Exploring the Challenges of Replicating Findings in Social Sciences

Jack visits with Mark Robert Rank, author of the forthcoming book, The Random Factor: How Chance and Luck Profoundly Shape Our Lives and the World Around Us."What shapes our economic fortunes? Perhaps what immediately comes to mind are attributes such as education, skills or labour-market experience. Demographics such as age and your parents’ socioeconomic status might also be considered."Yet surprisingly, according to a wide range of social scientists, these factors are only able to explain about 35 per cent of the variance in earnings. In other words, 65 per cent of the differences in individual income defy our standard assumptions."— Quote from an essay by Dr. Rank.
