Attention has a shape before it has a subject. The phenomenologist Maurice Merleau-Ponty spent years demonstrating that perception is not passive reception — it is motor-readiness: the body leans toward what it expects to encounter, and that lean pre-filters everything that arrives. Most people apply this insight to physical skill, but it runs just as deep inside a mental model. A mental model is not a neutral lens you pick up and put down — it is a posture. Once adopted, it trains your attention to arrive at situations already tilted, already scanning for the inputs it knows how to process. The model isn't applied after you see the situation; it governs what you see. The practical consequence is uncomfortable: swapping one mental model for another while keeping your existing scanning habits intact is like changing a destination without changing the direction you're already walking. Before reaching for a new framework, it's worth asking what your attention is already leaning toward — what it is pre-selecting before you've consciously started thinking.

Think of the last complex situation you had to read quickly — what did you notice first, and what would someone with a completely different professional background have noticed instead?
