Moreover, understand the pitfalls of standardization and the essentiality of overcoming biases to maximize collective intelligence and achieve unparalleled success.

The Danger of Collective Blindness

The habit of surrounding ourselves with like-minded people can significantly impede the success of a team. This phenomenon, called homophily, creates collective blindness, preventing individuals from recognizing things they are not seeing. Even the most intelligent teams can suffer from this, especially if they all think similarly. The CIA’s recruitment patterns before 9/11 serve as an example of this phenomenon. The predominance of white males from the middle and upper classes who had studied liberal arts in college made the CIA agents overlook important clues about Osama bin Laden’s growing influence. To overcome this, one must embrace the rebel within, stepping beyond collective blindness and seeing things from different perspectives.

The Power of Cognitive Diversity

Cloning the best economist may not guarantee the most accurate team. Building a team with cognitive diversity is important in solving complex problems because it requires a range of perspectives and approaches. It is not enough to consider demographic diversity alone. Achieving cognitive diversity takes a thorough understanding of a candidate’s specific skill set. Cognitive diversity leads to increased group wisdom, which is important in making correct predictions. Alastair Denniston’s team during WWII was successful because it was both demographically and cognitively diverse and fostered in the right way. A diverse team needs to thrive on open communication, willingness to learn, and mutual respect.

Overcoming Dominance Hierarchy in the Workplace

In the workplace, cognitive diversity is often stifled by dominance hierarchy – a lurking ‘structure’ that silences non-leaders. This article argues that effective leaders must foster open communication and create psychological safety, paving the way for ideas sharing. The death of twenty people on a flight to Portland in 1978 exemplifies the dangers of ignoring cognitive diversity. Although doing away with leaders altogether might create more problems, using a simple technique like brainwriting to ensure all employees’ voices are heard can overcome the challenges of dominance hierarchy. Creating this atmosphere unlocks the potential to generate brilliant ideas that can lead to groundbreaking solutions.

The Power of Outsider Thinking

Successful entrepreneurs with roots outside the US share a common trait – the ability to think innovatively. Being an outsider primed their brains for unique solutions and allowed them to combine concepts in original ways. To cultivate outsider thinking, we should expose ourselves to diverse fields of interest and connect with a network of people from different backgrounds. By doing so, we can generate groundbreaking ideas and drive innovation.
