Science, ethnicity, and bias: where have we gone wrong?

Area of Science:

• Psychology
• Sociology
• Ethnic Studies

Background:

• Ethnic minority research quality, quantity, and funding are insufficient.
• Scientific psychology's emphasis on internal validity over external validity hinders ethnic minority research.
• Lack of cross-validation of psychological principles and measures across diverse populations creates challenges.

Purpose of the Study:

• To analyze how scientific psychology's methodological focus impacts ethnic minority research.
• To propose improvements for conducting more rigorous and relevant research on ethnic minority groups.

Main Methods:

• Literature review and critical analysis of research methodologies in scientific psychology.
• Examination of the concepts of internal and external validity in the context of ethnic minority research.

Main Results:

• Psychology's overemphasis on internal validity has disproportionately impeded ethnic minority research development.
• Researchers face difficulties demonstrating rigorous internal validity due to un-cross-validated measures.
• This methodological bias limits the applicability and generalizability of psychological findings to ethnic minority populations.

Conclusions:

• Future ethnic minority research must prioritize external validity and clearly define applicable populations.
• Adoption of diverse research approaches, including qualitative and ethnographic methods, is crucial.
• Investigating the psychological meaning of ethnicity and race in comparative studies is essential for advancing knowledge.
