According to Amy Chua and Jeb Rubenfeld, Yale law professors and authors of What Drives Success? A New York Times Sunday Review feature article, success in certain ethnic groups has to do with three underlying principles: 1) A superiority complex 2) An inferiority complex 3) Impulse control. For instance, believing that certain groups are chosen, better than or more elite can add extra confidence for individuals to persevere when times are tough. Feeling not good enough, not smart enough or not successful enough can add extra drive or motivation. Without the ability to delay gratification or learn to control one’s impulses, people won’t work hard enough in the now to secure longer term success. This article is very interesting and worth considering. Some statistics are especially interesting like Nigerians who make up less than one percent of the Black population in the United States yet in 2013 nearly one quarter of the black students at Harvard Business School were of Nigerian ancestry.
