Cognitive Move

The D/S bright line

A one-question test for telling Destination problems (what outcome counts as better, and who has the right to define or revise it) apart from System problems (who or what carries the work, through which handoffs and checks), so teams stop arguing about ownership when the real gap is an unsettled definition of success.

The Goldilocks Band

Replace an exact target with 3 zones, too little, workable, too much, each with an observable boundary.

Cognitive Move

the habit as a roommate

A recurring behavior drawn as a housemate who lives in your space, takes a share of it, and leaves things where you find them later. The space is what makes this one work. The figure has to physically occupy the room in the drawing, so what it displaces is visible rather than implied, and the argument stops being about willpower.

Mental Model

The Idea Maze

Balaji Srinivasan's concept that the value of a startup isn't just the initial idea but the founder's mental map of the entire space of possible pivots, competitor responses, and market evolutions surrounding that idea

Mental Model

The tendency to maintain the status quo, stay in our comfort zone, and continue doing what we've been doing even when better options exist

The Intentional Stance

The intentional stance predicts behavior by attributing beliefs and goals under suitable rationality assumptions

Mental Model

The Law of Diminishing Returns

Diminishing marginal returns means that, beyond some point, additional units of one input add progressively less output while other relevant inputs remain fixed

Cognitive Move

The Lead–Lag Couple

Pair one weekly steerable behavior with one delayed real result, and set a date to distrust the lead if the lag doesn't move.
