First among equals: Log data indicates ability differences despite equal scores

作者：

Highlights：

• Test-taking behavior in complex problem-solving (CPS) tasks differs across test-takers.

• We scrutinize the assumption that test-taking behavior is a valid indicator of ability.

• Students showed significant variance in behavior even without variance in CPS test scores.

• Behavior significantly predicted students' GPA.

• When adding intelligence, the relation behavior and GPA was reduced to negligible effects.
