Psychometric Measurement & Judgment Biases

← Back to Domain-Specific Families

Abstractions about how psychological traits and attitudes are measured — item response theory, content validity, differential item functioning, and scaling methods like Thurstone scales — alongside cognitive and judgment biases such as overconfidence, narrative bias, and outcome primacy, and stage-based behavior-change theories.

29 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Affective events theory — Explain workplace attitudes and behavior by tracing how features of the work environment generate daily events, which elicit emotions and moods that drive affective reactions alongside slower cognitive judgments.
• Cognitive-affective personality system — CAPS explains stable, person-specific if–then behavior patterns across situations through a proposed network of interacting cognitive-affective mediators.
• Computerized adaptive testing — Computer-administered assessment that updates an examinee ability estimate after each response and selects subsequent items to maximize information subject to content, exposure and stopping constraints.
• Consideration and initiating structure — Two independent leadership-behavior dimensions distinguishing relationship-oriented consideration from task-organizing initiating structure.
• Content validity — The extent to which a measure's items adequately represent every relevant facet of its intended construct or content domain.
• Culture shock — The disorientation and adaptation process experienced when familiar social cues, norms and routines no longer work in a new cultural environment.
• Demand characteristics — Cues in a research situation that let participants infer the study's purpose or expected behavior and alter their responses accordingly, creating a validity threat.
• Differential item functioning — A psychometric condition in which people from different groups with the same level of the measured trait have different probabilities of an item response.
• Expectancy-value theory — A family of motivation and choice models in which behavior depends jointly on expected success or outcome and the subjective value assigned to that outcome or task.
• Facial feedback hypothesis — The hypothesis that producing or inhibiting a facial expression can causally alter the intensity or quality of the corresponding emotional experience.
• Health action process approach — A stage-based health-behavior theory separating motivation to form an intention from volitional planning, action and maintenance processes.
• Hot hand — A proposed short-run elevation in success probability following recent successes, especially in repeated sports or skill performance.
• Item analysis — A psychometric evaluation and selection process that examines candidate questions for difficulty, discrimination, redundancy, model fit, fairness and construct coverage before assembling or revising a test.
• Item response theory — A psychometric framework modeling the probability of an item response as a function of a latent trait and item parameters.
• Item-total correlation — The correlation between one scored assessment item and a total or rest score, used to evaluate whether the item aligns with the construct measured by the scale.
• Narrative bias — A cognitive tendency to privilege coherent stories over complex, statistical, fragmented, or causally unrelated information.
• Nocebo — Worsening symptoms or adverse outcomes caused or amplified by negative expectations, conditioning and treatment context rather than the specific harmful action of an intervention.
• Outcome primacy — A learning bias in which the result of an initial experience with a task exerts disproportionate and persistent influence on later choices and probability weighting.
• Overconfidence effect — Miscalibration in which confidence, perceived performance, comparative rank, or precision systematically exceeds warranted accuracy.
• Pairwise comparison (psychology) — A psychometric elicitation method that presents two stimuli at a time and records a preference, similarity, or relative-attribute judgment for later scale estimation.
• Perceived control — A person’s belief about how much influence they can exert over outcomes, behavior, processes or surrounding conditions.
• Policy capturing — A judgment-analysis method that fits a statistical model to repeated decisions in order to estimate how a person weights available cues.
• Pollyanna principle — A positivity bias favoring pleasant information in memory, attention or judgment under specified conditions.
• Reaction formation — A psychoanalytic defense in which an unacceptable or anxiety-provoking impulse is managed by adopting and exaggerating the opposite attitude or behavior.
• Social problem-solving — The self-directed cognitive and behavioral process of identifying adaptive responses to everyday interpersonal and practical problems.
• Subjective validation — The bias of judging a vague, coincidental or unsupported statement as accurate because it feels personally meaningful or confirms existing beliefs.
• Suggestion — A psychological influence process in which presented ideas or cues guide thoughts, feelings or actions with reduced deliberate evaluation.
• Thurstone scale — An equal-appearing-interval attitude scale built by having judges locate statement favorability and selecting items with separated medians and low ambiguity.
• Transtheoretical model — An integrative behavior-change model organizing readiness into stages and relating progression to change processes, decisional balance and self-efficacy.
