Back way in history and pre-history, knowledge of yourself probably wasn't that important because people did what their parents and grandparents did, whether they were hunters or fishermen or crafts people. But nowadays, especially in a developed society, people lead their own lives. We follow our own careers. We often switch careers. We don't necessarily live at home as we get older. And if you don't have a good understanding of yourself, you are in big trouble. So that's intrapersonal intelligence.The eighth intelligence, which I added some years ago, is the naturalist intelligence.

Understanding Yourself

And if the parent came to me and said, well, should we supplement or should we accentuate? I would say, well, tell me what you'd like your child to do. Or better, let the child tell you what he or she wants to do rather than saying, well, science says you should do one or the other. I think it's a question of values, not of science.Some people think there's such a thing as humor intelligence, but in fact, I don't. I think humor intelligence is simply the operation of the logical intelligence in some realm like human nature or physical nature or the workplace.

Humor Intelligence

What does it mean to love? Why do we die? What's going to be in the future? My pet bird might have more musical intelligence. The rats that are scurrying around the floor might have more spatial intelligence, but no other animals have existential intelligence. Part of the human condition is to think about questions of existence.And I like to say every five year old has existential intelligence because five year olds are always asking, why this, why that? But the difference between a five year old and a philosopher, is the five year old doesn't pay too much attention to the answer.

Questions of Existence

And I say, well, why, if you're good with words, is that an intelligence, but if you're good with tones and rhythms and tambours ... and nobody's ever good me good answer. Which is why it makes sense to talk about musical intelligence. And in certain cultures over history, musical intelligence has been very important.A fourth intelligence is spatial intelligence. That's the intelligence which allows us to handle and work in space that's close by. A chess player would have spatial intelligence.

Spatial Intelligence

Whereas philosophers and other people who develop existential intelligence are really very interested in how we attack questions like that.So again, whether there's eight intelligences or 10 or 12 is less important to me than having broken the monopoly of a single intelligence, which labels you for all time. I think if we lived forever, we could probably develop each intelligence to a very high degree. But life's very short. And if you devote too much attention to one intelligence, you're not going to have much time to work on other kinds of intelligences.

Kinds of Intelligences

In this video interview, Dr. Gardner addresses his eight classifications for intelligence: linguistic, logical mathematical, musical, spatial, bodily kinesthetic, interpersonal, intrapersonal, and naturalist.Currently, I think there are eight intelligences that I'm very confident about, and a few more that I've been thinking about. And I'll share that with our audience. The first two intelligences are the ones which IQ tests and other kinds of standardized tests valorize. And as long as we know there are only two out of eight, it's perfectly fine to look at them.

A Video Interview

Now, you could have two people who have exactly the same expertise and knowledge in the field, but one is a very good teacher and the other isn't. That probably doesn't surprise individuals so much, but what got me fascinated was as young as two or three, kids already know how to teach.Now, what does that mean? You show a child how to do something, let's say a three or four year old, and then you ask the child to explain it to an older person or to a younger person.

Field Knowledge

And even the three or four year old will explain it very differently to a young person, will go through details and point things and speak slowly. And with an older person, they'll be much more elliptical and say, well, you do this and that and then you can figure it out. So that shows as young as three, let's say, we already have a teaching intelligence.The other one is one which I think is going to be difficult to prove to a skeptic, but I call it existential intelligence. And the existential intelligence is the intelligence of big questions, philosophical questions, artistic questions.

Existential Intelligence

And what happens is in humor, there's a certain expectation and you flip that expectation. So it's logic, but it's logic that's played out in different kinds of ways. People have mentioned there's such a thing as a cooking intelligence, a humor intelligence, and a sexual intelligence. And I quipped, well, they can't be intelligences, because I don't have any of them. -----Howard Gardner is a developmental psychologist and the John H. and Elisabeth A.

