According to a study of 1,500 people around the world, they hinder innovation and the production of collaborative ideas.
Remote exchanges by videoconference, which have become essential since the explosion of teleworking, hinder the production of collaborative ideas, according to a study of 1,500 people around the world published on Wednesday. During the Covid-19 pandemic, technologies such as Zoom, Teams or Skype enabled millions of employees to hold remote meetings, with sound and image.

This virtual collaboration could well continue, recent polls showing that in the United States for example, 20% of working days will take place at home after the end of the pandemic, underlines the study published in the journal Nature. Their authors, marketing experts for the American universities of Columbia and Stanford, wanted to know the effects of this abandonment of face-to-face interactions on innovation, in other words the ability to generate new ideas during an exchange – the “brainstorming“. They conducted initial laboratory tests, with 602 voluntary participants (students) paired randomly. The pairs were either arranged face-to-face in the same room or separated in two distant spaces, talking to each other via video call. Each team had 5 minutes to find creative uses for products – a frisbee and bubble wrap. Then had to select his most creative idea.
The experience was replicated in companies with 1,490 engineers in Finland, Hungary, Portugal, India and Israel: during dedicated workshops within their premises, the groups were invited to propose innovative products for their companies, specializing in telecommunications. Result: In-person interactions produced about 15% more ideas than virtual interactions, and 13% more creative ideas. Good news, however, for Zoom, Skype and Teams: when teams had to choose their best idea, virtual exchanges proved to be just as fruitful as face-to-face, and sometimes even slightly more. The researchers deduced that only creativity was inhibited by video calls, when other skills seemed unaffected.
Too much screen focus
But why ? Previous research has established a neurological link between vision and concentration, and shown that, paradoxically, “people are more creative when they are less focused“Explains Melanie Brucks, professor of marketing at Columbia Business School, co-author of the study, in a video presentation of her work. To test it, she equipped her “guinea pigsof an eye tracking device. And thus was able to verify that the virtual partners spent almost twice as much time looking at each other as their face-to-face counterparts.

Video calls focused attention on a limited space – the screen – thereby limiting the cognitive process of creation. Whereas face-to-face, people shared a whole environment, “more conducive to branching thoughts generating new ideas“, develop the authors. Who suggest not eliminating virtual collaborations – which have their advantages – but reserving them for certain specific tasks, favoring presence in the office for brainstorming. And not to get too distracted like this group of engineers from Poland, whose company had organized the workshops in a hotel for a seminar. The participants were obviouslymore concerned about the coffee and cookies served at the hotel barthan by the experimental protocol, from which they were ultimately excluded.
