Our platform processes cognitive assessment data from participants in 142 countries, maintaining one of the largest active databases of standardized intelligence metrics in the digital space.
Real-Time Database Metrics
Data updated in real-time. Statistics reflect assessments completed in the last 90 days.
The Bell Curve: IQ Distribution
IQ scores follow a Gaussian (Normal) Distribution with a mean of 100 and standard deviation of 15. This means:
- 68% of the population scores between 85-115 (±1 SD)
- 95% of the population scores between 70-130 (±2 SD)
- 99,7% of the population scores between 55-145 (±3 SD)
| IQ Range | Classification | % of Population | Percentile |
|---|---|---|---|
| 145+ | Exceptionally Gifted | 0,13% | 99,87º |
| 130-144 | Highly Gifted | 2,14% | 97,7º-99,9º |
| 120-129 | Superior | 6,87% | 90,9º-97,7º |
| 110-119 | Above Average | 16,12% | 75º-91º |
| 90-109 | Average (Norm) | 49,86% | 25º-75º |
| 80-89 | Below Average | 16,12% | 9º-25º |
| 70-79 | Borderline | 6,87% | 2,3º-9º |
Average IQ by Age Group
Our database reveals subtle variations in average performance across age groups, consistent with fluid vs. crystallized intelligence theory:
Technical Note: These are population averages. Individual variation far exceeds age-related trends. Many individuals over 55 score well above younger cohorts.
Data Collection and Privacy
All statistics are derived from anonymized, aggregated assessment results. We do not collect personally identifiable information beyond email addresses (used exclusively for results delivery).
Our database is continuously refined to maintain representativeness across:
- Geographic distribution (weighted by population density)
- Educational background (to control for test-taking experience)
- Linguistic proficiency (culturally fair items minimize bias)
