At a leadership convention in Melbourne I was asked to add one more cap to the original 6 thinking caps developed by SOT in 1983. I have designed the 7th Cap for Wisdom which is the Grey Thinking Cap.
The book will be published later this year.
Of all the Thinking Caps–White, Black, Yellow, Red, Green, Blue–the Grey Cap is also the Senior Cap.
EXPERIENCE + KNOWLEDGE = WISDOM
wisdom n. experience and knowledge together
with the power of applying them critically or practically
– Oxford English Dictionary
THE GREY CAP (US: GRAY)
is all about the escape
from judgmental thinking to wisdom.
