Before you can decide better, you have to understand the machinery doing the deciding. This module covers the two systems behind every choice, the predictable biases that quietly distort judgement, how the framing of a question changes the answer, and the crucial question of when to trust your gut and when to distrust it.

Intuition collapses under complexity. This module gives you the structured tools that scale: defining the actual decision and its criteria, weighing options with a decision matrix, putting numbers on uncertainty with expected value, and seeing the hidden cost in every choice — the option you didn't take.

Most real decisions are made without enough information, and waiting for certainty is itself a decision. This module covers thinking in probabilities instead of certainties, anchoring on base rates, stress-testing a plan with a premortem, and the single most useful sorting question in decision-making: is this reversible or not?

A good decision badly communicated fails anyway. This module covers making roles explicit so everyone knows who actually decides, leading with the reasoning rather than the verdict, the discipline of disagree-and-commit, and how transparency about trade-offs builds the trust that makes decisions stick.

Individual skill isn't enough if the environment punishes good decisions. This final module is about the conditions that let teams decide well repeatedly: the safety to dissent and be wrong, matching decision speed to decision type, and learning from outcomes without falling into the trap of judging the decision by the result.
