People are worse at coming up with creative ideas during a video call compared to meeting in person, a recent study said, suggesting that workplaces should prioritize brainstorming sessions for the office.
The pandemic has changed the nature of office work, propelling a massive rise in videoconferencing that looks unlikely to abate as work-from-home arrangements become more entrenched across the world.
Seeking to find out how this huge change affects creativity, researchers in the United States studied nearly 1,500 employees of a telecommunications company in Finland, Hungary, India, Israel and Portugal.
In pairs, the employees－either in person or on a Zoom call－came up with as many creative ideas as they could for the company's products, then picked the best one.
The pairs who spoke in person came up with around 15 percent more, according to the study published in the Nature journal.
The researchers found similar results in an experiment involving more than 600 university students, who were also paired off and told to come up with creative ideas for either a frisbee or bubble wrap.
The in-person pairs came up with 14 percent more ideas.
However, it was not all bad news for Zoom, Skype and other videoconferencing apps.
Both sets of results found that video calls were just as effective for selecting the best idea, a decision which requires "cognitive focus and analytical reasoning", the study said.
To understand the difference, the researchers tracked the gaze of the participants.
"In the virtual condition, people are looking significantly more at their partner－almost double－at the expense of their broader environment," said the study's co-author Melanie Brucks, an assistant marketing professor at Columbia University, in a Nature video.
The study said: "Videoconferencing hampers idea generation because it focuses communicators on a screen, which prompts a narrower cognitive focus."
That kind of focus might help select the best idea－but hinder coming up with one in the first place.
"We're most creative when we're unfocused and free," Brucks said. "I always suggest turning off the camera during idea generation, so you can walk around, you can look around."
These results could inform how companies plan remote working, said the study－particularly in hybrid home-office setups where "it might make sense to prioritize creative idea generation during in-person meetings".
