How Accurate are Personality Judgments Based on Physical Appearance?

Laura Naumann

People pictured in full-body photographs were evaluated by volunteers for likeability, self-esteem, loneliness, religiosity, and political orientation based on their photographed clothing and non-verbal behaviours. 

Simine Vazire

This study, conducted by Sonoma State University’s Laura Naumann, with Simine Vazire then of Washington University, teamed with University of Cambridge’s Peter Rentfrow, and Samuel Gosling of University of Texas, also investigated volunteers’ accuracy in judging Big Five personality traits (Openness, Conscientiousness, Extroversion, Agreeableness, and Neuroticism), proposed by Paul Costa and Robert McCrae of the U.S. National Institutes of Health

These ratings were compared with evaluations by people acquainted the photographed person.

Observers’ judgments were accurate for extraversion, self-esteem, and religiosity when people were photographed in a standardized pose.
Raters were correct for additional personality traits when judging photographs in spontaneous informal poses.

Paul Costa

These findings suggest that candid photographs provide more accurate cues to some personality characteristics than planned poses.

Robert McCrae

Robert McCrae

Judgments based on clothing cues were associated with less accurate judgments of personality characteristics.
In contrast, facial expression and posture enabled observers to make more accurate judgments.

John Irving

Observers can make accurate inferences about some personality characteristics based on visual cues, according to these findings.
Novelist John Irving’s A Prayer for Owen Meany noted that “Things often are as they appear. First impressions matter,” just as these researchers concluded.

When Do Women Talk More than Men?

Women talk more than men.
Women talk less than men.

-*Which is true?

It depends.

Social context and expectations determine when females talk more than males, according to NYU’s Kay Deaux and Brenda Major of University of California Santa Barbara.

One investigation used electronic audio monitoring devices (digital “sociometers”) to identify gender associated with talk volume during a work collaboration project, and during lunchtime social conversations at work. This study was conducted by Harvard’s Jukka-Pekka Onnela and Sebastian Schnorf, with David Lazer of Northeastern and MIT colleagues Benjamin N. Waber and Sandy Pentland.

During the work project women talked significantly more than men, except when groups included seven or more people.
In contrast, women spoke less than men in larger groups during the work project.  
In addition, women sat closer to other women in larger project groups.

Sebastian Schnorf

During social conversations, women talked the same amount as men, and more than men when the group was large.
Group size is associated with women’s verbal participation in groups depending on the task focus vs. social focus.

Matthias Mehl

These findings support earlier reports of equal verbal participation by women and men by University of Arizona’s Matthias R. Mehl, collaborating with Simine Vazire of Washington University in St. Louis. Their collaborators included University of Connecticut’s Nairán Ramírez-Esparza, with Richard B. Slatcher of Wayne State and University of Texas’s James W. Pennebaker.
This team analyzed voice recordings from more than 390 participants, and concluded that women and men both spoke about 16,000 words per day.

Women in large group social settings spoke more than women in collaborative work projects, found Onnela’s team.
The strongest difference in gender participation related to relationship strength and group size.

These results have implications for work groups that develop problem solutions and innovations.
Contributions from all women and men in diverse work groups are required to produce the largest number and most innovative solutions, according to Loyola University’s Lu Hong and Scott E. Page.
They found that diverse work groups produce superior solutions compared with homogenous groups, even if groups were composed of uniformly top performers.

In fact, a group’s “general collective intelligence factor” is most closely associated with:

  • Proportion of females in the group,
  • Average social sensitivity of group members,
  • Equal conversational turn-taking.
Anita Wooley Williams

This “collective intelligence factor” was not related to the average or maximum individual intelligence of group members, found Carnegie Mellon’s Anita Williams Woolley, Christopher F. Chabris of Union College, with MIT colleagues Sandy Pentland, Nada Hashmi, and Thomas W. Malone.

Women can apply these insights by increasing verbal participation at work to establish visibility and credibility, while contributing to group performance.

Gender Differences in Emotional Expression: Smiling

2 Replies

Previous blog posts have outlined dilemmas women face in being seen as competent yet  “likeable” in negotiations.

Deborah Gruenfeld

Deborah Gruenfeld

Deborah Gruenfeld of Stanford and researcher Carol Kinsey Goman note that women can increase perceived authority. if they smile when situationally-appropriate instead of consistently.

Simine Vazire

Simine Vazire

They imply that observers assign different interpretations to women’s smiles than to men’s smiles.
Washington University in St. Louis’s Simine Vazire teamed with Laura Naumann of University of California, Berkeley, University of Cambridge’s Peter Rentfrow, and Samuel Gosling of University of Texas to investigate gender differences in the meaning of smiling behavior.   

Jacob Miguel Vigil

Jacob Miguel Vigil

They drew on University of New Mexico professor Jacob Miguel Vigil‘s theory that emotional behaviors promote attraction and aversion, based on others’ perceived:

  • Power to provide resources or harm (dominant, masculine behaviors)
  • Trustworthiness to reciprocate altruism (submissive, feminine)

Laura Naumann

Laura Naumann

Vazire’s team reported that women’s smiles signal positive affect and warmth, which are seen as “trustworthiness cues” in Vigil’s model, and typically attract fewer, but closer relationships.
Gruenfeld and Goman argue that women’s smiling also signals low power in negotiation situations and interpersonal interactions.

Peter Rentfrow

Peter Rentfrow

In contrast, smiling among men indicates confidence and lack of self-doubt, seen as “capacity cues” to the ability to either help or hurt others.
These expressions usually attract numerous, but less-intimate relationships while
conveying a key element of power, self-assurance.

Samuel Gosling

Samuel Gosling

Team Vazire’s research validated Gruenfeld’s and Goman’s hypothesis that observers interpreted women’s smiles differently than men’s, even if the underlying, subjective emotional experience is similar.

Their work supports  Gruenfeld’s and Goman’s recommendation that women balance smiling, a signal of interpersonal warmth, with powerful non-verbal behaviors to achieve best outcomes in negotiations and workplace performance.

-*How has smiling helped establish your warmth?
-*When has smiling undermined your credibility and power?
