New in the APS Observer: Nathan on the Stability of Psychopathy, David on the Stability of Intelligence

The October APS Observer is out with an essay by Nathan, “Once a Psychopath, Always a Psychopath?” on people who “commit horrific crimes, experience little guilt or remorse, and then commit similar crimes again.” What is their potential for change, and how can we teach students about them?

In the same issue, I offer “The Story of My Life and Yours: Stability and Change.” It’s a celebration of what I regard as one of the great studies in the history of psychological science . . . Ian Deary and colleagues’ discovery of the intelligence scores of virtually all Scottish 11-year-olds in 1932, and then their retesting of samples of that population up to age 90.  The bottom line:  our lives are defined by a remarkable stability that feeds our identity, and also by a potential for change that enables us to grow and to hope for a brighter future.
