The story I heard happened in the 1950s-60s, at 50-60x at Bell Telephone in the USA
Top management of the corporation noticed a majority of their managers were formerly engineers and often they don't have enough initiative and lacked diversity.
They decided to fix this by creating the Bell Institute of Humanistic Studies for Executives and running 10 month courses lectured by professors from Pennsylvania University. In these lectures they read books, visit concerts and museums, met with writers and musicians.
Those who finished this courses started read more, become more curious, confident and intellectually independent. On the other hand, they started spending less time at work, didn't take work at home and their efficiency & productiveness decreased by 8-10% annually. Instead, they preferred to spend this time with their families and enjoy life.
At sixties, this institute was closed and company growth normalized.
Is this story true or false?
