Smart Choices key terms

The idea that people make decisions with limited time, information, and mental capacity, so they settle for satisfactory options rather than searching endlessly for the best possible one.

Choosing the first option that meets an acceptable standard instead of comparing every alternative. It is a practical response to limited time and information.

A quick mental shortcut or rule of thumb that simplifies a judgment. Heuristics save effort but can produce predictable errors when the situation does not match the shortcut's assumptions.

A systematic pattern of deviation from rational judgment, shared by many people. Biases are not random mistakes; they recur in predictable situations and can be anticipated and countered.

The tendency to seek, notice, and remember information that supports what you already believe while ignoring or discounting contrary evidence. It distorts how information is gathered and weighed.

Judging how likely something is by how easily examples come to mind. Vivid or recent events feel more probable than they are, which skews risk estimates.

Letting an initial number or piece of information pull subsequent estimates toward it, even when that starting point is arbitrary or irrelevant.

The way a choice is described, including what is treated as a gain or loss, what reference point is used, and which details are included or left out. The frame shapes which option looks best.

The shift in preference that occurs when the same decision is presented in different but logically equivalent ways, such as describing an outcome as a survival rate rather than a mortality rate.

The baseline against which outcomes are judged as gains or losses. It may be the status quo, a goal, or an expectation, and moving it can reverse a preference.

The tendency for losses to feel more painful than equivalent gains feel pleasurable. It makes people take risks to avoid losses and resist giving up what they already hold.

A preference for keeping things as they are, so that doing nothing feels safer than changing course even when change would be better.

Money, time, or effort already spent that cannot be recovered. It should not influence a forward-looking choice, yet people often continue failing courses of action to justify past investment.

The value of the best alternative you give up when you choose an option. Comparing options by their opportunity cost keeps hidden sacrifices visible.

Giving up some of one desirable thing to get more of another. Recognizing trade-offs prevents the illusion that a choice can satisfy every objective at once.

A goal or outcome that a decision is meant to achieve. Clear objectives define what counts as a good choice and guide which alternatives are worth considering.

A linked sequence in which achieving one objective becomes the means to a higher-level objective. Tracing the chain reveals the fundamental aims behind a stated goal.

The deepest reason you care about a decision, stated so that asking why again adds nothing. It anchors the evaluation and keeps lower-level goals in perspective.

A specific standard used to compare alternatives against an objective, such as cost, speed, or reliability. Criteria make abstract goals measurable enough to rank options.

One of the possible courses of action under consideration. A good decision process deliberately generates options beyond the obvious ones, including combined and creative choices.

A table that lists alternatives as rows and criteria as columns, with scores in each cell. It makes comparisons visible and exposes where options differ sharply.

Assigning relative importance to criteria so that a score reflects what matters most. Weights turn a multi-criteria comparison into a single ranking while making priorities explicit.

A situation where outcomes and their likelihoods are not fully known. It differs from risk because probabilities cannot be reliably assigned, so robustness and flexibility matter more.

Exposure to possible losses where the likelihoods of outcomes can be estimated, at least roughly. Risk can be quantified, compared, and managed through mitigation or insurance.

A judgment about how likely an outcome is, often expressed as a percentage. Good estimates are calibrated, meaning events assigned a given chance occur about that often.

The average outcome if a decision were repeated many times, computed by multiplying each outcome's value by its probability and summing. It is useful for repeated bets but can mislead for one-off decisions.

How much potential loss a person or group is willing to accept in pursuit of a gain. It shapes which options are acceptable even when expected values are similar.

Testing whether a decision changes when key assumptions or estimates are varied. If the preferred option flips under small changes, the choice is fragile and needs more investigation.

Information that could show a favored belief or option to be wrong. Actively seeking it is a standard defense against confirmation bias.

The worth of gathering more data before deciding, measured by whether it could change the choice. When new information would not alter the decision, collecting it wastes time.

Anyone affected by or able to influence a decision, including those who bear its costs. Mapping stakeholders reveals whose interests and objections must be addressed.

Identifying the parties affected by a decision and assessing their interests, influence, and likely reactions. It helps anticipate resistance and design choices that can be accepted.

A pattern in cohesive groups where pressure for agreement suppresses doubts and alternatives. It produces overconfident, poorly examined decisions and is countered by dissent and outside input.

A role in which someone deliberately argues against the leading option to test its weaknesses. Formalizing the role gives dissent legitimacy and reduces groupthink.

A structured way to combine expert judgments through anonymous rounds of estimates and feedback. Anonymity reduces pressure to conform, and repeated rounds move opinions toward consensus.

A document that specifies who does what, by when, with what resources, and how progress will be tracked. It turns a chosen option into concrete, accountable action.

Imagining that a decision has already failed and working backward to explain why. This technique surfaces risks and implementation obstacles before they occur.

A structured look back at a past decision to compare outcomes with expectations and assess the process used. It separates bad luck from bad judgment and improves future choices.
