Observer judgmental accuracy of personality: Benefits related to being a good (normative) judge

The current study tested the hypothesis that accuracy of personality judgment would be positively related to beneficial life outcomes. 189 participants observed targets across 5 dyadic interactions and made judgments of the 10 targets on the Big Five traits. Self and acquaintance ratings were used as the accuracy criteria. Normative accuracy for all traits was related to agreeableness, and normative accuracy for some traits was positively related to interpersonal control, interpersonal support, positive affect, and life satisfaction. Distinctive accuracy was not related to beneficial outcomes. These results imply that normative accuracy based on observation is associated with beneficial outcomes, whereas distinctive accuracy is not.     

Studying Stereotype Accuracy from an Integrative Social‐Personality Perspective

This article proposes an integrative framework for understanding the accuracy and inaccuracy of stereotypes. Specifically, we highlight research issues and traditions from social and personality psychology that do not often intersect, but which can be mutually informative. Within this framework, the social psychologist's interest in the accuracy of group stereotypes is conceptually much like a personality psychologist's interest in the accuracy with which perceivers can identify types of individuals, for example extraverts. Both fields make use, implicitly or explicitly, of personal attributes and behaviors (cues) in assessing accuracy of beliefs about group or individual traits. By using Brunswik's lens model perspective in combination with concepts from signal detection theory, judgments of stereotypes can be discovered to be accurate or inaccurate depending on how perceivers judge or use the cues. In drawing on research traditions and theoretical frameworks from both social and personality psychology, researchers can go beyond an all‐or‐nothing stance regarding stereotype accuracy to achieve a more nuanced understanding of when, how, and to what extent stereotypes are accurate.     

A closer look at the ability to predict psychotherapeutic outcome

On the basis of previous findings on the varying ability clinically to predict the outcomes of psychotherapy, this study is focussed on the judgmental processes of good and not-so-good judges. To chart the mechanisms of predictive accuracy, the relations between the ratings of each judge and the criteria have been modelled in terms of structural equations. Further, the predictions of one good and one not-so-good judge have been analysed by multiple regression, with aspects of patient information as independent variables. The analyses suggest that, compared to the not-so-good judge, the good judge utilises more information and has more adequate ideas about its validity but not about its internal correlational structure. While not neglecting secondary process thinking, the good judge still leaves room for intuitive, non formalised judgment and also utilises available information in a more discriminating, or radical, manner. The not-so-good judge appears as an overly conscious and cautious person, neglecting much valid information, not discriminating among the variables, and using negatively valid information positively.     

The Effect of Information Quantity on Distinctive Accuracy and Normativity of Personality Trait Judgments

Information quantity is an important moderator of personality judgment accuracy. Some evidence suggests that the amount of available information is positively related to accuracy. The current study utilized the social accuracy model to investigate the effects of differences in thin slices of information quantity on the distinctive accuracy and normativity of personality trait judgments. It was hypothesized that distinctive accuracy and normativity would increase as information quantity increased. Participants were 431 individuals who participated in an online study that varied the length of stimulus target observations (30 seconds, 1 minute, 3 minutes, and 5 minutes), after which judges rated targets using other‐report measures of the Big Five personality traits. For all traits combined, significant levels of accuracy were found for all observation lengths, but distinctive accuracy and normativity did not increase as video length increased. Findings varied for individual traits. For distinctive accuracy, there was a linear increase with information quantity for Extraversion and a non‐linear relationship for Conscientiousness, while there was a linear decrease for Openness. For normativity, there was a linear increase with information quantity for Agreeableness and a non‐linear relationship for Conscientiousness. There are important differences in how observation length affects distinctive accuracy and normativity for different personality traits. © 2019 European Association of Personality Psychology     

What is beautiful is good and more accurately understood. Physical attractiveness and accuracy in first impressions of personality

Beautiful people are seen more positively than others, but are they also seen more accurately? In a round-robin design in which previously unacquainted individuals met for 3 min, results were consistent with the "beautiful is good" stereotype: More physically attractive individuals were viewed with greater normative accuracy; that is, they were viewed more in line with the highly desirable normative profile. Notably, more physically attractive targets were viewed more in line with their unique self-reported personality traits, that is, with greater distinctive accuracy. Further analyses revealed that both positivity and accuracy were to some extent in the eye of the beholder: Perceivers' idiosyncratic impressions of a target's attractiveness were also positively related to the positivity and accuracy of impressions. Overall, people do judge a book by its cover, but a beautiful cover prompts a closer reading, leading more physically attractive people to be seen both more positively and more accurately.     

