110 | Neil Johnson on Complexity, Conflict, and Infodemiology

Physicists have traditionally simplified systems as much as possible, in order to shed light on fundamental properties. But small, simple parts build up into large, complex wholes. Are there new rules and laws of nature that apply specifically to the realm of complexity? This has been a popular question for a few decades now, and we have some answers but not as many as we would like. Neil Johnson is an expert on complex systems generally, and information networks in particular. We discuss how self-organization can arise from individual units following their own agendas, and how we can mathematically characterize such behavior. Then we talk about information networks in the modern world, including how they have been used to spread disinformation and find recruits for radical fringe groups.
