What is Intelligence? (9 Types Controversy + Examples)

Are you intelligent?

Before you start to search for old IQ test results, let’s talk. The definition of “intelligence,” how it’s measured, and what it actually means to be “intelligent” may actually come as a surprise. Even the most important theories regarding intelligence, including Gardener’s nine types of intelligence, has been disputed by the world’s big names in psychology.

In this video, we’ll touch on the basics of what intelligence is, how it’s been defined in recent years, and where the theories of intelligence are moving. Let’s get started.

What Is Intelligence?

There are two ways that we can define intelligence - these two definitions are the root of the controversies regarding how to measure and identify intelligence.

The first definition is the one you are probably most familiar with: “Intelligence is the ability to acquire and apply knowledge and skills.”

The other definition is a little more complex: “Intelligence is the collection of information of military or political value.”

The second definition infers that intelligence is a measure of potential success throughout a community. This use for intelligence is what led psychologists to develop the IQ test.

IQ Tests And Intelligence

In the early 1900s, French psychologist Alfred Binet helped to developed the first type of intelligence tests. The French government wanted to use the test to determine which children were more likely to succeed in school and which children needed more help.

Binet’s original test measured the “mental age” of children based on the average age and skills of a group of students. He admitted that the test had limits and that a single number was not enough to accurately depict all of the factors that influence intelligence.

Still, the test was adapted to American schools and is still used to measure intelligence today. High IQ is still associated with overall job performance and life “success.” IQ can change over the span of a person’s lifetime. While it is very easy to decrease a person’s IQ, science is still looking for ways to “increase” a person’s IQ points.

Problems with IQ Tests: Intelligence and Speed

Unfortunately, even through many revisions of the standard IQ tests, there are still flaws in the design of the test. Let’s just look at one for right now.

Intelligence has a lot to do with “speed.” If I give you a complex problem on an IQ test, you might need a few minutes to solve it or a month to solve it. In both cases, you have the ability to solve the problem, but the person who can solve the problem more quickly will end up with the higher IQ score.

But what if you have learned how to solve the test before? The IQ test does take in your actual age, but other factors (including your education) aren’t necessarily taken into account. Remember, in both cases, the person learned how to solve the problem eventually, and when asked to solve the problem again, they could probably increase their speed. Does the IQ test accurately show how often people have had to solve related problems before the IQ test was administered?

Fluid Vs. Crystallized Intelligence

These questions have led people to explore different types of intelligence. How can we recognize people who take a little longer to learn something, but still have the ability to do so? How do we categorize people that just need to pull on past experiences to solve problems and repeat learned facts?

One of the ways we make these distinctions is by identifying fluid vs. crystallized intelligence. The theory of these types of intelligence was developed by Raymond Cattell, a psychologist who is also known for his work in trait psychology.

He theorized that there are two types of intelligence: fluid and crystallized intelligence.

Fluid intelligence is the ability to gather, store, and organize facts. Crystallized intelligence is factual knowledge. People can gain crystallized intelligence as they memorize new facts and are exposed to more knowledge. Fluid intelligence, on the other hand, is the ability to learn - and it decreases with age. Both types of intelligence, however, give you the ability to succeed.

Practical Intelligence and the Triarchic Theory

Another popular way of categorizing intelligence is the Triarchic Theory, developed by Robert J. Sternberg. Rather than looking at the way you gain and store knowledge, the Triarchic Theory looks at different ways that people apply knowledge.

Fun facts about animals or the ability to solve a logic puzzle may not help you when you’re trying to read a map or network, but all of these skills can help you succeed in certain situations. That’s what the Triarchic Theory aims to recognize.

They separate intelligence into three categories.

Analytical Intelligence is the type of intelligence we have been discussing. It is the brain’s ability to interpret information and use that information to solve problems. This is the type of knowledge that is required to gain a high IQ score, but the Triarchic Theory argues that there is more to intelligence than just solving a math problem. A lot of people call this type of intelligence “book smarts.”

Practical intelligence is “an experience-based accumulation of skills and explicit knowledge as well as the ability to apply that knowledge to solve everyday problems.” This is the type of intelligence that you need to solve the problems of the world around you. In order to gain practical intelligence, you need to have knowledge of the area, culture, history, the list goes on and on.

Math won’t help you solve a dispute between two neighbors or settle a debate on how to solve the city’s traffic problems. These are both great examples of practical intelligence. 

This type of intelligence is highly present in great leaders. In fact, Robert Sternberg said the definition of practical intelligence is to find the best fit between your personality strengths and the environment. 

Creative Intelligence is the last type of intelligence in the Triarchic Theory. It describes the ability to adapt your knowledge and gather relevant knowledge that will help you adapt to new situations. While practical intelligence is often referred to as “street smarts,” I would argue that this type of intelligence is more suited to be called “street smarts.” If you are dropped in the middle of an unknown street in an unknown culture, you’re going to need some creative intelligence to get where you need to go and adapt to the new situation.

Does this cover all types of intelligence? Not according to the last theory we are going to cover. We’ll wrap this video up with information about the nine types of intelligence.

Gardener’s Nine Types of Intelligence

You probably thought this was going to be a video about the different types of intelligence: musical, kinesthetic, linguistic...right?

The “nine types of intelligence” describes a theory created by Howard Gardener. Howard Gardener is an American developmental psychologist who studied different types of intelligence throughout the second half of the 20th century. He believed that IQ tests and traditional ways of measuring intelligence only addressed linguistic and mathematical intelligence. There are many intelligent people who, while they may not excel on a math test or a reading assignment, display a deep understanding and knowledge in other areas.

He explained seven different types of intelligence in his 1983 book, Frames of Mind: The Theory of Multiple Intelligences. Over the years, he’s added two other types of intelligence. While this theory is entirely separate from Kolb’s theories about different learning styles, we can connect the two and explore how people with different types of intelligence learn.

Gardener’s nine types of intelligence include:

  • Musical-Rhythmic
  • Visual-Spatial
  • Linguistic
  • Mathematical
  • Interpersonal
  • Intrapersonal
  • Existential
  • Naturalistic
  • Body Kinesthetic

Controversy With the Nine Types of Intelligence

The nine types of intelligence rocked the world of educational psychology. In recent years, this theory has been disputed. Jordan Peterson, arguably one of the most famous psychologists in the world today, calls the nine types of intelligence theory “rubbish.” He argues that the the nine types of “intelligence” are just nine types of talents.

These critiques and arguments are still in development. It will be interesting to see where the world of educational psychology and measuring intelligence moves within the next few decades. Keep an eye out for new developments, and remember - even if you never scored high on an IQ test, there’s still a good chance that you hold some type of intelligence that will help you succeed.

Types of Intelligence Tests

As we mentioned earlier in this personality psychology course, there are many different ways to measure aspects of personality. Most intelligence tests are designed in a way for the applicant to solve a problem and the reporter to observe and possibly time the applicant.
