This experiment tested twenty 14 to 18-year-old gifted students from Newton High Schoolâ€™s gifted education program in Newton, Kansas. Despite scoring extremely high on intelligence tests, there is a wide range of grades and motivation between the students. To find the reasons for these discrepancies, subjects completed the NEO personality inventory, the SMALSI inventory, and a socio-demographic survey. The study found that motivation and agreeableness have a large impact on grades. Motivation is greatly affected by peer groups and other personality factors, while agreeableness is affected mainly by social factors. Peer groups had a substantial impact on the study as a whole, indicating that a social stigma could be an underlying factor.
