Kahneman's distinction between System 1 and System 2 thinking is widely known — but the more useful insight is buried deeper in 'Thinking, Fast and Slow': System 2 doesn't correct System 1, it mostly *rationalizes* it after the fact. This means your carefully constructed mental models are often not tools for deciding, but tools for explaining decisions you've already made intuitively. The practical implication: before you reach for a framework, ask whether you're genuinely thinking or merely narrating. Inserting a brief pause — even 90 seconds — before articulating your reasoning can shift you from post-hoc storytelling to actual analysis.

Think of a recent decision where you felt confident in your reasoning — what would it look like if the reasoning came *after* the conclusion, not before it?
