Coaching practices for System 1 vs System 2
Describe almost anything you are working through and IX Coach finds the practices whose real-world fit is closest. For System 1 vs System 2, these are the strongest matches in the current practice library.
Does this sound like the set of challenges you might be facing?
- An answer pops into my head instantly and feels so obviously right that I just go with it, and only later do I realize I never actually thought it through
- I rush the big, costly decisions the same way I rush picking lunch
- There are things I’m sure are true mostly because I’ve heard them a hundred times and they go down so smooth and familiar
- I keep promising this project will take a few weeks and it always blows way past that, and even now I’m certain this time will be different because of all the specific reasons it’s special
- I came to a snap conclusion about this and it felt totally obvious, but now I’m not sure I actually answered the hard question in front of me versus some easier version of it my brain quietly swapped in.
Practices that may help
- Thinking, Fast and Slow, Made Usable
Daniel Kahneman describes two modes of thought: System 1 is fast, automatic, and intuitive; System 2 is slow, effortful, and deliberate. Better decisions usually come from noticing when a problem deserves System 2 and deliberately slowing down — though some popular claims from the book (notably certain priming studies) failed to replicate. - Notice which system is driving
Before deciding, ask whether this is a System 1 (snap) or System 2 (effortful) problem.
Thinking, Fast and Slow, Made Usable - Slow down for high-stakes, irreversible decisions
Match deliberation to the cost of being wrong: spend System 2 where reversal is hard.
Thinking, Fast and Slow, Made Usable - Distrust easy fluency
Treat "this feels obviously right" as a flag to check, not a signal to proceed.
Thinking, Fast and Slow, Made Usable - Take the outside view (base rates)
Estimate using the track record of similar cases, not the vivid details of your own.
Thinking, Fast and Slow, Made Usable - Name the question your brain is actually answering
When you reach a quick judgment, ask: "What question did I actually just answer?"
Attribute Substitution: When Your Brain Answers a Different Question - Consider the opposite
Actively argue the case against your first conclusion before accepting it.
Thinking, Fast and Slow, Made Usable - Track the relationships between parts
Notice how parts trigger, protect, and sometimes war with each other — the system’s dynamics are as important as its members.
IFS Parts Mapping, Made Practical - Attribute Substitution: When Your Brain Answers a Different Question
Attribute substitution is Daniel Kahneman’s explanation for how heuristics work: when a question is hard to answer directly, System 1 automatically substitutes a related but easier question and answers that instead. The substitution is usually invisible, so the answer feels like a response to the original hard question when it isn’t. Recognizing the substitution is the only way to correct it. - The Two-Process Model of Sleep
Alexander Borbély’s two-process model describes sleep as the interaction of two independent systems: Process S (homeostatic sleep pressure, which builds throughout waking hours like a battery draining) and Process C (the circadian clock, which gates sleep propensity in a 24-hour rhythm). Good sleep requires both processes to align — sleep pressure high and the clock in its nighttime phase simultaneously. The model is well established in sleep science.
