Dark pattern
also called deceptive design (deceptive-design), deceptive pattern (deceptive-design), manipulative design (community)
An interface arranged to make the reader do something they did not intend and would not have chosen, by exploiting how attention and defaults work.
A dark pattern is not a mistake. Every ingredient of it is something an honest interface also uses: emphasis, defaults, wording, placement, timing. What makes it dark is the direction those tools are pointed. The glowing button is the one that earns revenue, the greyed link is the one that does not, and the wording of the refusal is written to make refusing feel like an admission. Nothing on the screen lies. The screen is simply arranged so that the fastest, calmest path through it is the one the reader would not have picked if the two options had been drawn as equals.
Harry Brignull coined the phrase in 2010 and catalogued it at darkpatterns.org, which now runs as deceptive.design under a name that survives translation and does not lean on “dark” as a synonym for bad. The catalogue is the useful part: the umbrella word gets you into the argument, and the specific word wins it. Confirmshaming makes declining an insult (“no thanks, I like paying full price”). A roach motel is easy to enter and deliberately hard to leave, which is what a one-click subscription with a phone-only cancellation is. Drip pricing hides fees until the last screen. Preselection ticks the box for you. Misdirection puts the decoy where the eye lands first. Naming the specific one is what turns a design review comment from taste into a finding.
The vocabulary now has legal weight, which is why it is worth using precisely. The US Federal Trade Commission published a staff report on dark patterns in 2022 and has brought enforcement actions over subscriptions that were hard to cancel. In the EU, the Digital Services Act bans interfaces that distort or impair a user’s ability to make free choices, and consent under the GDPR has to be as easy to refuse as to give, which is what makes a cookie banner with a prominent Accept and a buried Reject a compliance question rather than an aesthetic one. Accessibility rules bite too: a decline link that fails contrast fails WCAG whatever its intent was.
The honest test is not whether the interface is persuasive. Persuasion is allowed and is most of what design does. The test is whether the design works against the person’s own interest and would stop working if it were explained to them out loud. An interface that gets more sign-ups when the cancel path is hidden is not a better interface. It is the same interface with a hostage.

Variants
- Comparison prevention
Structuring plans or products so their features and prices cannot be lined up, forcing a decision that no side-by-side reading would support.
- Confirmshaming
Wording the decline option so that choosing it is an admission of something embarrassing, making refusal feel like a confession rather than a choice.
- Disguised ad
An advertisement styled to look like a control or an item of content, so the click it collects was aimed at something else entirely.
- Drip pricing
Advertising a low headline price and adding mandatory fees one screen at a time, so the true total only appears once the buyer is committed.
- Fake scarcity
Claiming limited supply that is not real, with stock counts or demand messages generated to pressure a decision rather than report a fact.
- Fake social proof
Manufacturing evidence that other people approve, through invented reviews, testimonials, or live activity messages nobody actually generated.
- Fake urgency
Presenting a deadline that does not exist, usually a timer that resets on reload, so the reader hurries a decision they had time to make.
- Forced continuity
Turning a free trial into a paid subscription automatically, with the card taken up front and no reminder before the first real charge.
- Friend spam
Asking for access to a contact list under one pretext and using it to send invitations that appear to come from the reader.
- Misdirection
Using contrast, size, and position to pull attention to the option the business prefers while the other option is present but visually demoted.
- Nagging
Interrupting a task again and again with the same request, so that agreeing becomes the cheapest way to be left alone.
- Obstruction
Putting deliberate hurdles in front of an action the business does not want taken, so the effort itself does the discouraging.
- Preselected opt-in
Arriving at a choice with the answer that benefits the business already ticked, so consent is collected from everyone who does not notice.
- Privacy zuckering
Steering people into sharing more about themselves than they meant to, by making the permissive choice the easy one and the private choice several clicks deep.
- Roach motel
Making entry into a commitment take one click and exit take a phone call, a chat queue, or a buried page, so the asymmetry keeps people subscribed.
- Sneak into basket
Adding an item the buyer never chose, an insurance, a donation, a warranty, into the cart through a preselected control found earlier in the flow.
- Trick wording
Phrasing a choice so its plain reading is the opposite of its effect, typically through double negatives or a label that describes the wrong outcome.
