What is Deceptive design?
Deceptive design is the broader term for interface practices that mislead users into unintended actions, encompassing what were originally called dark patterns. The rename reflects growing consensus that the term should describe the practice (deception) rather than using a metaphor.
How it works
Deceptive design includes misdirection (drawing attention away from important information), obstruction (making cancellation or opting out unreasonably difficult), sneaking (adding items to a cart or changing terms without clear notice), and social engineering (fabricating urgency or social proof). Regulatory frameworks like the FTC’s enforcement actions and the EU’s Digital Services Act increasingly define and prohibit specific deceptive design techniques.
Applied example
A subscription service that requires a phone call to cancel (while sign-up takes two clicks) uses obstruction. The asymmetric friction is not an accident: it is designed to prevent cancellation by exploiting the effort barrier.
Why it matters
Deceptive design represents the ethical boundary of behavioral design: the same psychological principles that help people can be weaponized against them, making ethical guidelines and regulatory literacy essential for practitioners.
