Question 1

How are the questions generated?

Accepted Answer

The AI is prompted with a detailed set of instructions based on established psychometric principles. It's directed to create questions across multiple domains (logical, verbal, spatial reasoning) at a specific difficulty level. We employ a schema enforcement feature via the Gemini API to ensure the AI's output is always in a structured, usable JSON format, containing the question, four options, and the correct answer.

Question 2

Is the test scientifically valid?

Accepted Answer

While this test is not a substitute for a clinical diagnosis by a psychologist, it is built upon scientific principles of psychometrics. The questions are designed to measure fluid and crystallized intelligence, similar to traditional IQ tests. The AI's evaluation process simulates the scoring and analysis that a human expert would perform.

Question 3

How is the IQ score calculated?

Accepted Answer

The AI analyzes the pattern of correct and incorrect answers. It doesn't just count the number of correct responses; it considers the difficulty of the questions and the cognitive domains tested. Based on this analysis, it calculates an estimated score on a standardized scale with a mean of 100 and a standard deviation of 15, which is the standard for most IQ tests.

Question 4

Is my data private?

Accepted Answer

Yes. We are committed to your privacy. The test questions and your answers are sent to the AI for processing but are not stored or linked to any personal information. If you sign in, your test results are linked to your user ID to provide a test history, and an anonymous name is generated for the leaderboard. Your real name is never shown.

Question 5

How does the leaderboard work?

Accepted Answer

To qualify for the leaderboard, you must complete at least one test at each difficulty level (Easy, Medium, and Hard). Your final leaderboard score is a weighted average of your highest score in each category: 20% from your Easy best, 30% from Medium, and 50% from Hard. Your rank is updated automatically whenever you set a new personal best in any difficulty.
