IQ & Age: How Intelligence Changes Over Time
IQ scores aren’t static—they change as we grow.
Childhood (6-12 years): Rapid cognitive development
Teenage Years (13-19 years): Logical reasoning strengthens
Adulthood (20-50 years): Peak intellectual performance
Older Adults (50+ years): Processing speed may decline, but wisdom increases
Teenage Years (13-19 years): Logical reasoning strengthens

Older Adults (50+ years): Processing speed may decline, but wisdom increases
Your brain’s peak cognitive speed is around age 25, but problem-solving ability stays strong into your 50s!
Gender & IQ: Do Men and Women Think Differently?
Historically, some studies suggested gender-based IQ differences. However, modern research confirms that men and women have equal average IQs, but excel in different areas:
| Category | Men | Women |
|---|---|---|
| Logical Reasoning | Higher | Slightly lower |
| Verbal Skills | Slightly lower | Higher |
| Emotional Intelligence | Moderate | Higher |
| Spatial Intelligence | Higher | Slightly lower |
IQ differences are minor, and environment plays a crucial role in cognitive development.
Can IQ Be Improved?
While IQ is partly genetic, cognitive training can enhance problem-solving skills!
