Humans have a default mechanism to recognize patterns. The same mechanisms that helped early humans avoid lions and other predators are still a part of our decision process. One of our in-built systems or tendency to see patterns where none exist. We try to create order from chaos. This isn’t surprising really — the brain is a wonderful pattern-recognition machine and it serves us phenomenally well in this way. Our brain has been designed to identify patterns to make better decisions.
