Some of the most challenging problems facing our world, such as the COVID-19 pandemic, require not just one field of expertise but a unified interdisciplinary approach. Or so explains a team of social scientists at Caltech in a new report published in the Proceedings of the National Academy of Sciences (PNAS). Likening the report to an op-ed piece, the lead author Anastasia Buyalskaya says that she and her team wanted to call attention to the “golden age of social science,” in which researchers are increasingly turning to new sources of data and interdisciplinary tactics to solve societal problems.
