As reported in Forbes, a 8-year study on over 400 Chinese American families by Su Yeong Kim et. al. published in Asian American Journal of Psychology has found that not only is tiger parenting NOT common among those families studied but also that tiger parenting does NOT lead to the most ideal developmental outcomes, including academic success. In fact, most Chinese Americans families studied were of the supportive type that promoted many positive outcomes such as less depression and higher GPAs.
