A California based real-estate group has released a map that purports to show the average IQ levels of individuals in each state.

Movoto said in a blog post that they analyzed 500,000 unique tweets from around the country to compose the map, using a computer algorithm to score tweets based on spelling, grammar and word choice.

The group found that California, New Mexico and Mississippi were among the states with the lowest average level of intelligence.

On the other end? Montana, North Dakota, Minnesota, New Hampshire and Massachusetts were among states with the highest IQ’s.
