Have the large monolithic organisations in which most of us work had their day? Is blindness the inevitable consequence of too much history, certainty and success. I think so.
We all have blind spots. Some of us work hard to see past them. Science and data can help. As a physicist I remember the huge effort needed to believe in quantum mechanics when this ran counter to my lived experience. The first step was to let go of everything I had previously learned about the way objects behave in the world - a deep knowledge that I'd acquired from my first breathing moments. It was deep knowledge and had served me well but it turned out to be wrong!
In the same way, organisations have blind spots. They too have deep knowledge which stops them being open minded and emotionally ready to accept other truths and other ways of doing things. They can't let go. They can't see themselves from an 'outside in' perspective. They can't innovate.
This makes me wonder if the innovators of this world are going to run to the open spaces - the cracks between organisations. Here there are no ingrained patterns of behaviour to overcome. There are no revenue streams to be protected and new ideas can flourish. (Necessity is the mother of invention as they say.) Perhaps it's easier to see things from an 'outside in' perspective in when you live outside yourself between the cracks.
