The Grey Thinking CAP is the Metacognition Cap.
At a leadership convention in Melbourne I was asked to add one more cap (or hat) to the original 6 thinking caps developed by SOT in 1983.
I added the 7th Cap for Metacognition which is the Grey Thinking Cap/Hat. The Metacognition Cap is the Wisdom Cap.
Of all the Thinking Hats–White, Black, Yellow, Red, Green, Blue–the Grey Hat (or Cap) is also the Senior Hat.
(Master Vincent van Gogh’s Self Portrait with Grey Hat, Paris, 1887)
EXPERIENCE + KNOWLEDGE = WISDOM
wisdom n. experience and knowledge together
with the power of applying them critically or practically
– Oxford English Dictionary
FROM BLACK HAT TO GREY HAT
is all about the escape
from judgmental thinking to wisdom.
Survival is clever and requires intelligence. Long term survival endows wisdom and this is a very clever thing, indeed
From the hard-won accomplishment of longevity emerges broad experience and special knowledge. It cannot be taught. It also offers a deep appreciation of the role that sheer random luck plays in long term survival.
I am dedicating this hat to my father who was one of the wisest people I have ever known. He had a great deal of life experience. In WWII he had served and survived in two theatres of war in the Middle East and in New Guinea.
Before the war, in Melbourne, he received a classical education. He was widely read, had a great deal of knowledge and common sense and was known for his generosity, his cheerful demeanour and lively sense of humour. He was also very lucky. He survived bowel cancer, completely, and other narrow escapes.
Dad used to always say, “Nobody’s perfect”. How wise he was!
