THAUMAS: the active discovery and transfer test

An untimed online test of active discovery and transfer: 40 problems in four families of ten (diagnostic experiments, target construction, structural transfer and minimal repair), from the THAUMAS research edition T0.1.0. Each family opens with a guide page. Every problem hides a small system and lists eight experiments; you may run four of them before you answer. Every problem has exactly one answer, and four well-chosen experiments are always enough to determine it, as an exhaustive computer check of every problem shows.

Each problem lists its eight experiments, P1 to P8, on its page. Run up to four of them, in any order: press Run in the Experiments panel, and the server runs that experiment on the problem's hidden system and shows its result (lamps, a frame of shapes, a symbol, or accepted and rejected). A result you have seen stays with the problem, on any device, and seeing it again costs nothing. Choose with care: four results can determine every answer, but only when they are the right four. The experiments you run are part of your sealed record.

THAUMAS is untimed. From the moment you begin, your attempt stays open for 90 days: work in as many sittings as you like, on any device, with your private link. Every answer and every experiment is saved on the server as you give it. When you are done, submit: your result and certificate appear at once. An attempt still open after 90 days is submitted with the answers saved by then.

Yes: up to four attempts, each on a form you have never seen. THAUMAS has four forms built on the same blueprint with different problems, so what you learned on one form does not carry its answers to the next. A new attempt can begin 90 days after your previous one was submitted, and one attempt is open at a time. Every attempt has its own fee and its own certificate, and your best result counts for the societies. Register every attempt with the same email. Only first attempts go into the norms data.

The US$50 fee, paid through PayPal before the attempt opens, covers one attempt: the online test on a new form, its scoring, your result with its PDF certificate, and the review of one society application. Each retake has its own fee. Admission as a full member of a society carries no further fee.

THAUMAS is a research edition. Its provisional model norms TM0.1 place raw scores 1 to 39 between IQ 104 and 238 (SD 15), using a model whose item difficulties are assumed: no norming sample has been tested yet, so a score is a provisional position on the THAUMAS scale, not a percentile of the population, and no percentile is reported. The model error is about 5.4 IQ points from about IQ 131 to 209, and a perfect score is shown at the nominal cap of IQ 250. The four forms are built alike, from the same families and difficulty bands, but are not yet equated. The norms will be replaced by empirical norms as results come in.

Yes. IQ 147 or higher meets the criterion of the Nereid Society, and the fee covers the review of your application. IQ 160 meets that of the Mesopelagic Society, whose membership carries a one-time fee, and IQ 190, 205 and 220 those of the Aphotic, Hadal and Exocosm Societies. Associate membership of the Nereid Society (IQ 135 to 146) and subscription to the Aphotic Society (IQ 180 to 189) carry a one-time admission fee. Your best attempt counts.

The answer keys never leave the server, and your result never shows which problems you solved. Each form's pages are shown only to its own sessions, and a retake is always on a form you have never seen. The experiments run on the server, so the hidden systems never reach your browser. Each page is drawn on the screen with a faint watermark of your name and certificate ID. While a problem is on screen, the test page records leaving the test window, screenshot shortcuts (Print Screen, Windows+Shift+S, Command+Shift+3, 4 or 5), printing (Ctrl+P or Command+P), copy, right-click and drag attempts, attempts to paste into the answer fields (pasting is switched off), and AI assistant add-ons that insert themselves into the page; the server keeps its own times and notes right answers given moments after a long absence, and right answers that the experiments you ran could not have determined. The record is sealed when you submit, and its fingerprint is printed on your certificate. None of this changes a score: the author reviews it before any society admission. The author's integrity report of each attempt lists all of it, problem by problem. An untimed test cannot rule out every form of help, which is why you declare that you will work alone, and why the author reviews every result before it counts for a society.

Your private link (shown when your test is ready, and kept in this browser) reopens your test on any device. If you lose it, use “Recover my test” with the PayPal Transaction ID from your receipt and the email you registered with. Answers that are complete are saved on the server; a part you have only begun is kept in the browser you were using until you complete it.
