Key idea 1 of 7

What’s in it for me? Learn how to optimize your chances of success in the face of complex challenges.

Imagine you had access to an ultimate, cutting-edge ideas generator. How would it revolutionize your business, cause or research? And what might happen if you plugged your brilliant generator into someone else’s, to combine their power?

The truth is, we all have access to a generator like this. Perhaps you think that your brain can play the role of Ultimate Ideas Generator. While it’s undeniable that intelligence is essential in solving complex challenges, there’s another fundamental ingredient we must seek out, find and integrate into the mix if we want to be successful.

This ingredient has extraordinary powers. It can make blind-spots vanish, broaden our expertise exponentially, and tease out every infant idea and help it flourish.

As you’ll learn in these blinks, that ingredient is cognitive diversity – diversity of the minds we engage with. Once you’ve learned how to harness its power, you’ll be a monumental force.

In these blinks, you’ll learn

that meetings are often fatal for brilliant ideas;
why thinking like a migrant can make you be more innovative; and
how spotting German swear words helped Britain crack codes.

Working with people who are similar to us undermines our potential for success.

Imagine you’re a CEO recruiting a new financial manager. The final two candidates are equal in merit and experience. One shares your views on company policy, while the other has voiced some concerns about your five-year plan. Who should you hire?

We tend to surround ourselves with people we identify with, in appearance, beliefs and perspective. This subconscious habit, known as homophily, occurs because it’s validating to have our own ideas reflected back to us by the people around us, whether it’s friends, family or colleagues. But the truth is that homophily significantly inhibits the success of a team.

The problem with homophily is that it creates collective blindness. Even if a team is made up of highly intelligent individuals, if they all think in similar ways, they won’t be aware of what they’re not seeing. These blind-spots often aren’t the result of failure on any one individual’s part. They can arise from incidental factors we can’t control, like the culture we grew up in or who our university professors were.

We can see the devastating consequences of homophily if we look at the CIA’s past recruitment patterns. Prior to 9/11, the CIA had a long tradition of predominantly hiring officers who mirrored existing staff: white males from the middle and upper classes who had studied liberal arts at college.

This homogeneity meant that, despite having thousands of personnel with a formidable budget at their disposal, CIA agents suffered from collective blindness. They overlooked important clues about Osama bin Laden’s growing influence. Their lack of understanding about Islam, for instance, led them to dismiss him as primitive because he lived in a cave, had a long beard and wore a simple cloth robe. They failed to recognize that he had deliberately modeled himself on the Prophet, and that a cave is a deeply religious symbol to Muslims. Their blindness meant they underestimated the threat bin Laden posed, contributing to the horrifying tragedies that took place in America on September 11, 2001.

So, how do we overcome homophily if it’s part of human nature? In the blinks that follow, you’ll discover how to step beyond collective blindness by embracing the rebel within.

When solving complex problems, diversity is just as important as intelligence.

Consider this hypothesis: if the fastest relay team can be created by cloning Usain Bolt, then the most accurate team of economists can be created by cloning the world’s most competent forecaster. Makes sense, doesn’t it?

Although the statement above seems logical, it’s incorrect. Tackling complex problems demands more than just intelligence and skill. It demands diversity. And this diversity shouldn’t be limited to demographic attributes, like gender, race, age, sexual orientation or religion. It must be a diversity of the mind, or cognitive diversity, something we wouldn’t achieve by cloning our genius forecaster, since we’d be replicating the same brain.

Without effective communication, the benefits of diversity are lost.

Have you ever been in a meeting with your stomach in knots because you disagree with what your boss is saying but don’t feel comfortable objecting? Or perhaps you have a brilliant idea to contribute, but between your manager and your assertive colleague, it’s impossible to get a word in edgewise.

These scenarios are common in even the most inclusive workplaces because of dominance hierarchy. In any group situation, either a leader will be appointed or one will emerge. And because humans have been operating under hierarchical social structures for thousands of generations, we often don’t even notice them. But these structures are a menace to cognitive diversity because they silence non-leaders, just like you were silenced in your meeting. Unless leaders foster open communication, ideas like yours are lost.

To be truly innovative, a diverse team must be made up of individuals who are diverse within themselves.

What do Ariana Huffington, Sergey Brin and Elon Musk have in common? Well, they’re all successful entrepreneurs based in the US but they have something else in common too. They were either born outside the US or their parents were. And being an outsider primes the human brain for innovative thinking.

Innovation can occur slowly over time – as it does when a species evolves – or it can happen quickly when two concepts collide in an exciting and unexpected way. People who aren’t frequently outside their comfort zones are less likely to experience these bursts of inspiration, because their minds have settled into what’s familiar. This is why many influential innovators and entrepreneurs are migrants, or children of migrants, since they’re not accustomed to the quirks and characteristics of their new homeland.

To nurture our cognitive diversity, we must engage with other points of view in meaningful ways.

Imagine you arrive at a party where you only know a few workmates. You’re excited by the prospect of meeting new people. But when you leave a few hours later, you realize you didn’t speak to anyone you didn’t already know. You had a great night, but you didn’t expand your social circle.

It’s part of human nature to seek out people we identify with. Ironically, the broader our social options, the less likely we are to form diverse friendship groups. And while it’s natural to gravitate towards people with similar interests and values, it means we’re at risk of ending up in an echo chamber.

When we impose specific standards on people, we reduce the likelihood of successful outcomes.

Imagine you’re at a friend’s house and someone accidentally spills a jug of juice on you. Your friend lends you some clean clothes but they don’t fit. This is strange because you’re both the same height and a similar weight.

Clothing is just one of many daily encounters we have with standardization. Since few of us can afford a bespoke wardrobe, we purchase clothes in predetermined sizes. But body shapes are diverse, even within a specific size range, which is why your friend’s clothes might not fit you.

Before we can harness the benefits of diversity, we must overcome our biases and be willing to listen.

There’s something very special about learning to read as a child. For many of us, books were an excuse to snuggle into a warm lap while an adult brought meaning to squiggles on a page. Slowly, those squiggles became letters, then words, then sentences, leading to that wonderful moment when we could read independently.

This ability to learn new skills from others sets our species apart. But if we really want to build our collective intelligence – the combined intelligence of a group – we must overcome bias.

Great app. Good selection of book summaries you can read or listen to while commuting. Instead of scrolling through your social media news feed, this is a much better way to spend your spare time in my opinion.
