Disclaimer

Everything on this site is for entertainment and self-reflection. The test is an informal questionnaire, not a psychological assessment. It has no validated scoring, no clinical use and no predictive value. A result does not describe your intelligence, your maturity, or your future.

Nothing here is medical, psychological or legal advice. If you are worried about your health, your wellbeing or your safety, speak to a qualified professional. Our help resources page lists places to start.

"Mental age" is used here in its casual, quiz-genre sense only. It is not the historical psychometric term, and this site makes no scientific claim about age, cognition, or development. If you're looking for a clinical or research definition of the term, this isn't that. See our about page for what this site actually is, and our history page for where the phrase comes from.

Your result is the average of the age values attached to the answers you picked. It is not compared against other people or against any outside study or dataset, and it is meant only as a rough, informal reference point. You can see exactly how it is worked out on the age guide, and your result page lists every answer you gave.

If we later publish comparisons between your result and other readers, they will come only from people who took this specific test, they will be shown with the sample size behind them, and they will not be a statement about the general population. See the averages page for where this stands.

We try to be accurate and we publish sample sizes alongside any figure we report. Where we do not have data we say so. If you find an error, tell us via the contact page and we will correct it and note the correction.
