Zach Hambrick on Psychometrics and the Science of Expertise – #28

MSU Psychology Professor Zach Hambrick joins Corey and Steve to discuss general cognitive ability, the science of personnel selection, and research on the development of skills and expertise. Is IQ really the single best predictor of job performance? Corey questions whether g is the best predictor across all fields and whether its utility declines at a certain skill level. What does the experience of the US military tell us about talent selection? Is the 10,000 hour rule for skill development valid? What happened to the guy who tried to make himself into a professional golfer through 10,000 hours of golf practice?

[BONUS] – Left and Right at MSU – #27.5

Steve and Corey talk about political polarization and bias on campus with student editors of MSU’s dueling political blogs. The left-leaning students argue that the media has blown controversies over student politics out of proportion, while the conservative writers maintain the they do not feel comfortable expressing their views in many classes. Corey asks how beneficial is it to be white in America? Is the University as bastion of open debate no longer viable, especially in the current economic environment?

Rebecca Campbell on Identifying Serial Perpetrators, Rape Investigations and Untested Rape Kits – #18

Dr. Rebecca Campbell is a Professor of Psychology at Michigan State University, whose research focuses on violence against women and children with an emphasis on sexual assault. Steve and Corey discuss her recent National Institute of Justice-funded project to study Detroit’s untested rape kits. Dr. Campbell describes the problem of untested kits and her work with police departments around the country to reduce the backlog. She explains how the use of the national CODIS database has led to sharply higher estimates of the proportion of rapes committed by serial perpetrators and how many rapists appear to be criminal “generalists”, committing a wide range of offenses. She describes the dynamics of sexual assault investigations, the factors that lead police to put more effort into investigating certain cases over others, and how common ways of questioning women can lead them to disengage from the process. Other topics include the incentives at work in law enforcement, the slow pace at which new research in DNA testing and treatment of victims is incorporated into police training, and Dr. Campbell’s efforts to engage with law enforcement agencies to improve investigative practices.
