CITP Director Matthew Salganik was interviewed recently about the Fragile Families Challenge. As Salganik states in this interview: “The Fragile Families Challenge is a scientific mass collaboration designed to answer one question: how predictable are life trajectories? That is, given some data about a person, how accurately can we predict what will happen to that person in the future?” There are implications for policy makers interested in using predictive models for high-stakes decisions about people.
