The unsubscribe button is grey and tiny. The stay-subscribed button is large and green. Someone made that choice.
Literal meaning: Dark patterns are interface design choices that work against users’ interests — manipulating, misleading, or coercing users into actions they would not take if the interface were honest. The term was coined by UX designer Harry Brignull in 2010, who began documenting specific patterns on darkpatterns.org. The site is now at deceptive.design.
Origin: Brignull introduced the concept after noticing systematic design choices across commercial websites that exploited users’ cognitive tendencies and assumptions. He catalogued them by type: roach motel, sneak into basket, hidden costs, confirmshaming, trick questions, and others. The concept gained rapid traction in UX practice, academia, and — from 2021 onward — in law. In 2024, Colin Gray, Nataliia Bielova, Cristiana Santos, and Thomas Mildner published a comprehensive three-level ontology at ACM CHI, harmonising 10 regulatory and academic taxonomies into 65 standardised dark pattern types. The same year, Gray and colleagues documented $245 million in FTC sanctions against Epic Games for dark patterns in Fortnite.
Interface design choices that work against the user — making it easy to do what the platform wants and hard to do what you want.
The Appeal: From a design and business perspective, dark patterns work. They increase conversion rates, reduce cancellations, and maximise data disclosure. The financial incentive is clear and measurable. Some patterns are so normalised — pre-ticked boxes, difficult unsubscribe flows — that they are no longer experienced as manipulation by users or designers.
The Friction: Gray et al.’s (2024) ontology identifies five high-level strategies: sneaking, obstruction, interface interference, forced action, and social engineering. Each has meso-level and low-level variants — 65 types in total. Deceptive Design is the academically and legally preferred term: it moves the frame from aesthetics to accountability. In 2022, dark patterns were codified into EU law in the Digital Services Act, the Digital Markets Act, and the California CPRA. The EDPB issued specific guidelines for dark patterns in social media interfaces. Courts have begun issuing sanctions. Predatory Design is the child-specific intensification. Nudging occupies the legally ambiguous zone between dark patterns and legitimate persuasion. Fair Patterns — developed by Marie Potel-Saville and others — is the direct design counterpart.
Why This Matters: Dark patterns name the gap between what an interface appears to offer and what it is designed to do. Once you know the vocabulary — roach motel, confirmshaming, false hierarchy — every interface becomes readable as a set of choices made by someone, for someone’s benefit. Usually not yours.
