Clicks and tricks: The dark art of online persuasion.

Internet users are inundated with attempts to persuade, including digital nudges like defaults, friction, and reinforcement. When these nudges fail to be transparent, optional, and beneficial, they can become 'dark patterns', categorised here under the acronym FORCES (Frame, Obstruct, Ruse, Compel, Entangle, Seduce). Elsewhere, psychological principles like negativity bias, the curiosity gap, and fluency are exploited to make social content viral, while more covert tactics including astroturfing, meta-nudging, and inoculation are used to manufacture consensus. The power of these techniques is set to increase in line with technological advances such as predictive algorithms, generative AI, and virtual reality. Digital nudges can be used for altruistic purposes including protection against manipulation, but behavioural interventions have mixed effects at best.
