Dark patterns are those in which the designer uses his knowledge of the user and his behaviors to achieve purely commercial objectives, without taking into account ease of use or user satisfaction.
The definition of dark pattern was established by Henry Brignull in 2010, who defined them as “tricks used in websites and apps that make you do things that you didn’t mean to, like buying or signing up for something”.
Also Narayan et al. refer to dark paterns as deceptive patterns, and Westin & Chiasson as manilupativos.
