This investigation employed a longitudinal design to examine the influence of a one-shot growth mindset intervention on ninth-graders' implicit beliefs about intelligence and related achievement goals in four different samples. The intervention conformed to characteristics of 'wise interventions'. Participants' incremental beliefs about intelligence and achievement goals were measured prior to the intervention and at several subsequent points in time following the intervention. Our results provide modest evidence that the one-shot intervention can promote incremental views of intelligence and reduce the prevalence of performance goals when used at scale.
