This study presents new evidence confirming that human personality is related to individual facial appearance. We present new findings demonstrating the statistically significant prediction of a wider set of personality features (all the Big Five personality traits) for both men and women using real-life static facial images. Even though the associations between isolated facial features and personality characteristics sought by ancient physiognomists have emerged to be weak, contradictory or even non-existent, the holistic approach to understanding the face-personality links appears to be more promising.

We investigated the accuracy of face-based personality impressions using a large set of faces (N = 1,000) and personality self-ratings (N = 2,000) across two samples and four traits (extraversion, agreeableness, neuroticism, openness). Our findings consistently suggest that people show neither accuracy nor meta-accuracy when forming face-based personality impressions. Personality impressions from faces do not reflect targets’ actual personality (i.e., we find no evidence for accuracy). We find that personality impressions from faces are not accurate.

While these judgments are prevalent, spontaneous, and impactful, they often lack accuracy. Research has shown that people can make above-chance level inferences regarding traits like extraversion, neuroticism, agreeableness, self-esteem, and even sexual orientation based solely on appearances. However, the correlations between external evaluations and self-reported personality traits remain modest, which constrains the practical applicability of these assessments. In conclusion, individuals often make rapid judgments regarding others' character, abilities, preferences, social implications, and even humanity based on facial appearances. However, the accuracy of these judgments is limited, and people tend to overestimate their ability to make such assessments.

However, direct evidence of association between facial shapes and personality is missing from the current literature. As shown in Fig. 1c, we found that the 3D facial shapes were significantly associated with personality trait A (Agreeableness; Pearson’s correlation ρ = 0.233, permutation test p < 0.001) for males. Overall, our results suggest that among the Han Chinese, a male’s personality is more apparent on his face than a female’s is on hers, and this is supported by both CPLSC and PCA methods.

Using faces with neutral expressions, it is demonstrated that personality information conveyed in faces changes the interpretation of verbal information. Moreover, it is shown that physiognomic information has a consistent effect on decisions, and creates overconfidence in judgments.

Both meta-analyses revealed significant, modest accuracy (face level, r = .14; perceiver level, r = .27) in facial trustworthiness impressions. Perceiver-level effects depended on domain, with aggressiveness and sexual unfaithfulness having stronger effects than agreeableness, criminality, financial reciprocity, and honesty. These results indicate that judgments of facial trustworthiness show a small but reliable kernel of truth, rather than being entirely physiognomic stereotypes.

These studies have found that there might be a "kernel of truth" to the validity of facial judgments of the Big Five, with above-chance agreement found especially for judgments of extraversion, and often also for agreeableness and neuroticism. In Study 1, we found that participants could consistently form impressions of the Big Five personality traits from a large set of naturalistic face photographs, such as the kind of photographs that can be viewed while browsing online. However, the accuracy of these impressions relative to targets’ self-reported personality was generally modest, consistent with the idea that face-based personality judgments contain some valid information but are far from perfectly accurate.

Our findings suggest that face-based personality impressions are not accurate, that perceivers lack insight into their (in)accuracy, and that most people overestimate their accuracy. Using larger samples of perceivers and targets than most previous studies, we found no significant associations between personality judgments based on a facial photograph and self-reported personality scores of targets. Bayesian analyses yielded strong support in favor of the null hypothesis, suggesting that, in our data, facial appearance explained virtually none of the variance in actual personality traits, despite people’s confidence in their judgments.

Recent studies suggest that facial characteristics influence perceptions of personality and may, in fact, be reliable indicators of actual personality-driven behavior. Many studies have now shown that perceptions of personality drawn from single face images, short videotapes, or very brief personal encounters align with the target’s self-reported personality. Despite this, the average effect size in the meta-analysis of accuracy in categorizing perceptually ambiguous groups was significantly larger (r = 0.26) than recent estimates of the average effect size of studies across social and personality psychology in general (r = .21).

There is increasing evidence for association between relatively neutral, static facial appearance and personality traits. After controlling for such cues, participants were able to identify Agreeableness, Neuroticism, and Physical Health from faces at above-chance accuracy. For personality traits, we found a reliable laterality bias, in that the right side of the face afforded higher accuracy than the left, and that the separate contributions of shape and texture cues varied with the traits being judged.

