When to Rethink Gut Instincts
Panicked test-takers are often advised to go with their first impulse when answering tough questions on multiple-choice exams such as the SAT. But a new study has found that this strategy may actually hurt performance. That’s because, on average, test takers most often change answers from incorrect to correct, improving their test scores. This “first instinct fallacy” persists says Justin Kruger, a psychologist at the University of Illinois at Urbana-Champaign because instances when we change an answer from right to wrong loom larger in memory and lead to frustrated “if only” self-recriminations. Changing an answer from wrong to right is not as memorable, creating the illusion that it happens less often. The study appeared in an issue of the Journal of Personality and Social Psychology.
