We find that we cannot identify and weigh alternatives like we can when we are calm. Then, we quickly seize the solution so we can get on to the next problem. It feels right, and we feel like efficient problem solvers. But from past experience, we all know that this approach to decision-making is seductive and defective. All kinds of lists can help, from grocery lists to to-do lists.
Project managers use checklists to estimate and control projects.
Pilots use checklists to prepare for flight. Scuba divers use checklists before going into the water. Everyone uses lists for the same basic reason. We all recognize that when we are preoccupied, under pressure, or distracted, we forget things and make errors in judgment. Lists are like the rules that the Mount Everest climbers imposed before their climb.
