When we see only what we expect to see, we may miss what we should see.
An example, a study was undertaken at an airline desk. An agent began checking one traveller's tickets after a while he dropped a ticket and bent down to pick it up. A different agent who had been hidden behind the counter, stood up and continued checking tickets. Many of the travellers didn't notice the change. They were expecting a ticket agent, as long as one was there, their eyes were satisfied.
Think of how this could be affecting your behaviour. Do you see what you want to see? Are we missing a simple answer, or cutting through the complexity because we are used to the complex system. Are you missing a development opportunity in a team member skills?
Open your eyes, see what is there not what you want to see
