Group of penguins, one a different colour


In today's fast-paced business world, the pressure to innovate and adapt is greater than ever. Yet despite our desire for fresh thinking, many teams find themselves churning out the same ideas over and over again. 

If you've noticed a lack of creativity, a stagnation of ideas, or a resistance to change within your team, then it's possible that groupthink may be affecting the quality of your team’s decision making. 

By shedding light on the dangers of groupthink and providing actionable strategies for overcoming it, this piece equips leaders like you with the tools and insights needed to foster a culture of open-mindedness and critical inquiry within your team. Whether you're struggling to innovate in a competitive market or seeking to foster a culture of creativity and collaboration, this article could help you overcome the barriers to success.

What is Groupthink?

Groupthink is a psychological phenomenon that occurs within a group of people when the desire for harmony or conformity in the group can result in an irrational or dysfunctional decision-making outcome. It limits the ability of a group to make well-informed and rational decisions by promoting conformity and consensus at the expense of critical thinking, open debate, and consideration of alternative viewpoints. So why does it happen? Some of the root cause are:

  • Homogeneity: Teams composed of individuals with similar backgrounds, experiences, and perspectives are more likely to agree with one another.

  • Leadership Style: Authoritarian leaders don’t want to be challenged. They want to be agreed with.

  • Lack of Psychological Safety: When team members fear reprisal or judgement for voicing alternative viewpoints, they're less likely to speak up.

  • Time Pressure: Tight deadlines or a rush to reach consensus can inhibit thorough discussion and critical evaluation of ideas.

  • Overconfidence: A false sense of invulnerability or superiority within the group can lead to a disregard for potential risks or flaws in decision-making.

Breaking Free from Groupthink

Put simply, groupthink is a silent killer of innovation and progress. Combat it by actively seeking out input from individuals with varied backgrounds, expertise, and viewpoints to challenge group consensus and foster an environment where team members feel comfortable expressing dissenting opinions without fear of ridicule or reprisal. Here are some helpful ideas to try in your organisation:

  • Assign Devil's Advocates: Designate team members to play the role of devil's advocate, tasked with questioning assumptions and challenging prevailing opinions.

  • Utilise Decision-Making Techniques: Implement techniques such as brainstorming, scenario planning, or the Delphi method (anonymous voting on ideas) to encourage thorough exploration of alternatives.

  • Rotate Leadership Responsibilities: Rotate leadership roles within the team to prevent any one individual from exerting undue influence and to encourage diverse leadership styles.

  • Conduct Post-Mortems: After significant decisions or projects, conduct post-mortem analyses to evaluate the decision-making process, identify potential instances of groupthink, and learn from past mistakes.

  • Encourage Critical Thinking: Cultivate a culture of critical thinking and constructive scepticism, where assumptions are rigorously examined, and decisions are subject to robust scrutiny.

  • Seek External Input: Consult with external experts, stakeholders, or impartial third parties to provide fresh perspectives and challenge group consensus.

By understanding the root causes of groupthink and implementing proven strategies to foster diversity of thought and promote open dialogue, you can break free from its grip and unlock the full potential of your team and create a culture that inspires innovation, growth, and success.

Research shows that diverse teams, where groupthink is less likely to occur, are more innovative. A study conducted by Harvard Business Review Analytic Services found that teams with diverse members, including individuals from different backgrounds, genders, and areas of expertise, were 45% more likely to report that their firm's market share grew over the previous year. This statistic suggests a strong correlation between diversity in teams and increased innovation and market success.
