Dylan Thomas' presentation from World Usability Day on 14th November 2013.
Dark patterns are anti-patterns with a nefarious purpose - intentionally flawed designs. Carefully-crafted ‘bad’ designs; built with a pinch of psychology and a healthy dose of trickery. This is an introduction to this interesting, and often fun, side of web design and some of the methods used by companies to swindle and snare their users. This is not user-centred design!
Clipping is a handy way to collect important slides you want to go back to later.
