Harry Brignull names dark patterns

Designer Harry Brignull launched darkpatterns.org in 2010 to name deceptive interface designs. The term's history is documented; the psychology attached to it is researchers' interpretation, and a 2018 taxonomy grouped 118 practitioner examples into five strategies.

What happened

UX designer Harry Brignull launched darkpatterns.org in 2010 as a pattern library for deceptive interface designs, and his own site says he coined the term dark patterns. A List Apart published his article on 1 November 2011 (issue 338) and says the site was created in August 2010. The site is now called deceptive.design.

The psychological idea

Dark patterns are interface designs that deceive users. Brignull's 2011 article names hidden costs, trick questions, forced continuity and burying negative feedback as examples. A 2018 taxonomy by Gray and colleagues analyzed 118 practitioner-identified examples and grouped them into five strategies: nagging, obstruction, sneaking, interface interference and forced action.

In practice

The pattern library named and shamed examples of deceptive interfaces. Brignull's article reports that Hotels.com revealed taxes and fees only at the final checkout step until a redesign showed full prices, and that Audible enrolled single-audiobook buyers in monthly memberships and later revised its wording. These are Brignull's reports of company behavior and were not checked against company records.

Why it mattered

The term gave designers, researchers and later regulators a shared word for deceptive interface design. Later records on this site, including the crawl of shopping sites by Mathur and colleagues, use the same vocabulary.

Limits and qualifications

The term describes design practice, not a tested psychological mechanism. The sources opened do not show which cognitive bias any pattern uses, so mapping patterns to psychology is interpretation. The coining date rests on Brignull's own account, and the A List Apart article does not say who coined the term. Only a web summary of the 2018 taxonomy was read, not the paper itself.

Evidence behind the claims

Brignull's site says he founded darkpatterns.org in 2010, coined the term dark patterns, and that the site is now deceptive.design.
