Political scientist David Karpf talks about Cambridge Analytica, and about how their perception by many as masters of advanced digital influence (as portrayed in, for example, the documentary The Great Hack) is inaccurate and exaggerated. Dr. Karpf talks about the effects of political ads, about the role of social media and the internet in politics, and what he sees as the real problems we're facing as a modern society. He also talks about the time he made a tweet comparing Bret Stephens to a bedbug and crazy things ensued.
