Mental Age Test

This test is originally from Japan, where it's named 精神年齢チェック. Please answer every question honestly. Nobody will see your answers.

The result has nothing to do with your Intelligence Quotient. For the purpose of this test, we define Mental Age as a measure of a person's psychological abilities in comparison to the number of years it takes for an average child to reach the same level. For example, if your mental age is 10, regardless of your actual chronological age, you are mentally similar to a 10-year-old.

Can you give more background to this mental age test?

Good question. Our mental age test was first released in Nov 2013 on my personal website. The original content was introduced to me by a friend who's from Japan. However, I couldn't find any online resource for it. It has now been translated into 32 languages and is one of the most shared webpages on Facebook and Twitter. Many famous people have taken this test. According to Google Analytics reports, more than 57,400,000 people from more than 239 countries/regions have taken this test. (as of Jul 18, 2022)

In Feb 2014, I moved this webpage from my personal website to “arealme.com”, and the Mental Age Test became the first test to exist on arealme.com.

Other fun facts about our mental age test

  • In 2013, you couldn't begin the test without first entering your actual age. The average age of those taking this test was 23.
  • In 2014, due to privacy protection, we allowed the test taker to opt out from entering his/her actual age. The average age to take this test was then 16. It seems people who are under 18 do not care about letting others know their real age.
  • Question #3 is: "I spend most of my time on ___________.". We added a textfield to let users input their own answer. The most answered items are:
