7. Iowa
Average SAT Score: 1098
Iowa maybe has a higher IQ average then the previous entry, but still lower than the 8th, with its mark being 103.2. You are probably noticing that the differences are pretty small both in IQ and SAT scores, but this should be expected since these are the top 10 smartest states in America by SAT scores, and not all 50 states. In case you are wondering, the state with the lowest SAT score of 963 is West Virginia, and its average IQ is not among the 10 worst with the mark hitting 98.7.
