Dark Patterns
If the design only works while the user misunderstands it, it's not persuasion — it's a trap with a UI.

Forms & parts of speech
Definition in plain terms
Dark patterns are interface designs that TRICK users into actions they didn't intend: subscriptions that take one click to start and a phone call to end (the roach motel), pre-checked add-ons sneaking into baskets, countdown timers counting nothing, guilt-button copy ('No thanks, I hate saving money' — confirmshaming), drip pricing that reveals fees at the last step. UX researcher Harry Brignull coined the term in 2010 and built the taxonomy ( now also called 'deceptive patterns') naming each trick.
The mechanics
The defining test: the design profits from MISUNDERSTANDING — remove the confusion and the behavior stops. That's the line from persuasion (which survives transparency) and nudging (which requires easy exits). The catalogue's families: obstruction (hard exits), sneaking (hidden costs, basket stuffing), interface interference (visual tricks, disguised ads, trick questions), forced action, and social-proof fakery (fabricated activity counters). The era's turn is legal: the FTC's click-to-cancel rulemaking and negative-option enforcement, the EU's DSA and GDPR consent standards — dark patterns moved from UX-twitter shame to regulatory exposure with fines attached, and 'we A/B tested it' is not a defense.
When it matters
Marketers need the taxonomy as a compliance audit and a brand-risk map: short-term conversion from tricks converts into churn, chargebacks, support load, review damage, and now legal exposure — the lifetime math almost never clears. The audit method: walk every flow as a hostile journalist would (signup to cancel, price to final charge), name any pattern found with Brignull's vocabulary, and fix in order of harm. The competitive read: in categories soaked with traps, honest architecture is differentiation — 'easy to cancel' is now a selling point because the bar fell that far.

Origin & history
Coined by London UX researcher Harry Brignull in 2010, who registered darkpatterns.org to name and shame the tricks ('a pattern library with the sole purpose of naming the worst practices'); he later renamed the field 'deceptive patterns' — and regulators on both Atlantic shores adopted the catalogue nearly verbatim.
