Lynn's IQ Estimates and Anti-Racism
- Richard Lynn's national IQ estimates sparked controversy, raising concerns about racism and comparisons to intellectual disability.
- Scott Alexander addresses these concerns by arguing that Lynn's data, if accurate, supports an environmental explanation for IQ differences.
Environmental Factors and IQ
- If IQ is entirely environmental, Malawians should have significantly lower IQs than African Americans due to worse living conditions.
- Lynn's estimate of 60 for Malawi supports this, suggesting environmental factors play a significant role.
Functionality and IQ
- When comparing Malawians to the intellectually disabled, we often think of individuals with syndromes like Down syndrome, which have additional deficits.
- A person with a 60 IQ without these syndromes might appear more functional than expected.
