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.

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.

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.

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.

Ethnic Diversity Reduces “Groupthink,” Economic “Bubbles”

Most people are unlikely to trust recommendations and evaluations from people of different ethnic groups.

Sheen Levine

However, this bias may reduce the “herd mentality” that characterized price “bubbles” in U.S. housing and global financial markets, reported Columbia’s Sheen S. Levine, Evan P. Apfelbaum of MIT, Goethe University’s Mark Bernard, Texas A&M’s Valerie L. Bartelt, Edward J. Zajac of Northwestern, and University of Warwick’s David Stark.
They concluded that, “Diversity facilitates friction that enhances deliberation and upends conformity.”

Economic “bubbles” occur when the majority of traders set inaccurate prices, probably influenced by a type of  “groupthink.
This cognitive error results in a mismatch between market prices and true asset values.

Irving Janis

Groupthink can occur when three conditions interact, according to Yale’s Irving Janis:

  • Group Cohesiveness
    • Deindividuation” occurs when group belonging becomes more important than individual dissenting views,
  • Group Structure
    • Homogeneity of group’s social backgrounds and ideology,
    • Group insulation from feedback,
    • Lack of impartial leadership,
    • Lack of norms to conduct systematic analysis and clearly structured decision procedures,
  • Context
    • Stressful external threats,
    • Recent failures,
    • Decision-making difficulties,
    • Moral dilemmas.

      Scott E. Page

A wider range of viewpoints leads to less groupthink and more balanced decisions in a mathematical model developed by University of Michigan’s Scott E. Page and Lu Hong of Loyola University.

Diverse groups ran into fewer “dead ends” when they developed solutions than did groups comprised of individuals who tended to think similarly.

Likewise, Georgetown’s David A Thomas and Robin J. Ely of Harvard confirmed that identity-diverse groups can outperform homogeneous groups
summarized in a formula:

Collective Accuracy = Average Accuracy + Diversity.

To test the impact of group diversity on market “bubbles,” Levine’s group constructed experimental markets in Singapore and Texas, USA, in which participants traded stocks to earn money.

Evan Apfelbaum

More than 175 volunteers with backgrounds in business or finance were randomly-assigned to groups of six ethnically-homogeneous or ethnically- diverse participants.

Traders knew the ethnic composition of their groups, but they couldn’t communicate with each other.
In addition, their “trades” of dividend-paying stock were anonymous.

Homogeneous groups set inflated selling prices, yet traders in those groups bought the stock, resulting in increasing stock prices.

Mark Bernard

In contrast, traders in diverse groups refused inflated selling prices, so the stock price fell to approximately the price in an “ideal” market with “rational” traders.

When traders and other decision-makers come from similar ethnic, social, and attitudinal backgrounds, they tend to place undue confidence in others’ opinions, and tend not to subject them to rigorous analysis.

Valerie Bartelt

As a result, people in homogeneous may be more likely to accept prices and deals that deviate from actual underlying values.
Levine’s group concluded that “homogeneity…imbues people with false confidence in the judgment of coethnics, discouraging them from scrutinizing behavior.”
