The $67.5 million wasted on stereotype threat research

One popular topic in psychology when discussing test performance is the idea of stereotype threat. First proposed by Claude Steele and Joshua Aronson in 1995, the stereotype threat is phenomenon where a person who belongs to a stereotyped demographic group performs in accordance with the stereotype after being reminded of it.

Thoughts on low national IQs, intellectual disability, and data quality

Biology has evolutionary theory as a powerful framework for understanding everything from ecology to genetics. Chemistry has atomic theory, which

Standardized tests: NOT designed for standardized minds

Lewontin’s bait-and-switch: A strategy to undermine genetic explanations of behavior
