. What Factors Undermine Group Members' Performance on IQ Tests?

Self-Fulfilling Prophecy: A study conducted by Ovankina and colleagues (2011) found that people who were influenced by a self-fulfilling prophecy regarding their intelligence had significantly lower IQ scores. Gender Bias: Research from Sutton and Bahmani (2015) found that gender bias can have a negative influence on girls’ self-efficacy, which can in turn lead to lower IQ scores. Culture: Studies conducted by Delgado-Gaitan and Espinosa-Larran (2017) have shown that culture can play a large role in impacting IQ test scores. They found that those from culturally diverse backgrounds had lower IQ scores compared to their monocultural peers. Stereotype Vulnerability: According to research by Mueller and colleagues (2015), individuals who are exposed to negative stereotypes regarding their cultural group are likely to experience lower performance on IQ tests.
