Decision Criteria: Evaluation
Decision criteria are the dimensions used to compare options. Making them explicit reduces arbitrary choice and reveals when people disagree about goals rather than facts.
Essential questions
Questions this chapter should let you answer.
- What exact claim, question, or decision is Decision Criteria being used to evaluate?
- Which evidence, premises, assumptions, or probability relationships matter most to a defensible conclusion about Decision Criteria?
- What alternative explanation, counterexample, bias, or uncertainty could change the conclusion?
- What new evidence should cause a rational update, and how large should that update be?
Before you begin
Useful prior knowledge.
- Distinguish a claim from the evidence offered in support of it.
- Recognize that conclusions can be more or less certain.
- Ask what alternative explanation could fit the same evidence.
- Know the basic purpose of the Research & Decision-Making topic area and how this lesson fits inside it.

Full lesson
Build a mental model you can actually use.
Each chapter is divided according to the concept itself. Simpler ideas stay compact, while difficult topics expand into additional sections for mechanisms, evidence, calculations, examples, limitations, and connections when those are needed.
Judge the quality of evidence using the methods appropriate to Decision Criteria, rather than treating all citations, examples, or statistics as equally strong.
Evaluating the evidence for Decision Criteria
Measurements, forecasts, expert judgment, stakeholder priorities, and sensitivity analysis support criterion scores.
Options are evaluated consistently against criteria, with thresholds for must-have constraints and trade-offs among desirable attributes.
Criteria can include cost, safety, effectiveness, time, fairness, reliability, reversibility, environmental impact, or strategic fit, often with different weights.
Evidence for Decision Criteria has to be judged by how it was produced. Identify the unit of observation, comparison or baseline, measurement method, timing, and source of uncertainty that apply here. Then ask whether the evidence bears on the stated claim or only on a related question. Stronger data cannot repair a mismatch between evidence and claim.
Stress-test Decision Criteria by asking what else could produce the same observation or what case would invalidate the reasoning.
Counterexamples and rival explanations
Scores and weights still encode judgments and uncertainty; they make assumptions visible rather than eliminating them.
Measurements, forecasts, expert judgment, stakeholder priorities, and sensitivity analysis support criterion scores.
Choosing a vehicle might weight total cost, reliability, cargo space, fuel use, and safety differently depending on the user's actual needs.
A serious evaluation of Decision Criteria includes an adversarial test. Treat the most plausible rival explanation or counterexample as a competing model, not as an afterthought. Specify what each model predicts and identify an observation that would favor one over the other. If no possible evidence could separate them, the original conclusion is too strong.
Match the strength of a conclusion about Decision Criteria to the amount and quality of evidence actually available.
Uncertainty, base rates, and confidence

Criteria-based decisions improve hiring, procurement, engineering, policy, investing, and personal choices.

Confidence in a conclusion about Decision Criteria should track both evidence quality and unresolved uncertainty. Distinguish sampling or measurement uncertainty from uncertainty about assumptions, model structure, causal direction, or source reliability. A narrow numerical interval does not eliminate structural uncertainty, and cautious wording should reflect whichever uncertainty dominates.
Trace measurement, sampling, comparison, calculation, source provenance, or experimental design when those features matter to Decision Criteria.
Method check: how the evidence was produced
Options are evaluated consistently against criteria, with thresholds for must-have constraints and trade-offs among desirable attributes.

Criteria-based decisions improve hiring, procurement, engineering, policy, investing, and personal choices.
Auditing the method behind Decision Criteria means reconstructing the path from raw observation to reported conclusion. Record what was measured, omitted, transformed, compared, or assumed. Check whether the chosen method could systematically favor one result. Repeating a flawed method can improve precision while preserving the same bias, so replication and validity answer different questions.

What this model is teaching
Evaluating the evidence for Decision Criteria: understand the mechanism, then test whether the conclusion still holds.

Worked example: Choosing a vehicle might weight total cost, reliability, cargo space, fuel use, and safety differently depending on the user's actual needs. Why this matters for learning: Criteria-based decisions improve hiring, procurement, engineering, policy, investing, and personal choices. Check your understanding: Which feature of the evidence in the worked example most affects confidence in the conclusion, and why?
Criteria-based decisions improve hiring, procurement, engineering, policy, investing, and personal choices.
With a small change, hold everything else constant and identify the first thing that should move. This reveals the direction of the relationship. Connect the visible model to the mechanism, the evidence needed to support it, and the limits of the conclusion.

Change one input or assumption and compare the result. Then explain your answer using the vocabulary from Evaluating the evidence for Decision Criteria, not just a memorized definition.
