There has also been an issue with minority populations becoming educated because to a fear of being accused of "Acting White". It is a hard definition to pin down, however, this is a negative term predominantly used by African-Americans that showing interest in one's studies is a betrayal of the African-American culture as one is trying to be a part of white society rather than staying true to his/her roots. Roland G. Fryer, Jr., at Harvard University has noted that, "There is necessarily a trade-off between doing well and rejection by your peers when you come from a traditionally low-achieving group, especially when that group comes into contact with more outsiders." Therefore, not only are there economic and prehistoric causes of racial educational segregation, but there are also social notions that continue to be obstacles to be overcome before minority groups can achieve success in education.
