Decision skill

Metacognition

Inspect how a judgment was formed, what influenced it and what would make you change it.

Learning outcome: You can review your reasoning process without confusing confidence, outcome and hindsight with decision quality.

When it matters

Notice the situation before naming the bias.

Practice the skill

Use a better reasoning move.

Decision contexts

Apply the skill to real kinds of decisions.

Evidence-reviewed lenses

Patterns worth checking, not labels for people.

Several patterns can fit the same situation. Use these lenses to ask better questions, then inspect the evidence behind each concept.

Outcome Bias

Outcome bias occurs when knowledge of a result changes how people evaluate the quality of a decision even when the information available at the time of the decision is held constant. Outcomes can still be relevant for learning, so the error is not 'never look at results'; it is using luck or hindsight as if it had been available to the original decision-maker.

Hindsight Bias

Knowing an outcome can make the outcome look more predictable in retrospect. The effect has been studied for decades and across many settings, but it does not mean that every confident explanation after an event is biased.

Confirmation Bias

Confirmation bias is an umbrella label for several ways existing beliefs or hypotheses can influence information search and interpretation. It should not be reduced to one behaviour such as reading only agreeable news, and a preference for confirming tests is not irrational in every task or environment.

Moral Luck

Resultant moral luck describes cases where judgments of blame, punishment, or moral evaluation differ because otherwise similar actions lead to different outcomes partly outside the agent's control. Outcome information does affect moral judgment in experiments, but the effect should not be reduced to 'people ignore intent.' Mental states, causal responsibility, belief justification, negligence, and the kind of moral judgment being asked about all matter. Some studies find that false or unjustified beliefs explain more of classic moral-luck asymmetries than the bad outcome itself, while still detecting an independent outcome effect.
