背景にある科学
There is no scientific mental age; this is a fun read, and it says so. What it actually measures is three things personality research does track and that shift, on average, with age: prudence (planning, saving, the early night), appetite for novelty, and attachment to the familiar. Younger adults score, on average, lower on the first and third and higher on the second; the pairs here are written for MoodyWonder and place you against that average. Treat the number as a caption, not a finding. 測定方法をくわしく読む →

よくある質問
Is mental age a real thing?
No — and this page does not pretend otherwise. What is real is that prudence, appetite for the new, and attachment to the familiar shift with age on average, and this places your answers against that average. The number is a caption, not a diagnosis of anything.
I got an old soul and I'm twenty-four. Is that bad?
It means you plan, you keep what matters, and a quiet night is a good night — habits that most people grow into and you already have. The share card says so. The only cost is a small one: make sure the appetite for new things does not get scheduled out entirely.
Will this change if I retake it?
A bit, with your mood and your month. Prudence rises after a bad surprise; novelty rises on holiday. Retake it when you are somewhere different and see which dial moved.