But another variety is being able to use your hands or other parts of your body to solve problems or make things. A craft person would have bodily-kinesthetic intelligence, even if they weren't particularly a good athlete or dancer. The sixth intelligence and seventh intelligence have to do with human beings. Interpersonal intelligence is how you understand other people. How you motivate them, how you lead them, how you work with them, how you cooperate with them. Anybody in any workplace with other people needs interpersonal intelligence.

Human Beings Intelligence

And that's the capacity to make important relevant discriminations in the world of nature. Between one plant and another, between one animal and another. It's the intelligence of the naturalist, the intelligence of Charles Darwin. I missed it the first go around when I wrote about it, but tried to atone by adding it to my list.And by the way, you might say, well nature isn't so important anymore. But in fact, everything we do in the commercial world uses our naturalist intelligence. Why do I buy this jacket rather than another one? This sweater rather another one?

The Intelligence of Charles Darwin

Leaders hopefully have a lot of interpersonal intelligence. But any intelligence can be used in a pernicious way. So we got the sales that sells you something you don't want for a price you don't want to pay. He or she has got personal intelligence, it's just not being used in a way that we might prefer.A seventh kind of intelligence is difficult to assess, but it's very important. It's intrapersonal intelligence. It's understanding yourself.

Intrapersonal Intelligence

One hairstyle rather than another? Those all make use of the naturalist intelligence, because the brain's very adaptive, and when an old use of a brain center no longer is relevant, it gets hijacked for something new. So we're all using our naturalist intelligence, even if we never walk out into the woods or into the savanna of East Asia.There are two other intelligences which I'm interested in. One of them is called the teaching or pedagogical intelligence, the intelligence which allows us to be able to teach successfully to other people.

Pedagogical Intelligence

Which are you? IQ tests only measure two of the eight intelligences. Howard Gardner explains.What does it mean when someone calls you smart? According to developmental psychologist Dr. Howard Gardner, it could mean one of eight things. Of the eight intelligences, only two are measured by IQ tests or other standardized tests. As Gardner states, “if you do well in those tests as long as you stay in school, you think you’re smart. But if you ever walk out into Broadway or the highway or into the woods or into a farm, you then find out that other intelligences are at least this important.”

Eight Classes of Intelligence

A surgeon would have spatial intelligence. But there's another variety of spatial intelligence, which we use for a much broader navigation. That's what an airplane pilot or a sea captain would have. How do you find your way around large territory and large space.Similarly, with the fifth intelligence, bodily-kinesthetic intelligence, it comes into flavors. One flavor is the ability to use your whole body to solve problems or to make things. And athletes and dancers would have that kind of bodily-kinesthetic intelligence.

Bodily-Kinesthetic Intelligence

And so the big question is, should you play to strength, or should you bolster weakness? And that's a value judgment. Scientist cannot give you an answer to that.If, for example, you want to be a Jack-of-all-trades and be very well rounded, then probably you're going to want to nurture the intelligences which aren't that strong. If on the other hand, you're dead set on really coming to the top of some particular heap, then you're probably going to find the intelligences that you're strongest at and really push those.

Jack-of-all-trades 

And if you do well in those tests, as long as you stay in school, you think you're smart. But if you ever walk out into Broadway or a highway or into the woods or into a farm, you then find out that other intelligences are at least as important. The third intelligence is musical intelligence. And that's the capacity to appreciate different kinds of musics, to produce the music by voice or by an instrument, or to conduct music. And people are going to say, well, music's a talent. It's not an intelligence.

Musical Intelligence

Linguistic intelligence is how well you're able to use language. It's a kind of skill that poets have, other kinds of writers. Journalists tend to have linguistic intelligence, orators. The second intelligence is logical mathematical intelligence. As the name implies, logicians, mathematicians, scientists have that kind of intelligence. They're able to do mathematical proofs. They're able to do scientific reasoning and experimentation. And it's great to have language and logical intelligence because most tests really focus on that.

Linguistic and Logical Intelligence

IQ tests only measure two of the eight intelligences. Howard Gardner explains them all.
