Historically, research on the determinants of intelligence quotient (IQ) has led to many questions: Is IQ fixed or fluid? Is IQ an innate quality of the human brain or do intelligence tests define IQ? If testing defines IQ, does this mean that changes in intelligence testing will result in changes in IQ? Utilize the module resources and your own research to explain whether you believe IQ to be fixed or fluid and what you believe to be the most valid predictors of IQ and why. Applying a holistic lens, clearly state what you believe are the biopsychosocial implications of viewing IQ as something that is unchangeable or as a product of learning, experience, and development.
