Where daylight saving time is implemented, SAT scores are lower:
Generating a novel scion to several obliquely related literature streams, this study examined a particular high-profile cognitive outcome of a sometimes controversial government policy, daylight-saving time. Controlling for socioeconomic status by proxy, the principal finding was a surprisingly strong negative relationship between imposition of the time policy in a geographic area and SAT scores of local high school students. The cautious conclusion is that the daylight-saving time policy should possibly be even more controversial for, at minimum, its economic implications.
