Definition
A cost-benefit matrix forces quantity on a habit fork: for each horizon (short / medium / long) and each stake (self, loved ones, projects, vision), name several real prices of staying the same — then mirror with benefits of the new move.
Origin
Expected-utility models assume rational weighting of outcomes; Kahneman and Tversky’s prospect theory shows loss aversion and the certainty effect — sure losses feel heavier than equivalent probable ones, and isolated frames change preference. A written matrix makes implicit prices visible in ink before the nervous system negotiates.
Mechanism
Theory convinces but resistance wins when felt price stays abstract. Three examples per cell (~100 prices) makes the status quo expensive on paper — often enough to shift behaviour without new motivation slogans. Kahneman and Tversky’s value function is steeper for losses than gains; naming losses across horizons exploits that asymmetry deliberately. The matrix works best when stakes are named first — otherwise advantages float without a real fork.
Applications
Before reinstating a stalled habit: matrix the costs of not preparing — then schedule one block to run the exercise before defaulting back to status quo.
