Synopsis
Team Intelligence (2025) shows a surprising truth: great leadership is not really about the leader. It’s about building teams that work together to be much better than each person alone. This book looks at what makes a team smart. It explains why teams of very skilled people often don’t do well. It also shows how people like Steve Jobs did amazing things without being a typical leader. The book also lists the clear actions that help a group become truly clever.
What’s in it for me? Thinking differently about successful teams.
What makes a team really successful? Experience, very skilled people, good plans. At least, that’s what the teams behind some very big business failures believed.
The failure of the streaming service Quibi shows this perfectly. The company got almost two billion dollars. A very important person from Hollywood, Jeffrey Katzenberg, led it. Former HP CEO Meg Whitman managed the daily work. Even with expensive shows and a lot of advertising money, the service closed down in just six months.
Then there was Google Glass. It had very modern technology and famous people promoted it. But the one-thousand-five-hundred-dollar first version became a joke. It was not allowed in many places. People who wore them were called “Glassholes.”
As these failed projects show, putting together the cleverest people does not always lead to success. More than just one person’s cleverness, what is needed is team intelligence. This is a group’s ability to do different tasks together. It means they talk well, share ideas, and plan their thinking to get great results.
This summary will explain the main ideas of team intelligence: what it is and how to use it well. Ready? Let’s begin.
Blink 1 – Smart teams are connected through trust
Neanderthals are often joked about as “stupid cavemen.” But they were actually stronger and smarter than early humans. So, why did we survive, and they didn’t? The reason is group size. Neanderthals lived in small groups of ten to fifteen people. Early humans formed communities of one hundred to one hundred and fifty people. Forming large groups and working together has always been humanity’s best skill.
This old benefit is still true in today’s business world. New companies with more than one founder are 30 percent more likely to get money than those started by one person. Yet, most companies don’t fully use the power of teams.
The usual way of leading follows a “waterfall” method. This means you train top leaders very well, and the good results slowly spread down. Sometimes it works. But there’s a better way. When Eisenhower started America’s main road system, based on Germany’s motorways, he wasn’t just building roads. He was creating connections. The system linked cities, factories, and materials across the whole country. This changed the economy a lot.
This same idea works for how teams are set up. In a normal “waterfall” structure with nine people reporting to one manager, there are only nine relationships. Everything goes through the manager, who controls the flow. But when team members connect with each other like a national road system, you create forty-five different connections. Information moves where it’s needed without slow-downs. The team works like a brain, sending messages everywhere.
How do leaders build these connections? Through trust. Trust is very important for a group’s cleverness. Trust allows information to flow easily between members. It stops information from getting stuck with just one manager. It helps people work together without always being watched. And it creates a safe feeling where team members really share what they know and say when they make mistakes.
Two special ways help to build this trust. The first is called the IKEA effect. This idea about how people think says that we value things more if we helped create them. Think about the pride you feel for furniture you built yourself, just because you put in the effort. That same feeling of ownership moves to the workplace. When team members work closely together on a project, they care more about the result – and about each other.
The second way is the vulnerability loop. This happens when one person says they are not sure or made a mistake. Then, another person shares their own weaknesses instead of judging. Research shows that showing weakness doesn’t come after trust. It comes before it. As a leader, when you say you have weaknesses and make mistakes, you create a trusting and safe atmosphere, starting from the top.
Blink 2 – Hire your “glue players”
So, we’ve shown that trust builds team intelligence. Now let’s look at what a team is made of. Can a team have too many skilled people? Surprisingly, the answer is yes.
It seems strange, but studies suggest a team can suffer from having too much ability. When more than about 60 percent of a team has very high-performing members, how well the team works starts to get worse. Even World Cup football teams have been shown to play worse when they have too many top players.
What is the best way to know if a team will succeed? It’s something called task interdependence. This is how much team members must work together and depend on each other to finish their work. In football, this means players passing the ball, getting into position to receive it, and making room for teammates. It is not about constantly trying to score by themselves. High task interdependence needs teamwork. Low task interdependence allows for success alone.
But here’s the problem. Good task interdependence often means people must give up their own fame for the team’s goals. For group cleverness to grow, people must often give up their own importance and prizes. They also need to feel safe to speak their mind, no matter their rank in the company.