Interpersonal orientation and the accuracy of personality judgments

Are those who are more invested in developing and maintaining interpersonal relationships able to provide more accurate judgments of others' personality characteristics? Previous research has produced mixed findings. In the present study, a conceptual framework was presented and methods were used that overcome many of the problems encountered in past research on judgmental accuracy. On four occasions, 102 judges watched a 12‐min videotaped dyadic interaction and described the personality of a designated target person. Judges' personality characteristics were described by self, parents, and friends. Results revealed that psychological communion was positively associated with judges' accuracy in rating targets' personality characteristics. In addition, whereas women were more communal and provided more accurate judgments than men, the relationship between communion and accuracy held after controlling for the effect of gender. Finally, preliminary findings suggested that interpersonally oriented individuals may sometimes draw on information about themselves and about stereotypical others to facilitate accurate judgments of others.     

Handshaking, gender, personality, and first impressions

Although people's handshakes are thought to reflect their personality and influence our first impressions of them, these relations have seldom been formally investigated. One hundred twelve participants had their hand shaken twice by 4 trained coders (2 men and 2 women) and completed 4 personality measures. The participants' handshakes were stable and consistent across time and coders. There were also gender differences on most of the handshaking characteristics. A firm handshake was related positively to extraversion and emotional expressiveness and negatively to shyness and neuroticism; it was also positively related to openness to experience, but only for women. Finally, handshake characteristics were related to the impressions of the participants formed by the coders. These results demonstrate that personality traits, assessed through self-report, can predict specific behaviors assessed by trained observers. The pattern of relations among openness, gender, handshaking, and first impressions suggests that a firm handshake may be an effective form of self-promotion for women.     

An experimental examination of the “good judge”

Many personality traits have been proposed to predict a person’s ability to judge another. The predictive abilities found for these traits have been inconsistent. Funder and others (e.g., [Gilbert, 1989] and [Trope, 1986]) suggested that social knowledge, motivation to read others, and the ability to multitask are essential components of accurate judgment. In this study, we manipulated participants to be high or low in each of these characteristics and examined the impact of these manipulations on IPT-15 performance. As predicted, participants manipulated to be high in social knowledge, motivation to read others, and multitasking showed superior performance on the IPT-15 compared to participants in the corresponding low conditions. These results support Funder’s “good judge” construct as a predictor of judgmental accuracy.     

Relational Self-Construal and its Relationship to Academic Citizenship Behavior

Despite the abundance of research on personality traits and citizenship behavior, no study has examined the role of relational self-construal, which is a self-definition based on one’s close relationships. We hypothesized that relational self-construal would be positively related to academic citizenship behaviors, and that this association would remain significant while controlling for sex and agreeableness. In the study, 2,222 college undergraduates completed a self-report questionnaire measuring their relational self-construal, sex, personality, and academic citizenship attitudes. The results also confirmed the hypothesis that relational self-construal is positively related to some academic citizenship behaviors while controlling for sex and agreeableness. Specifically, relational self-construal was associated with consideration and civic virtue, but not with other citizenship behaviors.     

Information quantity and quality affect the realistic accuracy of personality judgment

Triads of unacquainted college students interacted in 1 of 5 experimental conditions that manipulated information quantity (amount of information) and information quality (relevance of information to personality), and they then made judgments of each others' personalities. To determine accuracy, the authors compared the ratings of each judge to a broad-based accuracy criterion composed of personality ratings from 3 types of knowledgeable informants (the self, real-life acquaintances, and clinician-interviewers). Results supported the hypothesis that information quantity and quality would be positively related to objective knowledge about the targets and realistic accuracy. Interjudge consensus and self-other agreement followed a similar pattern. These findings are consistent with expectations based on models of the process of accurate judgment (D. C. Funder, 1995, 1999) and consensus (D. A. Kenny, 1994).     

On the relative importance of linear model and human judge(s) in combined forecasting

When and to what extent should forecasts rely on linear model or human judgment? The judgmental forecasting literature suggests that aggregating model and judge using a simple 50:50 split tends to outperform the two inputs alone. However, current research disregards the important role that the structure of the task, judges’ level of expertise, and the number of individuals providing a forecasting judgment may play. Ninety-two music industry professionals and 88 postgraduate students were recruited in a field experiment to predict chart entry positions of pop music singles in the UK and Germany. The results of a lens model analysis show how task structure and domain-specific expertise moderate the relative importance of model and judge. The study also delineates an upper boundary to which aggregating multiple judgments in model-expert combinations adds predictive accuracy. It is suggested that ignoring the characteristics of task and/or judge may lead to suboptimal forecasting performance.     

Personality, job level, job stressors, and their interaction as predictors of coping behavior

Hypotheses concerning the relationships among job stressors, job level, personality, and coping responses were investigated in a sample of 305 electrical contracting employees. Coping behaviors were measured with questionnaire items based on interviews conducted with a sample of the subjects. Neuroticism (N) and Extraversion (E) were the personality variables most strongly related to coping behavior. Overall, more coping variance was explained by personality than by job stressors; however, when the effects of job level and job stressors were combined, they explained more variance in complaining/quitting and seeking social support than did the personality variables. Both work situation and personality seem to be important variables in the choice of coping behaviors. There was no evidence of interactions among personality, stressors, and job level in explaining coping behavior.     

