Intelligence is actually incredibly hard to pin down with a solid definition. Academic success depends on the class, past knowledge, family situations, even who you sit by. IQ can only predict success to a certain degree, and it judges only how good people are at finding new patterns and solving problems. Some argue only looking at academic intelligence cuts out creative or practical intelligence. Emotional intelligence is a term for how well people know and understand their own and other’s emotions; it’s been shown to strongly predict interpersonal success. Even from culture to culture, intelligence can be seen as something focused around how you deal with people, or how you deal with information. It is multifaceted and the line between intelligence and talent is slimmer than most people realize.
However, we are obbsessed with intelligence. We want to believe it’s something you are naturally born with, that you can’t escape, but that’s not necessarily true. A person can actually raise their IQ to a certain degree, more effort can increase one’s grade and success in the workplace, and happiness isn’t even correlated with IQ! Pyschologists have been trying to pin it down for forever because it’s not as simple as “If you are intelligent, you will succeed in life.”
I have my own little theory about intelligence, and it is this: intelligence is how well a person can adapt and solve problems, while wisdom is how well a person can apply things they’ve learned to the “real world” ane real relationships. There’s overlap between the two. People have different amounts of each. It’s hard to judge something as complex as intelligence in something as small as a single number. When you go out and about your day, just remember that you can improve from wherever you’re at.
