Now of course, there isn't just one language in the world, there are about 7,000 languages spoken around the world. And all the languages differ from one another in all kinds of ways. Some languages have different sounds, they have different vocabularies, and they also have different structures -- very importantly, different structures. That begs the question: Does the language we speak shape the way we think? Now, this is an ancient question. People have been speculating about this question for forever. Charlemagne, Holy Roman emperor, said, "To have a second language is to have a second soul" -- strong statement that language crafts reality. But on the other hand, Shakespeare has Juliet say, "What's in a name? A rose by any other name would smell as sweet." Well, that suggests that maybe language doesn't craft reality. These arguments have gone back and forth for thousands of years. But until recently, there hasn't been any data to help us decide either way. Recently, in my lab and other labs around the world, we've started doing research, and now we have actual scientific data to weigh in on this question. So let me tell you about some of my favorite examples. I'll start with an example from an Aboriginal community in Australia that I had the chance to work.

These are the Kuuk Thaayorre people. They live in Pormpuraaw at the very west edge of Cape York. What's cool about Kuuk Thaayorre is, in Kuuk Thaayorre, they don't use words like "left" and "right," and instead, everything is in cardinal directions: north, south, east and west. And when I say everything, I really mean everything. You would say something like, "Oh, there's an ant on your southwest leg." Or, "Move your cup to the north-northeast a little bit." In fact, the way that you say "hello" in Kuuk Thaayorre is you say, "Which way are you going?" And the answer should be, "North-northeast in the far distance. How about you?" So imagine as you're walking around your day, every person you greet, you have to report your heading direction. That would actually get you oriented pretty fast, right? Because you literally couldn't get past "hello," if you didn't know which way you were going. In fact, people who speak languages like this stay oriented really really well. They stay oriented better than we used to think humans could. We used to think that humans were worse than other creatures because of some biological excuse: "Oh, we don't have magnets in our beaks or in our scales." No; if your language and your culture trains you to do it, actually, you can do it. There are humans around the world who stay oriented really well.
