"That’s such a hard question,” Gina Neff, a sociologist at the Oxford Internet Institute, responds when asked what social science research or thinker most influenced her. “It’s like a busman’s holiday for an academic, because so many things have influenced my thinking.” Her answer, by the way, was Ulrich Beck’s concept of the risk society, as explained in this 1986 book. In this montage drawn from the last two years of Social Science Bites podcasts, interviewer David Edmonds poses the same question to 25 other notable social scientists. For many of the guests, the answer proves difficult to pin down to just one person or work (“That’s like asking who’s your favorite kid,” was David Halpern’s first response). For a few guests, the response is instant. “A simple answer, really,” replies Rupert Brown, naming a fellow social psychologist, Turkish-American Muzafer Sherif, and his work in the 1950s. And sociologist Les Back, too, answers instantly: “Don’t even have to think about it: WEB DuBois’s The Souls of Black Folk. DuBois is the writer who captures both the heat and the passion of life and also the cool historical perspective and analysis in the most extraordinary compound of literary expression.” Back, in turn, was mentioned by one scholar: Kayleigh Garthwaite as her great influencer. A number of the guests cited titans from the early days of social science – Max Weber, Karl Marx, Pierre Bourdieu, Emile Durkheim, while others named modern-era titans like Stephen Pinker, Daniel Kahneman, Jonathan Haidt or Jean Piaget. And many named creators of the new canon – Jim Scott cited A.P. Thompson’s Making of the English Working Class, Alondra Nelson picked Troy Duster’s Backdoor to Eugenics, and Gurminder  Bhambra tabbed Danielle S. Allen’s Talking to Strangers: Anxieties of Citizenship since Brown v. Board of Education. And no such list would be complete without a wild card, and for that we turn to Michelle Gelfand, who turned to Herodotus’ The Histories and the lessons a 2,500-year-old post-mortem of an ancient war can teach us today: “He was a brilliant cross-cultural psychologist … he also had a really interesting observation — that all humans are ethnocentric. They don’t just think that their culture is different, they think it’s better.” This is the fourth collection in this series (and the 100th Social Science Bites podcast).
