Most things are not sudden as you first thought, you just weren’t paying attention. When we want to look and feel like we are all headed in the same general direction. The trap is to pay no attention to the particular.
The particular slows us down, threatens to take us in a different direction, and magnifies our mistakes. It’s little wonder it doesn’t appear on many agendas.
I wrote a paper whose results I analysed using the “95% limits of agreement”. We would do well to remember to spend some time testing our limits of agreement. Far better than creating an illusion of agreement.
