Dark pattern

An interface designed so the outcome the operator prefers is easier than the one the person would choose, and, in consent interfaces, a defect in the consent itself.

Effect
Consent may not be freely given
Most cited
Reject harder than accept
Guidance
EDPB deceptive design patterns

The ones that come up

  • Accept in one click; reject behind a settings screen and a save
  • A prominent coloured accept button next to grey text for refusal
  • Pre-ticked optional categories, which Planet49 settled directly
  • Language that frames refusal as damaging the experience
  • A banner that reappears every page load until the visitor gives in
  • No visible way to change a decision after it has been made

The European Data Protection Board has published guidance on deceptive design patterns in social media interfaces that reads across directly, and several supervisory authorities have made the reject-parity point in enforcement rather than in guidance.

A test you can apply in a minute

Count the clicks

Comparable prominence and effort are strong design and regulatory baselines, not identical statutory wording everywhere. If refusal takes materially more effort or is visually suppressed, investigate whether the interface steers the choice. StrongPrivacy’s default puts "Accept all" and "Reject optional" at the same level to reduce that risk.

Common questions

Does a dark pattern make consent invalid?

It can. Consent must be freely given and unambiguous; an interface engineered to make refusal costly undermines the first, and one that makes acceptance the accidental outcome undermines the second.

Is a banner that reappears on every page a dark pattern?

If it reappears because refusal was not persisted, it is nagging towards acceptance. A refusal should be remembered exactly as an acceptance is.
