Before we start

This is a short research session (about 15 minutes) testing whether a piece of writing's structure — not its content — carries information about how someone is doing. You'll answer three standard, validated questionnaires and write a short passage about your week.

Your answers are stored anonymously, linked only to a random ID generated in your browser — never your name or email. The written passage is analyzed for structural metrics only; the text itself is not stored. You can stop at any point with no penalty. Full details are in the study protocol.

You must be 18 or older and comfortable writing in English to participate.
