If you’ve watched the TV show “CSI: Cyber” then you know a little bit about Mary Aiken. She’s a forensic cyber psychologist, and the fictional television program was inspired by her real life work advising law enforcement on virtual crime. Aiken says people take risks online they never would in the “real world”, a phenomenon that puts vulnerable populations at risk, particularly the young. In a new book, “The Cyber Effect”, Aiken explains how the act of going online changes our behavior in fundamental ways. From what happens in the “dark web”, to issues raised by digital selfies, to the growing problem of “cyberchondria” Aiken introduces us to some of the many ways our behavior changes online.