This means seeing the worth of the glue players. This term comes from basketball (NBA). It means athletes who do the less exciting work that makes everyone else better. Their scores might not be impressive. But they do the work that helps other players improve: they block opponents, play defense, and pass to open teammates.
There’s a strong similarity in scientist William Muir’s experiments with chickens. Muir tried breeding “superchickens” together. These were the chickens that laid the most eggs. After six groups, the results were terrible. Only three birds were left. They had killed each other because they were too competitive. Meanwhile, another group of chickens was chosen for being friendly. These birds got along well. They did very well and laid many more eggs. The aggressive superstars ruined their group, while the cooperative birds made everyone better.
This lesson applies straight away to teams. By giving praise for working together, and by seeing the value of team help that can’t easily be measured – like helping at the right time, making people feel better, or solving problems – even a group of very skilled people can become a superstar team.
Blink 3 – Smart teams act with the same goals
Trust and “glue players” give us the basic parts for a high-performing team. But just having the parts doesn’t make a meal. We need to know how to put them together to make things happen.
Anita Williams Woolley at Carnegie Mellon University has spent years studying this. She does interesting tests. She brings groups of strangers together and gives them difficult jobs. These jobs are everything from doing picture puzzles to thinking up new business ideas.
Her research shows that group cleverness comes from how people talk and work together, not from one person’s intelligence score. The best-working groups have three things in common: members talk for about the same amount of time, they are good at understanding what others are feeling and thinking, and importantly, they often include more women. Women usually score higher at understanding social situations.
These ways of working together form fast, often in the first few meetings. As a leader, you help decide which ways of working become normal. Sometimes, the best move is to not get involved at all. When one person takes over or people fight for control, the team’s cleverness gets worse. Has your boss ever left for a few days, and you noticed how everyone suddenly starts working harder? That’s what happens with shared leadership.
Of course, most companies still need specific managers. If you are in that position, you’ll need to change how you lead to help this cleverness grow.
Your main job becomes making sure everyone shares the same goals. About 60 percent of employees don’t know their company’s main goal. This lack of clarity is said to cost US companies around four hundred and fifty billion dollars each year. To fix this, use the army idea of a commander’s intent. This is a clear reason for the work. It helps soldiers make new decisions when plans go wrong.
You make things clear by saying them again and again. Instead of only saying the goals once at a start meeting, put them into everyday talks. Do this until the goal becomes something everyone knows without thinking. You might even choose a “goal helper.” This person’s job is to link daily tasks to the main aim. This becomes very powerful when you connect how well the team works to people’s personal goals, like having enough time for work and for life. When you see someone acting according to the main goal – someone making a decision that clearly helps the mission – praise it openly. After all, when you’re all working with the same goals, that’s a reason to celebrate.
Blink 4 – Focus, focus, focus
In the 1930s, a carpenter from Denmark named Ole Kirk Christiansen started making wooden toys. He called his company Lego. Within a few decades, the company changed to making plastic bricks that fit together and became very successful. By 1999, the company had sold about 203 billion Lego bricks worldwide.
Then came trouble. Video games were making children interested all over, and Lego got very scared. What was their response? Trying too many new things too fast. They had new types of products every few months, theme parks, electronic toys, products linked to films. The company was like a company with attention problems. By 2004, Lego was losing hundreds of millions of dollars each year.
This failure teaches a hard lesson. If you want to make a smart team stupid, just make them focus on too many things.
Smart teams avoid the mistake of always talking. Instead, they use what the author calls bursty communication. This means short, strong team working times. These are followed by long periods of working alone without being disturbed. Think about planned short daily meetings or specific times just for working together. This frees up the rest of the day for serious concentration.
It seems strange, but the most effective teams actually make communication harder. They set times when no emails are sent. They expect people to try to solve problems by themselves first, before sending a message. They cut meetings hard, keeping only what is absolutely essential.
Lego’s recovery depended on this same idea. A new CEO did not try to find fast solutions. He went back to basics, cutting 30 percent of its products. By 2005, the company was making money again with sales over a billion dollars.
But Lego added something else: “Firesides.” These were one-on-one talks anyone could ask for with anyone in the company. The rule? The listener must not stop the speaker. They could only offer what Lego finally understood was their most valuable thing: full, focused listening.
