Dark Patterns (Privacy)
Deceptive user-interface designs that trick people into sharing more data, accepting wider terms, or agreeing to tracking they did not intend to consent to.
Also known as: deceptive design, manipulative UX, consent manipulation

Dark patterns in privacy contexts are user-interface choices that make it easy to accept privacy-invasive options and difficult or confusing to choose privacy-protective ones. Common examples include pre-ticked consent boxes, accept buttons styled in bright colours with decline options hidden in small grey text, confusing double negatives ('untick to not receive marketing'), and mandatory account creation for activities that could be completed without one.
The manipulation affects real outcomes: studies have consistently shown that consent rates for data collection are dramatically higher when dark patterns are used compared to genuinely neutral interfaces. Data collected through manipulated consent then enters the data-broker ecosystem and can be used for targeted fraud and scam profiling.
Regulatory frameworks including the EU's GDPR, UK GDPR, and FTC enforcement actions have targeted specific dark patterns as non-compliant consent mechanisms. Consumers can counteract them by looking for equivalent options in account settings, using browser extensions that surface hidden options, and reporting manipulative interfaces to data protection authorities.
