Disputed Statements

Claims this atlas currently marks as unsettled or as tested and found false. A debated fact is one scholars hold competing positions on; a debunked one has been checked against the record and found not to hold. Both are kept in view rather than quietly smoothed over, with the reasoning that put each one where it stands.

Facilitated Communication Studies, Key FindingControlled studies, including blind conditions in which the facilitator and the person being facilitated were shown different pictures or questions, repeatedly found that typed messages matched what the facilitator, not the person being facilitated, could see or know; by 2005 more than fifty controlled studies had reached this conclusion, the mechanism identified as an unconscious ideomotor effect akin to a Ouija board, and the American Psychological Association stated in 1994 that there was no scientifically demonstrated support for the technique's efficacy.

Comparative neuroscience considers the model outdated: the brain structures MacLean treated as unique to each evolutionary stage are now known to appear across many vertebrate groups, including reptiles, which show cognitive abilities the model did not predict; the article states the hypothesis is now regarded as a myth, largely abandoned by comparative neuroscientists around the turn of the twenty-first century.

Community Psychology, Key DebateWhether empowerment, the field's own central organizing concept, is coherent enough to guide research and practice. Riger (1993) argued empowerment is built on a masculine, individualistic model of agency that sits awkwardly with community psychology's own emphasis on collective, relational well-being, while Guy Holmes criticized it as a vague concept that, following Wolf Wolfensberger, carries more rhetorical appeal than analytic precision.

No single founding event or year exists; the theory developed across decades through several contributors. 1923 marks Piaget's earliest major constructivist-relevant publication (The Language and Thought of the Child); Vygotsky's own sociocultural extension continued until his death in 1934; Bruner's discovery-learning and scaffolding extension of the theory followed in the 1960s.

Currently States Whether a proposed evolutionary explanation for a psychological trait can actually be tested, given how little is directly known about the ancestral environments in which the trait supposedly evolved.

Critics collected in the article's Reception and Criticism section raise testability concerns, doubts about a strictly modular brain, uncertainty about ancestral environments, and the importance of non-genetic and non-adaptive factors; the field's defenders dispute each in turn, and the disagreement is not resolved.

Currently States How strong the observation-changes-behavior effect actually was in the original data is itself contested.

The term 'Hawthorne effect' was not coined until 1953, by John R. P. French, two decades after the original studies. A 2011 re-analysis of the original illumination-experiment data by economists Steven Levitt and John List found only slight evidence for the effect over the long run, far weaker than the effect is classically portrayed as being, and the psychologist Richard Nisbett has called the whole phenomenon 'a glorified anecdote.'

Implicit Association Test Studies, Key FindingIndividual IAT scores show only middling test-retest reliability, around 0.60, and a meta-analysis by Oswald and colleagues found implicit measures were only weakly predictive of discriminatory behavior and no better than explicit self-report measures at predicting it, while other researchers maintain the test still captures a real, if imperfectly measured, automatic association.

I-O psychology has been criticized, particularly for its mid-twentieth-century record, as being responsive mainly to the concerns of management rather than workers; the industrial psychologist Arthur Kornhauser was noted as largely alone among his contemporaries in focusing on protecting workers rather than raising their productivity.

James-Lange Theory of Emotion, Core ClaimA stimulus produces a physiological (bodily) response first, and the perception of that physiological response is the emotion itself, rather than the emotion causing the physiological response.

James-Lange Theory of Emotion, Theories and Concepts

Standing

Concerns Core Claim

Currently States A stimulus produces a physiological (bodily) response first, and the perception of that physiological response is the emotion itself, rather than the emotion causing the physiological response.

Walter Cannon's 1920s critique argued that visceral (internal organ) responses are too slow and too physiologically similar across different emotions, and even across some non-emotional states such as fever, to be what generates the specific felt quality of an emotion. A 2017 re-reading by Lisa Feldman Barrett argues Cannon and Dewey misread James: James claimed each particular instance of an emotion has its own distinct bodily state, not that whole emotion categories do, which she argues survives Cannon's objection.

Judgment Under Uncertainty: Heuristics and Biases, Key FindingTversky and Kahneman identified three heuristics underlying judgment under uncertainty: representativeness, judging probability by how closely something resembles a prototype or stereotype; availability, judging frequency or probability by how easily examples come to mind; and anchoring and adjustment, estimating an unknown quantity by starting from an initial value and adjusting insufficiently away from it. Each heuristic is usually economical and effective but can produce large, systematic biases in specific, predictable circumstances.

Each heuristic is usually economical and effective but can produce large, systematic biases in specific, predictable circumstances.

That people rely on representativeness, availability and anchoring when judging under uncertainty, and that this reliance produces systematic, predictable deviations from formal probability in specific circumstances, is not itself disputed. What is genuinely contested, most prominently by Gerd Gigerenzer's ecological-rationality program, is whether those deviations are correctly described as biases against a single normative standard of rationality, or as heuristics that are well adapted to real-world information environments; see the dissent recorded on this fact.

Milgram's Obedience Experiments, Key FindingA later "engaged followership" reinterpretation by Alex Haslam and Stephen Reicher argues participants were not simply submitting to authority but were actively identifying with the experimenter's stated scientific goals, obeying most when the prod framed continuation as necessary for science rather than as a bare command.

This reframes what Milgram's own "obedience" account is taken to show without denying the extreme distress participants displayed. A separate, well-documented line of ethical criticism (raised at the time by Diana Baumrind and later by scholars including Gina Perry) concerns the deception used and the adequacy of debriefing; this atlas records both lines of critique as attributed scholarly positions.

Person-Situation Debate, Core ClaimWhether personality traits or situational factors better predict and explain a person's behavior.

Person-Situation Debate, Theories and Concepts

Standing

Concerns Core Claim

Currently States Whether personality traits or situational factors better predict and explain a person's behavior.

Situationists (following Mischel) held that personality-behavior correlations rarely exceed roughly .30 to .40 and that situational variables predict specific behavior better than broad traits; trait psychologists responded that the low correlations were misread, that laboratory settings understate how much personality matters in real-world behavior, and that some behaviors are simply more cross-situationally consistent than others. Most personality researchers today hold an integrated view, associated with William Fleeson and Erik Noftle, in which a person maintains an average ('anchor') trait level while varying around it by situation, which is offered as an explanation of both the consistency and the variability the debate was about, without being universally accepted as closing the question.
