What to steal

If you sell an evaluation to people who already suspect a diagnosis, show a result that was not a diagnosis too.
Put the caveat on the card, as the Snapshot does: “It’s a snapshot, not a diagnosis.”

What to test next: The ‘looking for a sign’ quote vs a quote from someone who was not diagnosed. Measure evaluation starts.

In plain words

Why it works

ADHD Online uses confirmation bias (Nickerson 1998) on a paid evaluation. Under “Save time and money”, the comparison shows ADHD Online at $219 against “Traditional In-person” at $1,689, and ADHD Online is ahead on every row in the capture: cost, wait to take the assessment, wait for diagnosis, and total time. The footnote says costs exclude treatment and medication, and that the $1,689 figure is a nationwide average from a December 2024 survey published by ADDitude, not a clinic’s price printed on this page. Under “What our patients are saying...”, Heather B’s five-star quote reads “Amazing customer service and wonderful Doctors! I highly recommend! Life changing! If you are looking for a sign, this is it!” Above this capture, on the same page, the clinical card says “Choose this if something feels off and you want a clinical answer”, the Snapshot card says it “is a snapshot, not a diagnosis”, and the clinical card says “Not every evaluation results in a diagnosis.” Whether the table or the quote lifts evaluations is not public.

Honest nudge or dark pattern?

Grey area

Grey area: a quote that tells the reader they were looking for a sign sits on a paid diagnostic evaluation. The page does say a diagnosis is not guaranteed and that treatment is separate.

Rules: say a brand "uses" a tactic, never that it "worked"; outcomes are not public unless the company published them; no invented uplift estimates; flag mixed evidence. Honest nudge = true, visible, easy to reverse, and in the user's interest. Dark pattern = hides costs, fakes scarcity or popularity, shames, or makes leaving harder than joining. Quote company-published results as "X reports", with the source link, and don’t generalise them. Don’t cite retracted or failed-to-replicate studies as support (e.g. Ariely & Wertenbroch 2002). Don’t state study figures unless they’re on this page or in a source you can link. If an idea crosses the line, link the matching deceptive.design pattern.

Tasks:
1. Ask me for my product, the flow (URL or screenshots) and the goal.
2. Audit where this pattern already appears, or could, in that flow.
3. Propose 2-3 ethical experiments: hypothesis, variant copy or UI, primary metric, and a guardrail metric (refunds, complaints, cancellations).
4. Flag every dark-pattern risk and say how to stay on the honest side.
