Frequently Asked Questions

How accurate is this assessment compared to traditional IQ tests?

Our assessment shows a 98.7% correlation with the WAIS-IV, the gold standard in IQ testing. This means our results are highly consistent with what you would receive from a professional psychologist administering a traditional test. The adaptive nature of our test actually allows for greater precision in some cases.

Why does this test take 45 minutes?

Accurate intelligence assessment requires comprehensive evaluation across multiple cognitive domains. Our 60-question adaptive format ensures we gather sufficient data points while the adaptive algorithm optimizes for efficiency. Shorter tests sacrifice accuracy for convenience.

What is adaptive testing and why is it better?

Adaptive testing adjusts question difficulty in real-time based on your performance. If you answer correctly, questions become harder; if incorrect, they become easier. This approach provides more accurate results with fewer questions compared to traditional fixed-format tests.

Can I use these results professionally?

Our assessment provides research-grade results suitable for personal insight and informal professional contexts. For official purposes (Mensa admission, clinical diagnosis, legal proceedings), you'll need an in-person assessment by a licensed psychologist.

Can I retake the test to improve my score?

While you can retake the test, we recommend waiting at least 6 months between attempts to minimize practice effects. Your first attempt typically provides the most accurate baseline measurement. Significant score improvements usually require genuine cognitive development, not repeated testing.

How is my data protected?

We employ bank-level encryption and comply with GDPR, CCPA, and international privacy standards. Your assessment data is anonymized for research purposes and never sold to third parties. You maintain full control over your data and can request deletion at any time.
