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?ResourcesTranscriptScience of ExpertiseZach Hambrick (Faculty Profile)Armed Services Vocational Aptitude BatteryProject 100,000 (1960s DoD Program)Test Validity Study Report (CLA)The Validity and Utility of Selection Methods in Personnel Psychology Announcing this for some friends at Mechanize - a startup that builds environments for training and evaluating frontier LLMs. Its customers include the top AI labs, and it has contributed to the breakthrough in coding capabilities of frontier models. Mechanize is hiring! https://mechanize.work/b/hsu Compensation is extremely competitive.
