Mental checklists to improve thinking. Berkshire Hathaway vice-chairman Charlie Munger uses a mental checklist of biases and cognitive flaws that he reviews before making any big decision to ensure he’s thinking clearly about it. He’ll go down the list and ask himself if any of these biases are clouding his thinking and what he can do to mitigate it. Ever since I’ve learned about that, I’ve tried using something similar in my life. Crafting this list is still a work in progress for me, but here’s what I have so far:
Checklists are an effective way to get things accomplished but they can also create problems. Your success depends on the length of the checklist and your personality. Lists might help one person feel more organized, while others will feel overwhelmed or frustrated. Some people enjoy the tangible aspects of creating a list, while others ignore the list once it is created and focus on their thoughts instead. The key to effectively using a checklist is creating a list method that works for you.
Lastly, the checklist involves a Time Out: this requires that everything stops and no one interrupts. In an emergency, or under extreme time pressure, it is difficult to get everyone on the team to stop what they are doing and attend completely. The loss of team discussion under time pressure has been described by some centres implementing the Safe Surgery checklist.6 ,13 These are the times when mistakes are most likely to occur, yet paradoxically also when the Time Out portion of the checklist (the briefing to support complex work) is least likely to be performed as intended.
