What is intelligence?

Now that we’ve introduced the brain, let’s talk about intelligence or, more specifically, what makes you intelligent. Intelligence is a difficult term to define. It can mean different things to different people. In fact, the scientific community has been debating its meaning for a long time and there is still controversy over its exact definition and the ways to measure it. The “IQ” test was once regarded as the best way to measure intelligence.
However, there is now a general awareness of its shortcomings, namely, that it only tests specific branches of intelligence (see opposite). The important thing to bear in mind is that being intelligent is not only about excelling in a narrow academic field, or having a broad general knowledge, or even being good at spelling or math. All those things require a degree of intelligence but do not define intelligence. Rather, intelligence reflects a broader and deeper aptitude for understanding multiple things in one’s surroundings, for catching on, making sense of things, or figuring out what to do in any given circumstance. It’s about possessing the ability to analyze and evaluate, to imagine and invent, and, in practical terms, being able to apply and implement ideas successfully.
