Do you lose intelligence with age?

Scientists have long known that our ability to think quickly and recall information, also known as fluid intelligence, peaks around age 20 and then begins a slow decline.

At what age does IQ decline?

Now we can compare Full Scale (global) IQs for adults of different ages. A clear decline is evident. The mean WAIS-IV IQ is 100 for ages 20-24 and is 99 for ages 25-44. Then it drops to 97 for ages 45-54, to 94 for ages 55-64, to 90 for 65-69, to 86 for ages 70-74 and to 79 for ages 75+.

Does intelligence decline as age increases?

As age increases from about 20 years there is a gradual and continuous decline in intelligence test score. A wide variety of measures of intellectual ability has been employed, and while the rate of decline is less with some tests than with others, the downward trend uniformly is found.

What happens to a person's intelligence as they age?

Research Results

It has been shown that scores on IQ tests actually decrease with age. This chart shows how scores on Wechsler IQ tests peak between 25 and 29 years old, then decline throughout the rest of adulthood, with a decline becoming more steep after the age of 70.

At what age is your brain the sharpest?

What age is your mind the sharpest? The human brain attains peak processing power and memory around age 18. After studying how intelligence changes over time, scientists found that participants in their late teens had the highest performance.

What age does IQ stabilize?

The average child's IQ is not stable until around four years of age. It may be much later in children who were born early or who have significant health issues.

Is intelligence genetic?

General intelligence definitely runs in the family. Twin studies (on both identical twins and fraternal twins) have found a heritability of IQ between 57% and 73%, and in some cases, even higher. Interestingly, genetic studies have revealed that a child's IQ score is less affected by intelligence genes than an adult's.

Does reading make you smarter?

Not only does regular reading help make you smarter, but it can also actually increase your brainpower. Just like going for a jog exercises your cardiovascular system, reading regularly improves memory function by giving your brain a good workout.

Do IQ scores go down?

In most cases, IQ scores don't change dramatically unless there has been an unusual event (injury, trauma, etc.) When we see falling IQ test scores, we ask if this is due to the "Matthew Effect."
