Decisions.

The framework

1. 01

   Learn the rungs, because you climb them in about a second.

   The ladder stands in a pool of observable data — everything a recording device in the room would have captured. From that pool you select a fraction. To the fraction you add meaning, drawn from your industry, your organisation, your history with this particular person. On the meaning you build assumptions, from the assumptions you draw conclusions, and the conclusions harden into beliefs you then act on. Written out it looks like six deliberate steps. Lived, it is instantaneous and feels exactly like perception, which is the whole problem: you never experience yourself inferring. You experience yourself noticing what is obviously there.

2. 02

   Run the camera test — separate what you saw from what you made of it.

   Take the conviction you are about to act on and split a page. On the left goes only what a camera and microphone would have recorded: the words said, the number on the sheet, the meeting missed, the date it happened. On the right goes everything else — the intent you attributed, the pattern you inferred, the label you applied. Most people find the left column runs to three lines and the right column runs to a paragraph. That ratio is not a failure of memory; it is the ladder, made visible. Act on the right column if you must, but stop calling it evidence.

3. 03

   Watch the reflexive loop — your beliefs are choosing your evidence.

   Argyris's sharpest point is not the climb; it is the loop back down. The belief sitting at the top of the ladder decides what you notice at the bottom next time, so the pool you select from has already been filtered by the conclusion you reached last month. The colleague you filed as careless now supplies a steady stream of carelessness, while their careful fortnight goes unrecorded entirely. This is why poor judgements strengthen rather than decay: the ladder feeds itself, and each day of confirmation arrives feeling like fresh evidence rather than the same old conclusion, returning in costume.

4. 04

   Argue one rung at a time, and show your own climb first.

   Two people disagreeing at the top rung will trade conclusions until one of them tires, because the disagreement was born four rungs down in what each of them noticed and what each of them made it mean. So move the conversation downward: here is the data I am working from, here is what I took it to mean, here is where that led me — what are you seeing that I am not? The order matters. Asking for someone's reasoning without first exposing your own is an interrogation, and people defend their ladders faster under cross-examination, not slower.
