I.Q. Tests (Rebroadcast)

By: Rebecca McInroy

We value brains. We hold test scores in high esteem. We spend money and hours on brain training games and ginseng. But what does intelligence really mean? How do we define and gauge actual smarts? Does a high IQ predict success?

In this episode of Two Guys on Your Head, Dr. Art Markman and Dr. Bob Duke talk about the history and development of intelligence tests; as well as what these tests can actually tell us about one’s ability to achieve.

It turns out that intelligence can be a dangerous label when thinking about the ongoing, dynamic, interconnected process that is our brain. Once we label something as intelligent we ignore that a lot goes into how we create, solve problems and overcome obstacles.

So next time you’re tempted (or forced) to take an intelligence test, don’t stress, they don’t tell the whole story of what you’re capable of.
