--- Angus Fletcher, in conversation with Russ Roberts about his book, Primal Intelligence, EconTalk, Nov 3, 2025, 11:25
Russ Roberts: But, say a little bit about this idea of why it's worthwhile to plan, even though the plan is smashed as soon as your helicopter lands, because then most people would say, 'Well, then that was obviously a mistake. Why would you plan if it's not going to work out?'
Angus Fletcher: So, no plan survives contact with the enemy, which is why centralized planning is always a mistake. Which is why you always have to decentralize planning to the people on the ground, who are able to more rapidly adapt and evolve as the situation itself evolves.
The reason you plan is to become a better planner. So, this is a core thing that kind of goes to the book. It actually comes from Dwight Eisenhower, and Dwight Eisenhower says that basically what you do before any military operation is you make a plan for everything you can imagine happening. You think, 'What if my enemy does this? What if my enemy does this other thing? What if I have this unexpected breakthrough? What if I have this unexpected challenge?' You make plans, you make plans, you make plans, you make plans, you make plans; and then the moment the battle starts, you throw out all the plans, and you just focus on what's happening now.
And so, to your point, why do you spend time planning? Well, the purpose of planning is to develop the planner, not to develop the plan. In other words, it's to make you better able at inventing new courses of action on the fly.
