ABSTRACT In 2014, Macnamara, Hambrick, and Oswald published a meta-analysis of studies questioning the strength of the association between deliberate practice and performance. In this brief report, the correlation reported by Macnamara et al. (2014) is placed in the context of other well-known associations. Additionally, a re-analysis of the studies included in Macnamara et al. (2014) was conducted. Taken together, the evidence suggests that deliberate practice is a potent and reliable method for improving performance.
