  • Duncan J. Watts (PSC Research Associate) was featured in Penn Today and the Annenberg School for Communications news about research in Judgement and Decision Making. Watts and co-authors examine the relationship between success stories and false belief about success.

  • Duncan Watts (PSC Research Associate) was featured in Penn Today about political polarization during informal political conversation. New research, published in the Proceedings of the National Academy of Sciences, explore how the mechanisms behind intra-group receptivity can be applied to anonymous, informal political communication. The study shows that, by fostering feelings of closeness through incidental similarities, those with strong beliefs on either end of the political spectrum can begin to converge upon more moderate views.

  • Duncan J. Watts (PSC Research Associate) was featured in Penn Today and Knowledge@Wharton about recent work, published in PNAS, that examines the efficiency and effectiveness of individual and group work.
