every choice has a payoff you can see and a chain of consequences you can't — and the second one usually decides your life.

the move
Second-order thinking is just refusing to stop at the first result. Every action has a loud immediate effect, then quieter ones that ripple out behind it. First-order thinkers ask "what happens?" Second-order thinkers keep asking "and then what?" Sociologist Robert K. Merton named the academic version in 1936; investor Howard Marks made the "second-level thinking" framing famous. It's a mental model, not a measured law.
the first effect
You make the move and the obvious thing happens — fast, visible, satisfying. You buy the thing, the dopamine hits. You skip the workout, you get your night back. You snap at someone, you win the argument. This layer is loud and immediate, and it's the only one most people ever budget for.
