IQ (Intelligence Quotient) is a standardized score measuring cognitive abilities relative to the general population. Average IQ is 100, with most people scoring between 85-115.

Can online IQ tests be accurate?

Online IQ tests provide rough estimates for fun and self-discovery. Professional IQ tests administered by psychologists are more accurate and comprehensive.

Comprehensive Guide to Intelligence Quotient (IQ)

Your Intelligence Quotient (IQ) is a measure of your cognitive ability compared to the general population. While often misunderstood as a fixed number, it represents a snapshot of your potential for reasoning, problem-solving, and understanding complex ideas.

Fluid Intelligence (Gf)

Fluid intelligence is the ability to solve novel problems, identify patterns, and use logic in new situations. It is independent of acquired knowledge. This calculator primarily tests Gf through number series and matrix patterns. Fluid intelligence typically peaks in early adulthood.

Crystallized Intelligence (Gc)

Crystallized intelligence is the ability to use learned knowledge and experience. It includes vocabulary, general knowledge, and verbal analogies. Unlike Gf, Gc tends to increase with age as you learn more and gain experience.

The Bell Curve: Where Do You Stand?

IQ scores follow a Normal Distribution (Bell Curve) with a mean of 100 and a standard deviation of 15. This means:

130+ (Top 2%) Very Superior / Gifted
Often eligible for high-IQ societies like Mensa.
115 - 129 (14%) High Average / Superior
Found in many professionals, engineers, and academics.
85 - 114 (68%) Average
The vast majority of the global population falls in this range.

Can You Increase Your IQ?

Brain Structure

While genetics play a major role (approx. 50-80%), neuroplasticity means your brain can physically change. Learning new skills thickens the cortex.

Dual N-Back

Studies show that consistent practice with working memory tasks (like the Dual N-Back game) can temporarily boost fluid intelligence scores.

Health Factors

Aerobic exercise, proper sleep, and a diet rich in Omega-3 attributes significantly to optimal cognitive function and maintenance.

History of IQ Testing

The concept began in 1904 with Alfred Binet and Theodore Simon, who developed a test to identify French school children appearing to face learning difficulties. Later, Kevin McGrew and others evolved these into the modern Woodcock-Johnson and Wechsler Adult Intelligence Scale (WAIS), examining comprehensive cognitive abilities beyond just "school smarts."

Important Disclaimer: This assessment is for educational and entertainment purposes only. It is a simplified screening tool designed to estimate G-Factor based on logic and pattern recognition. It is NOT a substitute for a professionally administered clinical IQ test (such as the WAIS-IV or Stanford-Binet 5). Standardized tests require proctored environments to be valid. Do not use these results for diagnostic or employment purposes.
