Science, ethnicity, and bias: where have we gone wrong?
The quality, quantity, and funding of ethnic minority research have been inadequate. One factor that has contributed to this inadequacy is the practice of scientific psychology. Although principles of psychological science involve internal and external validity, in practice psychology emphasizes internal validity in research studies. Because many psychological principles and measures have not been cross-validated with different populations, those conducting ethnic minority research often have a more difficult time demonstrating rigorous internal validity. Thus, psychology's overemphasis of internal as opposed to external validity has differentially hindered the development of ethnic minority research. To develop stronger research knowledge on ethnic minority groups, it is important that (a) all research studies address external validity issues and explicitly specify the populations to which the findings are applicable; (b) different research approaches, including the use of qualitative and ethnographic methods, be appreciated; and (c) the psychological meaning of ethnicity or race be examined in ethnic comparisons.
