Beijing is also rolling out a social credit system, using mass data collection to monitor and nudge citizens’ behaviour through strategic rewards and punishments. This is straight out of the dystopian TV series Black Mirror: in one episode, a woman is barred from buying a plane ticket due to her plummetting social ranking. In China, this is reality: one state-run media report admitted that 11 million train trips and 4 million plane trips have already been blocked due to low social credit scores. Such punishment can be triggered by misbehaviour ranging from the failure to pay back debts to spreading rumours, or even smoking or using expired tickets on trains. Conversely, a low credit score can be boosted by regular donations to charity. A senior official recently said that the system should ensure that “discredited people become bankrupt,” to underline the necessity of compliance.
