Today bots, trolls and cyborgs could create the simulation of a climate of opinion, of support or hate, which was more insidious, more all-enveloping than the old broadcast media. And this simulation would then become reinforced as people modified their behaviour to fall in line with what they thought was reality. In their analysis of the role of bots, researchers at the University of Oxford called this process ‘manufacturing consensus’. It is not the case that one online account changes someone’s mind; it’s that en masse they create an ersatz normality. Over the decades there have been many studies showing how people modify their behaviour to fit in with what they think is the majority point of view. In 1974 a German political scientist and pollster called Elisabeth Noelle-Neumann looked into research that showed how people will go along with the majority opinion in order to fit in. The need to belong is one of the deepest human inclinations, Noelle-Neumann argued, and people are motivated by fear of isolation; that is why exile, expulsion from the group, is one of the oldest forms of punishment.
