Overconfidence linked to one's view of intelligence
Those who think intelligence is fixed have confidence exceeding their ability
Washington State University

Washington State University researcher Joyce Ehrlinger has found that a person's tendency to be overconfident increases if he or she thinks intelligence is fixed and unchangeable.

Such people tend to maintain their overconfidence by concentrating on the easy parts of tasks while spending as little time as possible on the hard parts of tasks, said Ehrlinger, a WSU assistant professor of psychology. But people who hold a growth mindset--meaning they think intelligence is a changeable quality--spend more time on the challenging parts of tasks, she said. Consequently, their levels of confidence are more in line with their abilities.

"A little bit of overconfidence can be helpful," said Ehrlinger, "but larger amounts of overconfidence can lead people to make bad decisions and to miss out on opportunities to learn." The researchers note that overconfidence is a documented problem for drivers, motorcyclists, bungee jumpers, doctors and lawyers.

"We know that students' beliefs about intelligence are very consequential in the classroom and that interventions that teach students a growth mindset lead to improvements in their grades," said Ehrlinger. "We also know that being overconfident keeps people from learning. You have to understand and acknowledge what you don't yet know in order to truly learn. This research suggests that part of why growth mindsets improve learning might be because they lead people to better understand what they do and what they do not know."

"Education is perhaps the best way to advance opportunity," she said, "and emerging evidence suggests that the benefits of teaching a growth mindset for improving grades are particularly strong for students in stigmatized groups based on race or gender."