A growing body of research shows that independent observers commonly agree on a person’s personality traits based solely on an image of their face. In our study, prototypical high agreeableness faces were identified with higher accuracy (59.4%) compared to low agreeableness faces (42.7%). All accuracies > 50% (low extraversion, high agreeableness, and low neuroticism faces) significantly surpassed chance level, indicating more correct than incorrect classification for these faces. These findings suggest that certain prototypical facial configurations are systematically associated with perceived Big Five personality traits.

In sum, Study 1 provided evidence that subtle positive emotional cues, embedded in the structure of affectively neutral faces, may constitute a valid indicator of extraversion, at least in older adulthood. Across studies, facial appearance predicted self- and peer-reported extraversion above chance, suggesting that some personality information is available in neutral facial cues. However, the authors note that accuracy is modest and limited to certain traits and age groups.

We found the prediction of personality traits from facial features to be unsuccessful, but we discovered that some traits could be inferred from a face to a certain extent. For women we confirmed that inferences could be made about the level of Openness, Striving and Dominance from a face. The identified connections between individual personality traits and Ratings were subtle but significant and mostly in accordance with previous research. Consequently we still see the average Rating score as reliable for assessing trait evaluations from facial features, although the found correlations between personality traits and trait evaluations should be seen as only valid on a group-based level.

In this way, speaking under normal circumstances, the expression of users' emotions is more natural and ecological, and there is a close relationship between facial emotional expression and personality traits. However, we only found the linear relationship between a few face key points and two dimensions of the Big Five (Agreeableness and Openness), this result suggests that faces are related to personality but that the association is limited. Our findings indicate that facial key points contain some information about personality traits, but they cannot fully predict all dimensions of the Big Five.

Studies show that people can infer others’ level of openness, extraversion, neuroticism, agreeableness, self-esteem, religiosity, competence, and sexual orientation based on their appearance at above-chance levels. Even though significant, the correlations between others’ ratings and self-ratings on these personality traits are small to moderate (~ .14 to .27), limiting the practical usefulness of these ratings. We argue that while people can infer character traits based on facial stimuli with above-chance accuracy, these inferences are not very accurate and may instead reflect prejudice rather than true personality.

The results showed that some personality traits are more related to the tested facial features and can be predicted reliably, such as Rule-Consciousness and Vigilance, while some other personality traits may be harder to predict. The experiments results show that it is difficult to predict intelligence from either the facial features or the fingerprint feature, a finding that is in agreement with previous studies.

Studies in Japan and the United States have demonstrated that this belief can be measured reliably and invariantly across cultures and that those having stronger beliefs make more extreme trait inferences from faces. Study 1 showed that the Physiognomic Belief Scale is a cross-culturally valid and reliable measure and supports most of the predictions regarding physiognomic belief.

We present new findings demonstrating the statistically significant prediction of a wider set of personality features (all the Big Five personality traits) for both men and women using real-life static facial images. The mean absolute error (MAE) of prediction ranged between 0.89 and 1.04 standard deviations, indicating that while predictions were better than chance, they were far from precise. The between-individual proportion of variance in the predicted scores ranged from 79 to 88% for different traits, indicating a general consistency of predicted scores for different photographs of the same individual.

A variety of findings in the fields of constitutional personality theory, person perception, emotion, and orthodontic dentistry suggest there may be a relationship between personality dimensions and facial structure. Subjects with long, angular faces were found to be more responsive, assertive, and genuine than subjects with short, square faces who were more restrained, conforming, and shrewd. These results provide preliminary support for the hypothesis that certain aspects of facial structure covary with personality dimensions.

Now, here is the idea I am going to run with: the data from twin studies suggest that extraversion, agreeableness, and conscientiousness (and/or their facets) have such a strong genetic basis in part because they co-vary with highly heritable traits such as size of cheekbones, location of eyebrows, and eye shape. In fact, there is evidence to suggest that prominent cheekbones and high inner eyebrows reliably signal trustworthiness, whereas other facial features reliably signal other facets of personality. The article proposes that facial features and personality traits may be linked through shared genetic and developmental factors, although this is presented as a theoretical synthesis rather than definitive proof.

