Professor Scott E. Page, an American social scientist and his colleagues, have used computational experiments to study the decision-making performance with complex decisions. He found that random ("diverse thinking”) groups of problem solvers can routinely outperform groups of experts.
This happens because experts tend to have a consensus approach to problem solving, whereas a diverse group are likely to use a much broader range of tactics. They can conceptualize problems in new ways and increase the potential solutions available to them. Experts can still play a role in addressing complex problems. However, it is better to have a diverse group of them.

The term Groupthink was coined by Irving Janis (1918 - 1990). If a group becomes overly cohesive they may minimize conflict and rush to consensus instead of properly considering alternative options.
Warning signs for the presence of groupthink include:
Diverse thinking groups have difference in their mindsets and worldviews. They can avoid the unchallenged decision-making characteristic of groupthink by making decisions based on facts instead of influence, authority or group allegiance.
Diversity (noun) The condition of having or being composed of differing elements;
Diversity is far more (diverse!) than more externally observable such as gender, age, ethnicity and even sexual orientation or disability/ability. There are numerous other characteristics that could be considered - such as different ways of addressing problems (cognitive diversity), differences in experiences, skills or beliefs.
An individual is not inherently diverse or non-diverse, instead the presence or degree of diversity is related to who an individual is compared to.
The concept of diversity of thought is based on the idea that thinking is shaped by our culture, background, experiences, and personalities.
