One definition of insanity is doing the same thing over and over again and expecting a different result. So if you are wanting a different result you have to change what you are doing. Or else there is that whole insanity thing staring you in the face.
In the Power of Habit the author Charles Duhigg links to the insanity (se above) of people expecting to change an outcome without changing the input or process. In the book these three points in the process are called Cue - Routine - Reward.
Simple, yet complex. As in any endeavour to deconstruct or reverse engineer anything to do with humans, the devil is in the details. What looks like something simple upon first observation, becomes increasingly complex as you peel away the layers. Humans are emotional and non linear. Plus just to make life interesting, and it does, we all sing along to a different playbook. One that is created by who you are, who your relatives are, who you run into in life, karma (had to throw that one in), your education and how you use all this to problem solve.
The Cue, Routine, Reward trilogy is an attempt to simplify the process and it works. The author gives us examples where changes to the routine can have sometimes dramatic changes. Sometimes the changes to the routine are small and sometimes they are large.
The author goes further in that he starts with humans and then moves onto organizations and societies using the same trilogy of cue, routine, and reward.
For anyone who wants at least a small chance of understanding why we do what we do, why organizations and society acts as it does this book will be insightful and instructive.
