“What you see in discourses about cycling is the absolute classic 1960s and 1970s social psychology of prejudice,” he explains. “It’s exactly those things that used to be done about minority ethnic groups and so on – the overgeneralisation of negative traits, under-representation of negative behaviours by one’s own group, that kind of thing. It’s just textbook prejudiced behaviour.”
