How can we take the confounding variable of stereotype threat out of an experiment that measures intelligence?
a. Use a randomied control trial design with an equal distribution of participants across conditions (stereotype threat vs. non-stereotype threat).
b. Implement a manipulation check to assess the effectiveness of stereotype threat induction and control for it in the analysis.
c. Utilie a double-blind procedure where both the experimenter and the participants are unaware of the stereotype threat condition.
d. Use a diverse sample of participants to ensure that any potential stereotype threat effects are not specific to a certain demographic group.
