Where this record's text came from. 2026-08-21, 2026-08-26 and 2026-08-28 schema-0.3 passes: every quote verified as an exact substring of the staged text and anchored at merge time; concept terms verified present; every edge endpoint an existing node.
This record’s own method is systematic-review, and the tags below follow from that. A review’s findings, quantities and statistics are things stated IN this paper, and some of them report results obtained elsewhere. No tag on this page names a different author. Measured across every review in this corpus, 81% of a review’s tags carry no citation at all — most of them are the review speaking. The corpus does not adjudicate the rest: read an unmarked tag as a claim this paper makes, not necessarily one it made first.

phenomenona measurement routinely given the name of the construct it is taken to reveal, so that the name carries an inference the data do not support— “Fourth, published research on emotional expressions and emotion perception often confounds the measurements made in an experiment with the interpretation of the data, referring without sufficient justification to facial movements as “emotional displays,” “emotional expressions” or even “facial expressions,” rather than “facial…

method — evidence— “Our review is the most comprehensive and systematic to date, encompassing studies of healthy adults across cultures, newborns and young children, as well as people who are congenitally blind, and confirms that specific emotion categories -- anger, disgust, fear, happiness, sadness, and surprise – are each expressed with a particular…
object of study — evidence— “When you see someone smile and infer that the person is happy, you are making what is known as a reverse inference: you are assuming that the smile reveals something about the person’s emotional state that you cannot access directly (see Figure 3).”
research question — evidence— “Four criteria must be met to justify a reverse inference that a particular facial configuration expresses and therefore reveals a specific emotional state: reliability, specificity, generalizability and validity (explained in Table 2 and Figure 3). These criteria are commonly encountered in the field of psychological measurement and over the…

