Halo effect
"Rihanna's vision of haircare, makeup, skincare + fragrance for all."

The psychology

Why it nudges

Fenty Beauty uses Rihanna as the signal for what to buy: the title is "Fenty Beauty by Rihanna", and the brands row reads "Rihanna's vision of haircare, makeup, skincare + fragrance for all" beside four photos of her. Her fame colours judgement of the products, which is the halo effect (Nisbett & Wilson 1977). Rihanna is the founder, so some of this is real product authority rather than pure halo. Whether it lifts sales is not public.

Steal this, honestly

If your founder is the draw, tie them to choices they really made, and say which.

What to test: Founder-led brands row vs product-led row. Measure add-to-bag.

Next: run it on your product

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.
