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.

Air India Express cancels 74 flights due to cabin crew shortage; to operate 292 flights
Mumbai (PTI): Faced with cabin crew shortage, Air India Express on Thursday cancelled 74 flights and said Air India will operate services on 20 of its routes to minimise disruptions.
A section of cabin crew has reported sick to protest against alleged mismanagement at the airline, which has resulted in the cancellation of more than 90 flights since Tuesday night.
"We will be operating 292 flights today. We have mobilised all resources and Air India will support us by operating on 20 of our routes. However, 74 of our flights stand cancelled and we urge our guests booked to fly with us to check if their flight is affected by the disruption before heading to the airport," the airline said in a statement.
In case their flight is cancelled or delayed beyond three hours, the carrier said the passengers may opt for a full refund or reschedule to a later date without any fees.
The number of cancelled flights at 74 translates to around 20 per cent of the airline's scheduled daily flights.
Earlier in the day, sources said the airline has issued termination notices to 25 cabin crew members who had reported sick and asked others to join back for duty by 4 pm on Thursday.
Against this backdrop, Air India Express said it is taking appropriate steps against certain individuals.
"While we will continue to engage with our cabin crew colleagues with a commitment to address any concern, we are taking appropriate steps against certain individuals as their actions have caused grave inconvenience to thousands of our guests," it added.
