Question: We live in a society obsessed with test scores and
We live in a society obsessed with test scores and maximum performance. Think of the SAT, ACT, GRE, GMAT, and LSAT. Though they take only a few hours, they are supposed to give schools and companies a snapshot of a student’s abiding talents. But these tests are often spectacularly bad at forecasting performance in the real world. The SAT does a decent job (r2 5 .12) of predicting the grades of a college freshman. It is however less effective at predicting achievement after graduation. LSAT scores bear virtually no correlation to career success as measured by income, life satisfaction, or public service. What does the r2 mean in this context? Is it ethical for colleges to base admissions and financial aid decisions on scores alone? What role do these tests take at your own school?