These criteria are commonly encountered in the field of psychological measurement and over the…transfers[0]
transferfrom cognitive neuroscience: reverse inference, and the conditional probability that formalises it, carried from neuroimaging methodology into the reading of faces— “When you see someone smile and infer that the person is happy, you are making what is known as a reverse inference: you are assuming that the smile reveals something about the person’s emotional state that you cannot access directly (see Figure 3).”transfers[1]
mechanismresponse-set constraint manufacturing agreement offering a participant six emotion words and one face forces a choice among them, so agreement measures how the options were built rather than what the face conveys; remove the array and let people supply their own word and the rates fall— “Choice-from-array tasks severely limit the possibility of observing evidence that can disconfirm the common view of emotional expressions, however, because they restrict participants’ options for inferring the psychological meaning of facial configurations by offering them a limited set of emotion labels.”mechanisms[0]
mechanismvalence perception passing as emotion perception where happiness is the only pleasant category in the array, every distractor differs from the target in valence, so a participant can score perfectly by discriminating pleasant from unpleasant without perceiving any emotion category at all— “This is particularly true for studies that include only one pleasant emotion category, i.e., happiness, where all foils differ from the target in valence, and therefore the robust reliability and specificity for inferring happiness from smiling in these studies may be the result of participants engaging in valence perception rather than…mechanisms[1]
mechanismnaming carrying the inference calling a measured facial movement an 'emotional display' imports the conclusion into the description, so a later reader inherits an inference nobody tested; the same happens with 'recognizing' rather than 'inferring' and 'accuracy' rather than 'agreement'— “Fourth, published research on emotional expressions and emotion perception often confounds the measurements made in an experiment with the interpretation of the data, referring without sufficient justification to facial movements as “emotional displays,” “emotional expressions” or even “facial expressions,” rather than “facial…mechanisms[2]
mechanismabove-chance publication threshold a result reliable enough to publish can still be low in absolute terms, so a literature of individually valid findings accumulates into a consensus that no single finding supports— “First, statistical standards are commonly adopted that don’t translate well for applying emotion research to other domains, applied or scientific. Showing that people frown when sad or scowl when angry with greater statistical reliability than would be expected by chance may be a scientific finding that warrants publication in a peer-reviewed…mechanisms[3]
critiques the common view that each of six emotion categories is reliably and specifically expressed by, and recognisable from, its own configuration of facial movements— “People do express instances of anger, disgust, fear, happiness, sadness and surprise with the hypothesized facial configurations presented in Figure 4 at above chance levels, suggesting that those facial configurations sometimes serve as expressions of emotion as proposed. However, the reliability of this finding is weak, and there is…claim_relations[0]
critiques automated emotion-recognition technology that infers emotional states from facial movements alone— “Technology companies, for example, are spending millions of research dollars to build devices to read emotions from faces, erroneously taking the common view as the one that is scientifically best supported. A more accurate description, however, is that their technology detects facial movements, not emotional expressions.”claim_relations[1]
qualifies choice-from-array emotion-perception findings, which supply the strongest support for the common view and cannot produce disconfirming evidence— “Choice-from-array tasks severely limit the possibility of observing evidence that can disconfirm the common view of emotional expressions, however, because they restrict participants’ options for inferring the psychological meaning of facial configurations by offering them a limited set of emotion labels.”claim_relations[2]
reinterprets the canonical six facial configurations - as Western stereotypes rather than as prototypes or universal displays— “Instead, the facial configurations in Figure 4 are best thought of as Western gestures, symbols or stereotypes that fail to capture the rich variety with which people spontaneously move their faces to express emotions in everyday life. A stereotype is not a prototype. The distinction is an important one, because a prototype is the most…claim_relations[3]
sense"emotional expression" - AS LICENSED: a facial configuration that reliably and specifically communicates an emotional state. The paper's glossary adds that many so-called emotional expressions are errors of reverse inference— “Emotional expression a facial configuration, bodily movement, or vocal expression that reliability and specifically communicates an emotional state. Many so-called emotional expressions are in fact errors of reverse inference on the part of perceivers (e.g., an actor crying when not sad).”senses[0]
sense"emotional expression" - AS USED IN THE LITERATURE: any facial configuration labelled with an emotion category, applied without checking reliability, specificity, generalizability or validity— “Fourth, published research on emotional expressions and emotion perception often confounds the measurements made in an experiment with the interpretation of the data, referring without sufficient justification to facial movements as “emotional displays,” “emotional expressions” or even “facial expressions,” rather than “facial…senses[1]
sense"accuracy" - AS DEFINED: correspondence to an intended performance that must be perceiver-independent and not subject to the whims of the experimenter— “Accuracy Extent to which a participant’s performance corresponds to the intended performance on an experimental task. Critically, this requires proper experimental task design, so that the intended correct performance is perceiver-independent, and not subject to the whims of the experimenter.”senses[2]
sense"accuracy" - AS IT SHOULD BE RENAMED in this literature: agreement or consensus, because what these studies measure is whether people label a face the same way, not whether the label is correct— “Fourth, published research on emotional expressions and emotion perception often confounds the measurements made in an experiment with the interpretation of the data, referring without sufficient justification to facial movements as “emotional displays,” “emotional expressions” or even “facial expressions,” rather than “facial…senses[3]
sense'common view' / 'classical view' - THE FRAMEWORK THIS PAPER IS AGAINST HAS TWO NAMES, AND THE SECOND APPEARS EXACTLY ONCE: 'a set of beliefs were refer to as the common view (also called the classical view)'. A definitions row already glosses 'Common view'; what was missing is that the literature this paper argues with calls it something else. A reader searching the corpus for 'classical view' - which is what the opposing literature calls itself - would not have reached this record.— “A simple Google search using the phrase “emotional facial expressions” [see Box 1, in supplementary on-line materials (SOM)] reveals the ubiquity with which, at least in certain parts of the world, people believe that certain emotion categories are reliably signaled or revealed by certain facial muscle movement configurations – a set of…senses[4]
senseFacial movement - an objective, perceiver-independent configuration description that makes no emotional inference— “Facial movement A facial configuration that is objectively described in a perceiver-independent way. This description is agnostic about whether the movement expresses an emotion and does not use reverse inference. FACS coding is an example”senses[5]
senseFacial expression - a perceiver-dependent inference that a facial configuration expresses an internal state— “Facial expression A facial configuration that someone infers is expressing an internal state. Facial expressions of emotion are configurations that perceivers reverse infer to have been caused by an internal emotion state; they are thus perceiver-dependent”senses[6]
sensePerceiver-dependent - interpretation depends on human judgment and may be consistent without being accurate or valid— “Perceiver-dependent Interpretation of an observation that depends on human judgment. Perceiver dependency can produce conclusions that are consistent across people but not accurate or valid. Perceiver-independent An observation that does not depend on human judgment.

Although some philosophers argue that all observations require some human…senses[8]
senseForward inference - inferring an effect from a known cause, such as frowning conditional on anger— “Forward inference Inferring an effect from knowing its cause. An example would be the conditional probability of observing a frown given we know somebody is angry”senses[9]
sensePercent agreement - inter-rater consistency, explicitly not percent accuracy— “Percent agreement A measure of agreement between raters; high agreement produces high inter-subject consistency. Percent agreement is not the same as percent accuracy, since the former is more perceiver-dependent than the latter”senses[10]
sensePercent accuracy - not interchangeable with agreement because agreement is more perceiver-dependent— “Percent agreement A measure of agreement between raters; high agreement produces high inter-subject consistency. Percent agreement is not the same as percent accuracy, since the former is more perceiver-dependent than the latter”senses[11]
senseRecognition - acknowledging an independently confirmed existent, contrasted with interpretive perception— “Recognition Acknowledging something’s existence (which is confirmed to exist by perceiver-independent means). Contrast with perception (which involves inference and interpretation)”senses[12]
sensePerception - inference and interpretation rather than independently confirmed recognition— “Recognition Acknowledging something’s existence (which is confirmed to exist by perceiver-independent means). Contrast with perception (which involves inference and interpretation)”senses[13]

When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.
