In a recent interview with Vox’s Ezra Klein, journalist and author Ta-Nehisi Coates argued that serious thinkers and writers should get off Twitter.

It wasn’t a critique of the 140-character medium or even the quality of the social media discourse in the age of fake news.

It was a call to get beyond the noise.

For Coates, generating good ideas and quality work products requires something all too rare in modern life: quiet.

He’s in good company.  Author JK Rowling, biographer Walter Isaacson, and psychiatrist Carl Jung have all had disciplined practices for managing the information flow and cultivating periods of deep silence. Ray Dalio, Bill George, California Governor Jerry Brown, and Ohio Congressman Tim Ryan have also described structured periods of silence as important factors in their success.

Recent studies are showing that taking time for silence restores the nervous system, helps sustain energy, and conditions our minds to be more adaptive and responsive to the complex environments in which so many of us now live, work, and lead. Duke Medical School’s Imke Kirste recently found that silence is associated with the development of new cells in the hippocampus, the key brain region associated with learning and memory. Physician Luciano Bernardi found that two-minutes of silence inserted between musical pieces proved more stabilizing to cardiovascular and respiratory systems than even the music categorized as “relaxing.” And a 2013 study in the Journal of Environmental Psychology, based on a survey of 43,000 workers, concluded that the disadvantages of noise and distraction associated with open office plans outweighed anticipated, but still unproven, benefits like increasing morale and productivity boosts from unplanned interactions.

But cultivating silence isn’t just about getting respite from the distractions of office chatter or tweets.  Real sustained silence, the kind that facilitates clear and creative thinking, quiets inner chatter as well as outer.

This kind of silence is about resting the mental reflexes that habitually protect a reputation or promote a point of view. It’s about taking a temporary break from one of life’s most basic responsibilities: Having to think of what to say.

Cultivating silence, as Hal Gregersen writes in a recent HBR article, “increase[s] your chances of encountering novel ideas and information and discerning weak signals.” When we’re constantly fixated on the verbal agenda—what to say next, what to write next, what to tweet next—it’s tough to make room for truly different perspectives or radically new ideas. It’s hard to drop into deeper modes of listening and attention. And it’s in those deeper modes of attention that truly novel ideas are found.
