The Telegraph: How just one Facebook ‘like’ can be used to influence behaviour with targeted adverts. “Researchers used ‘mass psychological persuasion’ in an online ad campaign that saw sales rise by more than 50 percent. In an experiment that targeted 3.5 million people, the academics used just a single Facebook ‘like’ for each user to glean a psychological trait – whether they were introverted or extroverted. This characteristic was then used to tailor an ad for each consumer in an effort to influence them.”
