wisdom n. experience and knowledge together
with the power of applying them critically or practically
Oxford English Dictionary


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.

The Grey Thinking Hat is for Wisdom.

The experience of surviving for a complete generation through childhood, adolescence and adulthood endows knowledge and perspective that a young brain cannot match.

To achieve 50 years of survival, through two or more generations, allows the brain to build a database of experience which offers a perspective of history, an understanding of long term consequences, a faculty for prediction and a wisdom that cannot be acquired in any other way. It takes half a century!

(Master Vincent Van Gogh’s Self Portrait with Grey Hat, Paris, 1887)

Grey Hat Thinking is the ability to see consequences, immediate, short term and long term. It is the ability to look back over history and to see forward into the future. To understand cycles, passages of time, the passing of fashions, eras, eons and the many possible futures including extinction, the possibility of no future at all.

Grey Hat Thinking also means the wisdom to see other points of view. It includes the sagacity of patience to see beyond one’s own immediate viewpoint and the wisdom to see the viewpoints of others involved in situations: your partner’s viewpoint, your children’s, your children’s children, your neighbour’s, your customer’s, your enemy’s.

The wisdom of Grey Hat Thinking comes from long term survival.

It is the wisdom that emerges from the hard won, labour-intensive experience gained from having to solve life’s wide range of problems through multi-changing environments over several generations and for an extended period of time.

One of the well-known paradoxes of wisdom is expressed by Mark Twain’s admission: “When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much the old man had learned in seven years”.

Even though we may not be able to teach children to do Grey Hat Thinking we can still teach them to understand what it is–to recognise it–to appreciate it, to consult it, and to seek it our wherever it can be found.

Of all the original Thinking Hats–White, Black, Yellow, Red, Green, Blue–the Grey Hat is also the Senior Hat.

  1. Hi Professor Michael,
    if I was to contribute, I would propose some discussion at a point that describes what is called a long term survival. As I think on this I really understand it as some kind of awareness or conscience. And self conscience is one of the particularities of human beings.And also can be defined as the understanding of the influence of each act a person has in the hole complex society system we live on.
    I know it ain’t no new thing, but that’s it.

    Good luck w/ your new book!
