Cognitive Move
Hierarchical partition
Instead of one flat cut, stack two or three levels of grouping, and let each branch be split by its own rule. You then act at whichever level the decision lives on: broad strokes up top, fine distinctions only where they change something.
Cognitive Move
Hierarchy
Nest the material into levels where each item sits under exactly one parent, so a reader can collapse to a summary or drill down into detail. Best for containment and classification. Wrong whenever things legitimately belong in two places at once.
Cognitive Move
Hierarchy
Puts one thing under another, so levels stop being compared as peers and every item has exactly one parent.

Higher uncertainty × Irreversible
The one cell where you should not simply choose yet. You know too little and cannot take it back, so make the bet smaller, split it into stages, buy yourself an exit, delay, or redesign it into something recoverable.

Cognitive Move
histogram
The values themselves go along the bottom axis, and the height of each bar is how many cases fell into that slice of the range. It is not a bar chart of categories, it is a picture of a set. What you are looking for is shape: one hump or two, a long tail on one side, a gap where nothing landed. Bin width changes the shape, so pick it once.

Cognitive Move
Holdout / pilot
