We Need More Tests, Not Fewer, argues John D. Mayer, a professor of psychology at the University of New Hampshire and author of “Personal Intelligence: The Power of Personality and How It Shapes Our Lives," in a recent Op-Ed in the New York Times.
He begins by talking about how effectively tests capture people's later accomplishments, as well as more elusive aspects of cognitive potential and personality:
Research indicates that mental tests do predict people’s patterns of behavior in consequential ways. For instance, graduate students’ G.R.E. scores are correlated with the ratings faculty members later give them, their likelihood of remaining in a program, and the impact of their publications (as measured by citations). And tests like the NEO-PI-R that measure social and emotional traits like conscientiousness and agreeableness can predict a person’s longevity and likelihood of staying married.
In addition, tests are our only way to study and attempt to understand ineffable mental qualities like intelligence, openness to experience and creativity. They help make the mysteries of mental life tangible. Neuroscientists use them to discover who excels in particular mental abilities, and to try to identify the parts of the brain responsible.
What if, in addition to the SAT, students were offered new tests that measured more diverse abilities? For future artists or musicians, there are tests that measure divergent thinking — a cornerstone of creativity largely ignored by the SAT. For future engineers, there are tests that measure spatial reasoning. And new measures of “personal intelligence” — the ability to reason about a person’s motives, emotions and patterns of activities — may also tell us something important about students’ self-knowledge and understanding of others.
