The science behind groupthink
Groupthink is defined as:
‘the practice of thinking or making decisions as a group, resulting typically in unchallenged, poor-quality decision-making’
Historical examples of groupthink
Janis’ eight symptoms of groupthink
Illusion of invulnerability: Group members create excessive optimism and encourage taking extreme risks.Inherent morality of the group: Group ignores ethical and moral consequences of their decision.Collective rationalisation: Rationalisation discounts warning signs or other information that may lead the group to reconsider their decision.Stereotyping of out-groups: Extreme cynicism by in-group members negates the capabilities and competence of the opposing group.Self-censorship: Avoidance of one’s opinion to minimise deviation from group consensus.Shared illusion of unanimity: Group members who remain silent agree.Pressure to conform: Group members pressure dissenters by making it clear that divergent views are not welcome.Mindguards: A group member acts as an information filter to control the decision-making process towards a specific and limited number of alternatives. [4]
We’ll come back to each of these symptoms later in the course.
Groupthink is relevant to situations large and small
From the previous examples, groupthink may appear to be relevant only on a large scale, but that’s just not true.
Groupthink affects the underlying culture of entire companies and industries.
Groupthink contributes to both faulty research practices and our ability to spot cultural appropriation in our work.
One of the easiest ways to avoid groupthink is to increase the diversity of our hiring practices.
That brings us back around to that initial definition of ‘diversity’. We’re not really talking about diversity; we’re talking about accuracy.
Companies can mitigate, or potentially avoid, the symptoms of groupthink, simply by increasing the proportional accuracy of their employees’ representation of the overall population.
As Dr Claudia Plaisted writes in the Journal of Public Health Management and Practice, the most important reason organisations should promote diversity is not morality. It’s because a diverse group of people brings diverse ways of thinking about things. [5]
In that journal article, Dr Plaisted offers seven steps to create thought diversity and avoid groupthink. We will also explore these proposed steps towards the end of the course.
