Watching YouTube Videos Makes Us (Mistakenly) Think We’ve Mastered a Skill

Watching YouTube videos, Instagram demos, and Facebook tutorials may make us feel as though we’re acquiring all sorts of new skills but it probably won’t make us experts, according to anyone who has ever attempted a Pinterest project — as well as to new research published in the journal Psychological Science.

“The more that people watched others, the more they felt they could perform the same skill, too — even when their abilities hadn’t actually changed for the better,” says study author Michael Kardas of The University of Chicago Booth School of Business. “Our findings suggest that merely watching others could cause people to attempt skills that they might not be ready or able to perform themselves.”

Kardas and co-author Ed O’Brien conducted a series of six experiments to find out whether watching videos without practicing the demonstrated skills can actually improve our ability to perform them. In one online experiment, the researchers assigned 1,003 participants to watch a video, read step-by-step instructions, or merely think about performing the ‘tablecloth trick.’ People who watched the 5-second video 20 times were much more confident in their ability to pull off the trick than were those who watched the video once. However, people who simply read or thought about the trick for an extended period of time did not show this confidence boost. These results provided initial evidence that repeated viewing may lead people to an inflated sense of competence.

To find out whether this perception is borne out by actual performance, Kardas and O’Brien tested a group of 193 participants on their dart-throwing abilities. Those who watched a demo video 20 times estimated that they would score more points than those who saw the video only once; the high-exposure group also predicted they would be more likely to hit the bull’s-eye and reported they had learned more technique and improved more after watching the video.

But these perceptions did not line up with reality: People who watched the video many times scored no better than those who saw it once.

Kardas and O’Brien found evidence for this phenomenon in other domains, including doing the moonwalk, playing a digital computer game, and juggling. The more participants watched others perform these skills, the more they overestimated their own abilities.

Why does repeatedly watching a video breed such overconfidence? Participants who watched a variation of the tablecloth trick video that did not show the performer’s hands evidenced no exposure-related overconfidence, suggesting that people may feel confident only when they can track the specific steps and actions in performing a skill.

“We see this as a potentially widespread phenomenon, given that people have daily access to outlets for watching others perform,” Kardas says. “Anyone who goes online to look up tips before attempting a skill — from cooking techniques to DIY home repairs to X Games tricks — would benefit from knowing that they might be overconfident in their own abilities after watching, and should exercise caution before attempting similar skills themselves.”
