The persuasive technology tricks espoused by Fogg include several related to social psychology: a need for approval, a desire for reciprocity, and a fear of missing out. Everyone wants to feel approved of by others. We want our posts to be liked. We want people to respond to our texts, emails, tags, and shares. The need for social approval is what made Facebook’s Like button so powerful. By controlling how often a user experiences social approval, as evaluated by others, Facebook can get that user to do things that generate billions of dollars in economic value. This makes sense because the currency of Facebook is attention. Users manicure their image in the hope of impressing others, but they soon discover that the best way to get attention is through emotion and conflict. Want attention online? Say something outrageous. This phenomenon first emerged decades ago in online forums such as The WELL, which often devolved into mean-spirited confrontation and has reappeared in every generation of tech platform since then.
Social approval has a twin: social reciprocity. When we do something for someone else, we expect them to respond in kind. Likewise, when a person does something for us, we feel obligated to reciprocate. When someone “follows” us on Instagram, we feel obligated to “follow” them in return. When we see an “Invitation to Connect” on LinkedIn from a friend, we may feel guilty if we do not reciprocate the gesture and accept it. It feels organic, but it is not. Millions of users reciprocate one another’s Likes and friend requests all day long, not aware that platforms orchestrate all of this behavior upstream, like a puppet master.
