System 1 and System 2 Thinking; Pt. 4

Intuition Feels Right; That’s the Problem

Following our intuitions feels more natural and pleasant than acting against them. This is as true on the mat as anywhere else. When System 1 generates a strong pull toward a particular move, it is deeply satisfying to follow that pull. Resisting it requires System 2 effort, and System 2 is, as Kahneman notes, lazy by nature. It readily endorses intuitive beliefs and reluctantly challenges them.

This means that a coherent-feeling game plan is not the same as a correct one. If your System 1 has developed around a specific style, it will generate strong intuitive pulls in that direction, regardless of whether those pulls are strategically appropriate for the opponent in front of you. System 2 will tend to endorse those impressions because they are fluent, because they fit the internal narrative, and because questioning them is effortful.

Good jiu-jitsu requires a periodic willingness to override that comfort, to let System 2 ask whether the intuition is actually sound rather than simply accepting that it feels like it is. This is the intellectual discipline that separates grapplers who refine their game from those who merely reinforce it.

What to Do With All of This

The framework does not prescribe a single training method. It suggests a set of questions worth asking regularly.

Is this technique automated enough to free up working memory, or am I still running it on System 2 capacity that I need for something else? Am I misreading situations because my System 1 is pattern-matching on incomplete information? When I get surprised, am I letting System 2 update the model, or am I moving on before the lesson lands? Am I following a strategic intuition because it is sound, or because examining it is uncomfortable?

The central argument is not that System 1 is bad and System 2 is good. It is that the two systems work well together when each is doing the right job, and poorly when System 1 is running territory it hasn't earned, or when System 2 is too lazy to push back when it should.

Jiu-jitsu, at its best, is a System 1 worth trusting, with enough System 2 discipline to know when not to trust it.
