Top and Bottom State Ranking Snapshot
When states are ranked by average IQ, Massachusetts usually appears near the top, while Mississippi often appears near the bottom. The gap is meaningful at a population level but should not be applied to individuals.
Rankings are most useful when they lead to better questions: which states invest more in education, reduce childhood poverty, and support cognitive development?
Why Rankings Change by Source
Different state IQ rankings use different datasets, modeling assumptions, years, and proxy variables. That means exact rank order may change, especially among states with similar estimates.
A reliable article should show context rather than pretending every decimal point is final.
