Dark Pattern

In graphic and web design, a dark pattern is "a user interface that has been carefully crafted to trick users into doing things, such as buying insurance with their purchase or signing up for recurring bills."[1][2][3] The neologism dark pattern was coined by Harry Brignull in August 2010 with the registration of darkpatterns.org, a "pattern library with the specific goal of naming and shaming deceptive user interfaces."[4][5]



Bait-and-switch patterns advertise a free (or greatly reduced) product or service which is wholly unavailable or stocked in small quantities. After it is apparent the product is no longer available, they are exposed to other priced products similar to the one advertised.[6][7]

Forced disclosure

A forced disclosure pattern offer low-cost or free services, but require that the user divulge sensitive information such as credit card information, personal addresses, and phone numbers. Some companies will then sell this information to advertisers.[6][7]

Roach motel

A roach motel or a trammel net[8] is a situation that is easy or straightforward to get into, but difficult to get out of. Examples include businesses that require subscribers to print and mail their opt-out or cancellation request.[6][7]
