Companies should pay more attention to introverts, according to Susan Cain.

The author of “Quiet: The Power of Introverts in a World That Can’t Stop Talking,” is turning her attention to the workplace, which she says is an unfriendly habitat for those with quiet dispositions.

“The primary message from companies to these introverts has traditionally been, ‘See that extrovert over there down the hall? Act more like her,’” Cain says.

This week, Cain announced the founding of the Quiet Leadership Institute, a business intended to help organizations harness the power of introverts and foster better communication between that group and their louder counterparts. In-person seminars and online courses cover the neurobiology of personality, introduce examples of successful introverted leaders and teach workers how to run meetings that won’t be dominated by the same loud colleagues who always speak up.

Cain says she’s advised Procter & Gamble Co. and NASA among others, and adds that she’s fielded interest from firms in a variety of industries, especially those with big technical or creative workforces. She wouldn’t comment on pricing.
