Afriend majoring in anthropology is critical of psychological research because it often ignores the influence of culture on thoughts and actions. you point out that
a. there is very little evidence that cultural diversity has a significant effect on specific behaviors and attitudes.
b. most researchers assign participants to experimental and control conditions in such a way as to fairly represent the cultural diversity of the population under study.
c. it is impossible for psychologists to control for every possible variable that might influence research participants.
d. even when specific thoughts and actions vary across cultures, as they often do, the underlying processes are much the same.
