Bias: Groupthink effect
Definition of the bias: Definition of the Bias - Groupthink is a bias that occurs when the desire for group harmony or consensus overrides critical thinking and the consideration of alternative viewpoints. It often results in one-sided or poorly evaluated decisions.
Here are examples of how groupthink bias may manifest in educational settings
Classroom Discussion Assumptions: while discussing a controversial topic like climate change, a few vocal students dominate the discussion, emphasizing that "individual actions are insignificant compared to government policies." Other students with alternative perspectives, such as the importance of personal responsibility, remain silent to avoid disrupting the group consensus. The discussion becomes one-sided, missing key viewpoints.
IMPACT: Groupthink can suppress diverse opinions, especially on sensitive or controversial topics, leading to a lack of critical thinking and balanced learning.
Classroom Performance / Group Projects: in a group project analyzing solutions for reducing poverty, the team quickly agrees on a single solution suggested by a confident student without exploring alternative approaches. Their final presentation is one-dimensional and fails to meet the teacher's expectations for a multifaceted analysis.
IMPACT: Groupthink in group projects can result in shallow work, as conformity and the dominance of one voice hinder creativity and thorough analysis.
Homework Expectations / Feedback on Assignments: a teacher assumes that students all agree with the grading criteria provided at the start of the semester because no one raises objections. In reality, several students feel the criteria are unclear or unfair but don’t voice their concerns, believing their peers accept them.
IMPACT: Groupthink may prevent students from seeking clarification or constructive feedback, leading to unmet learning needs and dissatisfaction.
Technology in the Classroom: during a staff meeting, the principal proposes that all teachers integrate a specific app for classroom management. Most teachers agree without questioning its effectiveness, assuming that their peers are fully on board. However, some teachers privately struggle with the app's functionality or find it unsuitable for their teaching style but hesitate to raise concerns.
IMPACT: Groupthink can lead to uncritical adoption of tools or technologies that may not suit diverse teaching or learning needs, reducing effectiveness and satisfaction.
Parental Assumptions: at a PTA meeting, parents discuss the introduction of sex education into the curriculum. A few outspoken parents argue against it, claiming it’s inappropriate. Other parents, including those who support it, remain silent to avoid conflict. The group ultimately opposes the program without thoroughly considering the benefits or broader perspectives.
IMPACT: Groupthink in parent-teacher discussions about controversial topics can lead to decisions that are not representative of the broader community’s views or the students’ best interests.
In-class activity
Below is an activity in which you can use the same situation for teaching purposes. Please first read the scenario to your students and then have them discuss the situation and its implications. You can use the information provided to guide your class discussion.
Scenario
Ms. Carter, a high school teacher, assigns two groups of students to work on a project analyzing solutions for reducing income inequality. The project requires students to consider diverse perspectives, including government intervention, community-based programs, and private sector initiatives, and to present a balanced, well-researched analysis.
Group A: The group initially brainstorms multiple solutions but quickly settles on a government-focused approach due to the dominance of one vocal activist student who dismisses alternative ideas. As a result, their presentation is detailed but one-sided, lacking consideration of other perspectives.
Group B: The group holds a democratic discussion, where every member contributes ideas, and they explore various solutions. However, due to time constraints and a lack of structure, their analysis is shallow and fails to meet the expectations outlined by Ms. Carter.
Ms. Carter provides clear task instructions emphasizing the need for high-quality, multifaceted solutions. However, she does not address potential group dynamics as the students are not used to such group work.
Teaching points:
This scenario illustrates how groupthink bias can lead to suboptimal outcomes by prioritizing consensus or conformity over critical evaluation and balanced decision-making.
Impact on Educational Settings:
Students: Groupthink can suppress dissenting opinions, limit creativity, and lead to incomplete or biased outcomes in group projects or discussions.
Teachers: It can prevent teachers from recognizing diverse student needs or addressing conflicts effectively in classroom group work.
Overall: Groupthink reduces opportunities for critical thinking and balanced decision-making, which are essential in educational environments.
How to Overcome This Bias:
Encourage Dissent: Assign a “devil’s advocate” in group projects to ensure alternative perspectives are explored.
Set Clear Roles: Provide students with structured roles in group work (e.g., facilitator, timekeeper, note-taker) to balance participation.
Model Critical Thinking: Show students how to critically evaluate ideas rather than seeking quick consensus.
Monitor Group Dynamics: Teachers should check in with groups to ensure all voices are heard and one perspective doesn’t dominate.
Teachers Can Use This Example To...
Highlight how group dynamics influence outcomes in collaborative work.
Demonstrate the importance of managing groupthink in both student projects and professional meetings.
Teach students the value of critical thinking and respectful dissent.
Discussion Questions
1. How did the group dynamics in Group A lead to a one-sided outcome?
2. What strategies could Group B have used to manage their time more effectively while maintaining a democratic process?
3. As a teacher, what specific steps could Ms. Carter have taken to prevent groupthink from influencing the groups?
4. Why is it important to include diverse perspectives when analyzing complex issues like income inequality?
5. Can you think of a time when groupthink influenced a decision you were part of? What could have been done differently?
