Think you live in a smart state? The numbers might say otherwise.
Using the most recent IQ data from 2025, we’ve ranked which states rise to the top—and which fall flat.
Some of the results are expected (hello, Massachusetts), while others might surprise you.
Whether it’s education, environment, or just good genes, here’s how America’s states stack up when it comes to raw brainpower.

Top of the class. With elite schools, high income, and historic academic culture, Massachusetts claims the crown as the smartest state in the country.
New Hampshire (IQ: 104.2)
Right on Mass’s heels, New Hampshire pairs strong public education with high civic participation. It’s small, but sharp.
North Dakota (IQ: 103.8)
Fewer people, more brain cells. ND’s mix of solid schooling and low distractions keeps it in the top tier.
Vermont (IQ: 103.8)
Quiet, green, and brainy. Vermont’s progressive policies and education-first approach pay off in the IQ rankings.
Minnesota (IQ: 103.7)

Maine (IQ: 103.4)
Coastal calm and brainy kids. Maine stays smart thanks to consistent investment in public schools and tight-knit communities.
Montana (IQ: 103.4)
Rural doesn’t mean dumb. Montana’s among the highest in average IQ despite its spread-out population.
Iowa (IQ: 103.2)
Known for its farmland, but don’t overlook the sharp minds. Iowa’s public education system is a quiet powerhouse.
