Why some people overestimate their abilities while others underestimate

Most people tend to predict that others will do better than they will on difficult tasks

A lack of confidence in our abilities on a given task or activity seems to stem from overestimating the abilities of others, according to a University of Alberta study.

The finding could offer leaders insights into how to counter self-doubt in the face of a difficult task.

Previous research has shown that most people tend to predict that they will outperform others for many tasks and activities, especially when tasks are easy. A classic example comes from a 1981 study of U.S. drivers in which 93 per cent claimed they were better than average.

However, most people tend to predict that others will do better than they will on difficult tasks.

In making sense of these seemingly contradictory findings, the study surveyed runners before a timed race about how they expected to do.

The researchers – Gerald Häubl, a marketing professor in the Alberta School of Business and the Ronald K. Banister Chair in Business, and Isabelle Engeler of the University of Navarra in Spain – chose a challenging mountain race, with uphill distances ranging from 10 to 78 km.

Controlling for age, gender and running experience, the researchers found that the runners who wrongly predicted that their finishing times would be better than average – those who were overconfident – were driven mainly by overestimating their own performances.

Meanwhile, runners who predicted they would perform worse than average – those underconfident in their abilities – had a solid understanding of their own performance but expected more from their competitors.

“Our work identifies two distinct sources of bias or two different reasons for why people might not be well-calibrated: they can be biased in their self-assessment, and they can be biased in their assessment of others,” said Häubl.

As well, the underconfident group was not only quite accurate in predicting their own performance; they also tended to be those who were better than average.

Häubl said underconfidence, which can manifest itself in the workplace as imposter syndrome, is often beneficial, particularly if it motivates people to work harder.

“The problem with underconfidence, however, is that it can prevent people who actually have the potential to excel at something – a particular job or career – from even trying because they falsely believe there are many others who are better than they are.”

Likewise, individuals who overestimate their performance tend to be those who are worse than average.

“This latter result bears parallels with prior research showing that people who are unskilled tend to overestimate their performance,” said Häubl.

This overconfidence, he said, can be good or bad, depending on whether it translates into higher or lower motivation and thus a desired outcome.

“Some of humankind’s greatest achievements were probably fuelled by some form of overconfidence. But then, so were some of humankind’s most spectacular failures,” he said.

“In very general terms, well-calibrated confidence, based on an accurate assessment of both one’s own and others’ abilities, is what people should strive for.”
