What Does IQ Measure?
IQ (Intelligence Quotient) measures cognitive abilities including logical reasoning, problem-solving, pattern recognition, spatial visualization, and verbal comprehension. It does not measure creativity, emotional intelligence, or wisdom.
IQ Score Ranges
- 130+ — Very Superior (top 2%)
- 120–129 — Superior
- 110–119 — High Average
- 90–109 — Average (most people)
- 80–89 — Low Average
- 70–79 — Borderline
- Below 70 — Intellectual disability range
Average IQ is 100. About 68% of people score between 85 and 115.
Is IQ Fixed or Can It Change?
Research shows IQ is partially malleable, especially during childhood and young adulthood. Brain training, education, sleep, nutrition, and reducing stress all measurably affect cognitive performance.
Science-Backed Ways to Improve Cognitive Performance
- 🧩 Daily brain puzzles — logic, pattern, spatial. Try IQ Galaxy.
- 😴 Sleep 7–9 hours — memory consolidation happens during REM sleep.
- 🏃 Exercise — increases BDNF (Brain-Derived Neurotrophic Factor), grows new neurons.
- 📚 Read daily — builds vocabulary and processing speed.
- 🧘 Meditate — reduces cortisol, improves working memory and focus.
- 🥦 Nutrition — omega-3, blueberries, and reducing sugar all show cognitive benefits.
IQ vs EQ: Which Matters More?
Research by Daniel Goleman suggests EQ (Emotional Intelligence) predicts career success better than IQ in most fields. The ideal is high both — IQ opens doors, EQ keeps them open.