Blink 5 – Roles and resources
Now, while it’s best to tell people not to steal very expensive diamonds, there are some important lessons we can learn from Leonardo Notarbartolo. He was the clever person who planned the Antwerp diamond robbery. His work shows us how to build a team very well, and we can actually use these ideas.
In 2003, Notarbartolo and his group managed to do what was called the biggest robbery of the century. Their target was the Antwerp Diamond Centre. This was a safe protected by ten different security systems. These included alarms for heat, movement, magnetism, and ground shakes. It also had a lock that had one hundred million different ways to open it.
To get into this very strong place, Notarbartolo chose people who were very good at one thing, not good at many things. There was the King of Keys, who was very skilled at opening locks. The Genius, who could turn off difficult alarm systems. The Monster, who managed the planning and heavy lifting. Each person brought one, very special skill that no one else had. They studied, they practiced, and in one weekend, they got past every security system. They left quickly with over one hundred million dollars in diamonds, gems, and gold.
The lesson here is clear. If you want to do something hard – or something that looks impossible – put together a team with clear roles that work well together.
Teams with different kinds of skills show more group cleverness. When everyone brings different special knowledge to the table, the group can solve problems in many ways. A software team needs both the person who plans smart systems and the person who finds hidden mistakes.
But having different skills is only one part of the solution. Differences in people like race, gender, and background also makes the team smarter. Different life stories mean different ways of seeing things. This helps the team to see things they might not have. It also helps them to question old ideas that groups of very similar people completely miss.
Notarbartolo’s group succeeded because each expert knew what to do. They trusted the others to do their parts. The same idea applies to your team – but without the crime part.
Blink 6 – Managing bad team members
Finally, it’s time to answer the question you might have been thinking about this whole time: what if someone on your team just doesn’t like working with others? We’ve all had to manage bad team members. This is the colleague who says they did work that others did. Or who secretly works against decisions in a sly way. Or who makes people feel worried wherever they go. It’s not pleasant. But, with the right management, this bad team member won’t make the team less clever.
First thing to note: someone who once took your sandwich from the shared fridge or spoke to you sharply when you were busy is not a bad team member. We all have bad days and do things we wish we hadn’t.
Real bad behavior often comes from three personality traits: a strong need to be praised, not caring about others’ feelings, or cleverly tricking people to get what they want. Here is the hard truth: these people often make the team succeed exactly because of these bad traits. Their hard actions, never-giving-up energy, and strong ambition can push things forward when others might stop.
Take Steve Jobs, for example. Many people said he was a perfect example of a self-centered person. He treated people badly, ignored them, and asked for too much. In 1985, Apple’s leaders decided they had enough and removed him. What happened? Apple almost failed. When Jobs returned in 1997, the company became very successful again quickly. His ideas and strong energy, the very traits that made him difficult, were part of his amazing cleverness.
This leaves leaders with a hard problem. How do you manage bad team members without losing their good work or letting them ruin the team spirit?
The smart plan involves what’s known as buffering. This means making sure your team is balanced from the start. When hiring, change what you look for. Choose people who are good at working with others and show real ability to work with them. During interviews, watch for those who ask good questions about how the team works. Pay attention to people who describe achievements using “we” rather than “I.” Also look for those who can explain how they’ve helped others do well.
A team with enough people who link others, solve problems, and help the team stick together creates a kind of immune system. These people don’t just deal with difficult personalities. They can actually turn bad energy into good results. This protects others from the worst impacts.
The goal is not getting rid of every difficult person. Some disagreement can create better ideas. The goal is to make sure that one bad person doesn’t ruin the whole team. Balance is everything.
Final summary
In this summary of Team Intelligence by Jon Levy, you’ve learned that group cleverness depends on how well people work together. It does not depend on the simple intelligence score of the people you hire.
True team intelligence shows itself when everyone takes part equally, when people are very aware of others’ feelings, and when there is controlled, short, intense talks. These talks are followed by deep concentration. Good leadership needs creating a place where this cleverness can grow well. This means making sure people feel safe to speak up. It also means making sure everyone’s own goals match the team’s main goal. And it means appreciating the “glue players” who keep the team connected. The best teams work like a connected system. Trust and information flow directly between members. This avoids the slow-downs that happen in strict top-down systems.
Okay, that’s it for this Blink. We hope you enjoyed it. If you can, please take the time to leave us a rating – we always appreciate your feedback. See you in the next Blink.
