"In perhaps the creepiest example, Facebook applied for (and received, last year) a patent for a tool called Techniques, for emotion detection and content delivery. It would use the camera in your phone to take pictures of you as you scroll through content. Facebook would then use facial analysis to measure how much you did or did not like the content in question, so as to determine what kind of stuff to send your way."
@Gargron "The conscious and intelligent manipulation of the organized habits and opinions of the [public] is an important element in democratic society. Those who manipulate this unseen mechanism of society constitute an invisible government which is the true ruling power of our country."
– Edward Bernays, Propaganda (1928) p. 37
