Here's why watch most online tutorials are a waste of time

Sorry. But this Ted Talk does not make you smarter.


With as much information on the internet, we often feel like if you can learn just about anything to simply click on a video. Indeed, watching TED negotiations on a regular basis is something that people often boast, as if listening to the Dalai Lama or Bill Gates has brought them together with wealth or divinity.

On aNew study published inPsychological scienceHowever, it seems that the feeling of expertise we all get to watch tutorials is dangerously invasive.

Michael Kardas from the University of Chicago Booth School of Business and Co-author Ed O'Brien recently conducted a series of six experiences to determine how much these teaching videos were really effective.

In an experiment, they asked 1,003 participants to watch a video, read instructions or determine themselves how to perform the "tower"Use of the inertia property to shoot a tablecloth of a table without breaking a single piece of China. People who looked at the video 20 times or more were much more confident in their ability to remove it than those who 'had seen once or simply read the instructions or think about how to do it.

All you have to do is check all"Top of the tablecloth fails"Videos on YouTube to see that it was in no case the case.

Another experience, this time on dart-throwing, with 193 volunteers made similar results. A group looked at a video on how to hit a bull eye 20 times or more, while another group saw only the video once. As before, the group who looked at the video of the dozens of times said that they had gained a greater competence of dart games and were more likely to hit a bull eye than the control group. However, when put into practice, researchers found that it was not the case.

The researchers made similar experiences to play computer games, making the Moonwalk and juggling and received similar results. In each case, people who looked at a video of tens of times had a sense of confidence too qualified to complete the task to accomplish.

"Our results suggest that simply watching others could get people trying to try skills they may not be ready or capable of happening," said Kardas. "Whoever goes online to search for advice before attempting a skill - from the competence of cooking techniques to the repairs of the house of DIY to X game tricks - would benefit from knowing that they might be too confirmed in their own abilities after Surveillance and should be cautious before attempting similar skills. themselves. "

This is particularly true of some of the"Challenges" that adolescents, especially, post on social mediaNowadays, some can be dangerous to attempt without skills or prior knowledge. The old adage remains true: only the practice makes perfect. But remember: YouTube is always incredibly useful. In fact, he led aContractor to earn more than $ 16 million last year.
