Dark Pattern
An interface designed to get a person to do something they did not intend — now regulated in the EU, the US and elsewhere.
Design DisciplinesDark patterns exploit how people actually read interfaces: pre-ticked consent, a cancel flow buried behind six screens, a decline button styled as secondary text beside a prominent accept, costs disclosed only at the final step, countdown timers that reset on reload. Each one works in the short term, which is why they persist and why they show up in A/B tests as wins.
The category is no longer merely unethical. The EU Digital Services Act prohibits interfaces that distort or impair a user's ability to make free decisions; GDPR requires consent to be freely given and as easy to withdraw as to grant; the US FTC has brought enforcement actions over negative-option billing and obstructed cancellation, with a rule requiring cancellation to be as simple as signup. “Deceptive design” is the term regulators use.
They also cost money directly
An obstructed cancellation produces a chargeback, a one-star review and support load instead of a clean churn event. The metric that improved was the one being measured; the ones that got worse were not on the same dashboard.
In practice
A subscription business routed cancellation through five retention screens. Cancellations fell 22% and chargebacks rose 3× — customers went to their bank instead. Net of chargeback fees, dispute handling and the review damage, the retention flow lost money in its first full quarter.
Where teams get it wrong
- Pre-ticked consent, which is not consent under GDPR.
- Cancellation harder than signup, now specifically regulated in several jurisdictions.
- Decline options styled to be less visible than accept.
- Costs revealed only at the final step of a checkout.
- Judging a pattern by the metric it was built to move, ignoring chargebacks, reviews and support load.

Frequently Asked Questions
What are dark patterns?
Interface choices designed to get people to do something they did not intend — pre-ticked boxes, obstructed cancellation, visually demoted decline options, costs hidden until the last step.
Are dark patterns illegal?
Several are. The EU Digital Services Act prohibits interfaces that impair free decision-making, GDPR invalidates consent that is not freely given, and the US FTC has enforced against obstructed cancellation and negative-option billing.