Pure feedback effects in absolute identification

To reveal the pure effects of trial-by-trial feedback on judgmental accuracy and sequential dependencies independent of global anchoring effects and other influences, we presented subjects with sequences consisting alternately (within an experimental session) of short runs of trials with feedback (feedback sequences) and without feedback (no-feedback sequences). In Experiments 1 and 2 (absolute identification of sound intensity and sound frequency, respectively), judgmental accuracy was the same in the feedback and the no-feedback sequences, contrary to previous results. Also, in the feedback sequences, the dependency of the current response on the immediately preceding stimulus was larger than that in the no-feedback sequences, while the dependency on the previous response was larger in the no-feedback sequences. In Experiment 3 (absolute identification of sound frequency), we attempted to separate the effects of the number of response categories on sequential dependencies from the effects of the number of stimuli. The results showed that the number of response categories had a larger effect than the number of stimuli on most aspects of performance, but that both affected sequential dependencies. These results are generally consistent with a theory of absolute identification in which feedback affects judgmental accuracy by improving long-term memory for judgmental anchors, while feedback affects sequential dependencies by altering response biases.     

The Impact of Job Insecurity on Counterproductive Work Behaviors: The Moderating Role of Honesty–Humility Personality Trait

The detrimental effects of job insecurity on individual and organizational well-being are well documented in recent literature. Job insecurity as a stressor is generally associated with a higher presence of negative attitudes toward the organization. In this article, the moderating role of Honesty–Humility personality trait was investigated. It was assumed that Honesty–Humility would function as a psychological moderator of the job insecurity impact on counterproductive work behaviors. Participants were 203 workers who were administered a self–reported questionnaire. Results confirmed that job insecurity was positively related to counterproductive work behaviors whereas Honesty–Humility was negatively associated to them. More importantly, Honesty–Humility moderated this relationship, even after controlling for gender, age, type of contract, and the other HEXACO personality traits. For individuals with low Honesty–Humility, job insecurity was positively related to counterproductive work behaviors, whereas for individuals with high Honesty–Humility, job insecurity turned out to be unrelated to counterproductive work behaviors.     

Predicting social behavior from personality traits

The classic view of traits as dispositions was examined and a number of ambiguities noted. When clarified, implications for predicting social behaviors from personality variables were derived. Two types of behavioral criterion were delineated, and it was argued that personality measures should be systematically related to multiple act criteria, but not necessarily to single act criteria. It was suggested that behaviors could be treated as items on a behavioral measure of personality and that standard scaling criteria be applied in identifying behaviors that should be related to a given trait dimension. In attempting to identify behaviors which are linearly related to a personality trait, the application of Bayes theorem was shown to be of theoretical interest. Two indices, a validity index and a linearity index, were derived from Bayes theorem and it was shown that validity is a necessary but not sufficient condition for linearity.     

判断预测的心理偏差及产生机制

心理学对判断预测的研究主要关注预测的偏差及产生机制。判断预测中的偏差有两类：偏见和不一致。偏见主要表现：趋势阻尼;提高效应;给预测结果增加随机噪音。不一致包括：信息获得导致的不一致;信息加工导致的不一致。偏差的出现一是与信息加工过程有关,二是与序列的特征与呈现方式有关。研究发现提供反馈、分解、组合和建议采纳等策略可以增进判断预测的准确性。     

A cross-cultural study of relationships between daily social interaction and the five-factor model of personality

Two studies, one in the United States (N = 130) and another in Germany (N = 100), examined relationships between daily social interaction and the traits of the Five-Factor Model. In both studies, student participants described their social interactions for 2 weeks using the Rochester Interaction Record. In both countries, Agreeableness and Conscientiousness were positively related to reactions to social interaction, whereas Neuroticism was unrelated to reactions to interactions. In the United States, Extraversion and Openness were positively related to reactions to interactions, whereas these factors were not related to reactions to interactions in Germany. In the United States, Extraversion was positively related to how socially active participants were, whereas none of the FFM traits was related to amount of social interaction in the German sample. In both countries, Extraversion was positively related to percent of interactions involving friends. The results highlight the importance of taking into account the sociocultural milieus within which personality unfolds.     

Differences in human ability to judge veracity from the audio medium

The few past studies in this topic area have consistently found that human subjects, as a group, are able to judge veracity better than chance; but no findings have been published relating individual differences to judgmental accuracy. Thus the present study was designed as a first step in filling this knowledge gap. To create a stimulus set of lies and truths, which listeners would later judge for veracity, a method was employed that generated 10 audio-tape recorded lies and 10 audio-tape recorded truths. Each of 100 subject-listeners judged each audio-tape for veracity, and also provided information on a set of personological variables. Listener, as a group, were significantly better than chance in accurately judging veracity (p < .001). In addition, a set of personological variables (social intelligence, field dependence/independence, number of siblings, TV viewing habits, and confidence in judgments) was identified that accounted for 22% of the variance in accuracy (p < .0002). It is acknowledged that these findings are tentative and will require replication before they can be regarded as reliable or valid.
