Why Do We Collect Age, Gender & Education?

In psychometrics and cognitive science, standardized IQ scores are not absolute point counts—they are norm-referenced comparisons against the general population (μ=100, σ=15).

Processing speed, visual abstraction, and working memory performance change naturally across different stages of life. A raw score achieved by an 18-year-old reflects different normative percentiles than the same score achieved by a 55-year-old.

📊 Age Cohort Norming
Your age places your score on the exact empirical distribution curve for your peer age group.
🧠 Demographic Balancing
Gender and educational background help normalize variance in domain-specific tasks (e.g. arithmetic vs spatial folding).
🔒 100% Private & Anonymous
Demographics are used solely for calculating psychometric statistics and are never shared or sold.
