What this test separates
Wanting to be alone comes in two flavours. One is temperament: you don't dislike people, you're simply built so that solitude puts energy back in. The other is a state: you were fine before, and at some point people started costing more than you had. From the outside they look identical — you cancel plans, you leave the group chat unopened — which is exactly why it's hard to tell from the inside too.
The distinction matters because the fixes point in opposite directions. If it's temperament, protecting your alone time is the whole answer and there is nothing to feel guilty about. If it's depletion, more alone time doesn't help; lying down for a week and still waking up tired is what that looks like. What you need then isn't more isolation, it's a different kind of recovery. Same behaviour, opposite prescription.
So this test never asks whether you consider yourself introverted. It asks how you felt the morning after a weekend spent alone. It asks what actually went through your head the last time you turned down an invitation. It asks how much you see people now compared to three years ago. Whether solitude restores you or just passes is the line everything falls on. Six tiers, from fully charged to shut down. Land near the top and it's temperament, so relax. Land near the bottom and something else may be hiding behind the word introvert. This is a reference test, not a diagnosis.
