BOSTON—A study released Tuesday by the Lyman Center for Policy Evaluation and Strategy may have uncovered a link between school-based education and human smartness.

"Based on these forms we had people fill out, and these charts we came up with, we're pretty sure exposure to education in early life is consistent with higher levels of smartness-having overall," said Brent Shale, one of the study's coauthors. "Also, we figured out that the more educated-er people are, the better they are at doing complicated stuff like filling out forms and understanding charts."

If the study results are corroborated, the researchers say, it could mean "a whole new understanding of, you know, what smartness even is."
