us were born being doctors, right? We had to learn and develop those skills under many years of training. I think that education is the best way to kind of make that happen. Education very broadly, that might not necessarily be school for everyone. Definitely. Some people are savants, some people are prodigies. It's really hard to say what determines that. They might be better at certain things, but not necessarily good at others. We're all individuals. We all have different talents and different aptitudes for different things. So IQ tests just kind of measure your intelligence in that one specific area, not how overall intelligent you are.
