ONLINE COVER Leaders are viewed as a valuable assets in mainstream society, with universities offering leadership degrees and bestselling books sharing leadership advice. However, there has been little rigorous empirical data attributing outcomes to leaders. To bridge this knowledge gap, Berry et al. developed a novel statistical method for testing leader effects called randomization inference for leader effects (RIFLE), which relies on fewer assumptions and leverages variations in data more effectively than methods from previous research. The researchers used this technique to estimate the impact of political leaders, CEOs, and sports coaches on various outcomes. They found that football, basketball, baseball, and hockey coaches at both the professional and collegiate level had the largest influence on outcomes. World leaders appeared to influence their nations' economies, with autocratic leaders exerting a particularly strong effect, while governors affected fiscal policy and crime but not economic prosperity and mayors seemed to affect none of these outcomes. CEOs of major U.S. companies did not appear to sway the success of their firms.[CREDIT: PIRANKA/ISTOCK]
