YouTube videos won't make you an expert overnight
New York: Watching YouTube videos, Instagram demos and Facebook tutorials may boost your confidence in performing a task but it probably would not make you an expert overnight, suggests new research.
Social media platforms have made it easy to record, share, and access instructional videos, but merely watching them without practicing the demonstrated skills may not actually improve our ability to perform them, according to the findings 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," said study author Michael Kardas of The University of Chicago Booth School of Business in the US.
"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 said.
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," which involves pulling a tablecloth off a table without disturbing the place settings on top.
People who watched the five-second video 20 times were much more confident of 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.
Those who watched a demo video 20 times estimated that they would score more points than those who saw the video only once -- this high-exposure group also predicted that they would be more likely to hit the bull's-eye and reported that 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.

Deadline Trump announced for Iran to begin ceasing fire against Israel passes
Dubai (AP): Iranian state television reported on Tuesday that a ceasefire had begun in its war with Israel, even as Israel warned the public of a new missile barrage launched from Iran.
It wasn't immediately possible to reconcile the messages from Iran and Israel on the 12th day of their war.
Iranian state television announced the ceasefire in a graphic on screen, not immediately acknowledging the new missile barrage coming after the deadline set by President Donald Trump in his earlier ceasefire announcement.
A series of Iranian barrages before the ceasefire deadline killed three people and injured at least eight others in Israel, rescuers said.
