Self-assessment
A free, private questionnaire that measures how well documented your interests are — not what kind of person you are. Around four minutes, no account, no email, and nothing leaves your device.
Every interest in the catalog carries a popularity index from 0 to 100 — a weighted geometric mean of five cited signals: estimated prevalence, search interest, community size, cultural visibility and research attention. The assessment reads your selections against that scale and returns their weighted average position, expressed as a percentile of the 323 interests it can ask about.
That number says how well documented your interests are — how much research, survey data and clinical literature exists behind them. It is a statement about the literature, not about you. A low percentile means the things you picked have been studied less, which is true of a great many of the 462 interests in the catalog.
The run opens with 11 questions, one for each category family the catalog is divided into. Keep a family and it asks about specific interests inside it; turn one down and it never comes back. That caps the run at 35 questions and means nobody is asked about areas they have already declined.
The interests it asks about are picked deterministically and spread across each family’s documentation range, rather than skimming the best-known ones — if it only asked about famous interests, everyone would land on the same percentile. Rank and prevalence are withheld until the result: telling you something is the 24th most common interest on earth before you answer would change the answer.
Below 3 selections no percentile is shown at all. An average over one or two answers is noise, and publishing it would be worse than publishing nothing.
Nothing is sent anywhere. There is no account, no email and no analytics on your responses — the answers are written to this browser’s local storage so a refresh resumes the run, and a single button deletes them. A shared result encodes counts only: the percentile, how many interests were selected, and how they spread across families and prevalence bands. It holds no entry names or ids, so it cannot be decoded back into your selections. This is a reference tool and not a diagnostic instrument; it produces no clinical finding about anyone.
It measures how well documented your interests are, not what kind of person you are. Every interest you select carries a place on the catalog's 0–100 popularity index, and the result is the weighted average of those places across 323 interests the test can ask about.
Each selection contributes its percentile on the popularity index — a weighted geometric mean of five cited signals: estimated prevalence, search interest, community size, cultural visibility and research attention. Answering “curious” counts half as much as “yes”. Below three selections no score is shown at all.
Between 11 and 35 questions, or roughly four minutes. It opens with one question per category family and then asks about specific interests only inside the families you keep, so you are never asked about areas you have already turned down.
Yes. There is no account, no email and no sign-in. Your answers are written to your own browser's local storage and are never transmitted, measured or logged. A single button deletes them.
Yes — that is the default. The share link encodes counts only: your percentile, how many interests you selected and how they spread across families and prevalence bands. It contains no entry names or ids, so it cannot be decoded back into your selections.
Those return a role or a label from an instrument nobody published. This returns a position on a measure that is published in full, cited per entry, and used identically everywhere else on the site. It is a reference tool, not a diagnostic instrument, and it makes no clinical claim about anyone.
No. A low percentile means the interests you selected have less research and survey data behind them — a statement about the literature, not about the person. Many of the 462 interests in the catalog have never been surveyed at scale.