Overall, there was only evidence that extraversion related to scores on the CFMT+. No other personality traits correlated with face processing. Accurate personality judgment from faces was unrelated to trait judgment accuracy values correlated with participant face processing. These findings suggest that individual differences in face recognition ability do not substantially relate to personality traits, and that being good at face recognition does not imply being more accurate at judging personality from faces.

Result 3.1 showed that different face shapes were not associated with any particular personality traits. Conclusions: Traditional physiognomy theory which explains personality by face shapes can’t be supported by the results. Our data suggest that while people may believe that face shape reflects personality, empirical testing did not find reliable associations between face-shape categories and personality traits measured by standard questionnaires.

Traits associated with agreeableness (such as warmth, aggression, sympathy, and trustworthiness) were primarily deduced from the face, while traits linked to conscientiousness (like dependability and carelessness) were perceived from the body. This research on "first impressions" integrating faces and bodies in personality trait perception shows that different aspects of appearance contribute differentially to inferred personality traits, with the face playing a key role for social warmth-related traits.

Known as "facultative personality calibration", this is the idea that our personalities develop in a way that best suits the other genetic cards we’ve been dealt, including our size, strength, and attractiveness. Evidence supporting facultative personality calibration is growing – not only in terms of how one’s looks influence our personality traits, but even our approaches to finding romantic partners and our political beliefs. One study out of Germany’s University of Göttingen recently reported that of more than 200 men, those who were physically stronger and who had more "macho" bodies – including larger chests and biceps – also tended to be more extroverted, especially in the sense of being more assertive and physically active. This article summarizes research suggesting that aspects of physical appearance and build are correlated with certain personality dimensions.

Therefore, information from all the facial features is used and plays a significant role in judging facial traits. Globally, our results are compatible with this, showing that most of the facial features have a statistically significant effect on how an observer perceives facial traits. This suggests that perceived personality-related traits (such as trustworthiness, dominance, and attractiveness) are systematically influenced by specific facial features, even if this does not guarantee that these perceptions are accurate about the person’s actual personality.

We present new findings demonstrating the statistically significant prediction of a wider set of personality features (all the Big Five personality traits) for both men and women using real-life static facial images. Our results demonstrate that real-life photographs taken in uncontrolled conditions can be used to predict personality traits using complex computer vision algorithms.

It was predicted that participants would accurately perceive psychopathic traits and criminal propensity from facial photographs of sexual serial killers and non-criminals. This prediction was supported. It was concluded that the results were consistent with processes of over-generalisation, but that the occurrence of direct physiognomic perception could not be ruled out.

Scientists are uncovering evidence that some personality traits may be written all over our faces. In previous experiments, Perrett and Little have found that digitally altering the masculinity and femininity of a face affects how people perceive aspects of their personality, such as dominance and trustworthiness. These studies show that observers consistently infer personality characteristics from facial appearance, although the extent to which these inferences reflect actual traits rather than stereotypes remains an open question.

Physiognomy or face reading is the practice of assessing a person's character or personality from their outer appearance — especially the face. Due to its legacy of racism and junk science masquerading as criminology, scientific study or discussion of the relationship between facial features and character has become taboo. The article notes that facial characteristics influence first impressions of others, which influences our expectations and behavior, which in turn influences character, and that biological factors such as hormone levels and gene expression can affect both facial appearance and character traits. It also cites studies where facial width has been correlated with aggressive behavior and where machine learning systems have predicted political orientation and some personality traits from facial images.

Four overgeneralization hypotheses derived from an ecological approach to social perception provide an account of why facial appearance matters in impression formation. The qualities that can be accurately revealed by the facial information that conveys low fitness, age, emotion, or familiarity also tend to be perceived in people whose faces merely resemble one of these facial qualities. This review explains how facial appearance shapes social impressions, some of which have a kernel of accuracy, while many reflect overgeneralization from cues that only weakly relate to underlying traits.

Physiognomy as a practice meets the contemporary definition of pseudoscience and is regarded as such by academics because of its unsupported claims. Popular belief in the practice of physiognomy is nonetheless still widespread, and modern advances in artificial intelligence have sparked renewed interest in the field.
