Madon, S., Guyll, M., Aboufadel, K., Montiel, E., Smith, A., Palumbo, P., & Jussim, J. (2001). Ethnic and national stereotypes: The Princeton trilogy revisited and revised. Personality and Social Psychology Bulletin, 27, 996-1010.

Three studies assessed changes in the content, consensus and favorableness of ten ethnic and national stereotypes by replicating and extending the Princeton trilogy (Gilbert, 1951; Karlins, Coffman & Walters, 1969; Katz and Braly, 1933). Results indicated that over the past 60 years, almost all of the ethnic and national stereotypes that were examined had changed in content, and more than half had changed in consensus. Most changes in consensus reflected increases, rather than decreases, suggesting that modern members of stereotyped groups may confront stereotypes more frequently than did previous members of stereotyped groups. However, the damaging effects that consensual stereotypes can have on members of these groups may be tempered by the finding that most of the stereotypes became more favorable. These results are discussed in terms of changing social roles, intergroup contact and stereotype accuracy.
