Originally called the Scholastic Aptitude Test for Medical Students, Moss developed the readiness test as a way to curb high dropout rates in medical schools. The MCAT paved the way for other standardized admission exams, like the SAT, and the many sleepless nights college-bound students still endure in preparation. But Moss likely wouldn’t have minded that sleepless legacy: To Moss, a psychology professor at GWU, sleep was a useless habit. Both too little sleep and too much sleep have been associated with higher risks of disease and early death. Some studies found that too much sleep has a higher association with poor health outcomes than too little sleep.
