“A few years ago, a group of researchers at Google set out to answer a question:      why do some teams excel while others, despite being packed with talent, consistently struggle?

They studied meetings, projects, conversations.                                                  They scrutinized resumes, academic credentials and years of experience.

But the more they analyzed the data, the more they realized that the secret didn’t lie in techical pedigree.

One day, they observed a meeting of one of their highest-performing teams.

An engineer said: “This might be a silly question, but I didn’t quite catch this step.”

Another added: “I actually have a different perspective.”

Someone else admitted: “I think I made a mistake.”

No one laughed. No one judged.

The discussion continued and the ideas grew stronger.

It was then that the researchers made a breakthrough: the best teams aren’t necessarily composed of the most “brilliant” individuals; they are the ones where people aren’t afraid to speak up.

When people feel safe, intelligence stops being an individual asset.

It becomes collective.”

 -Project Aristotle-

The key factor identified by Google’s research was psychological safety: the shared belief that the team is a safe space to speak up, ask questions, and even make mistakes without fear of humiliation.

This discovery has profound implications for organizational psychology. A team doesn’t perform better simply because its members are smart or competent. It thrives when the relational environment allows collective intelligence to emerge.

Conversely, when a culture is dominated by a fear of judgment or sarcasm, the opposite happens: people stop proposing ideas, avoid flagging problems, and pivot toward self-protection.

How to build healthy teams

In many organizations, there are individuals who use sarcasm, contempt, or condescension to systematically make others feel inferior. This isn’t always overt aggression; often, it’s a matter of “inside jokes,” snide remarks, or an air of superiority that creates a toxic climate over time.

This isn’t just an ethical issue: it’s an organizational failure. When humiliating behavior is tolerated, team members quickly learn that speaking up is a risk. They choose silence. And when people stop talking, the team loses its most vital resource: its ability to think together.

To address this, organizations must take concrete action:

• Identify toxic behaviors: Pay close attention to team dynamics. Look out for “weaponized” sarcasm, belittling jokes, or dismissive attitudes.
• Intervene immediately: Do not ignore “minor” microaggressions, even when they come from top performers. Tolerance only reinforces the fear of exposure.
• Provide constructive feedback: Ensure feedback focuses strictly on behaviors and ideas, never on the individual’s character.
• Foster psychological safety: Actively encourage “dumb” questions, diverse suggestions, and open post-mortems on mistakes.
• Lead by example: Leaders must set the standard for respect and active listening. Their behavior becomes the blueprint for the company culture.

Building healthy teams doesn’t mean avoiding conflict or lowering standards. It means creating an environment where the clash of ideas can be intense precisely because it is never an attack on a person’s dignity. Organizations that succeed in this regard gain an often underestimated advantage: people talk, ask questions, report errors, and suggest solutions.

Conclusion

In the modern workplace, the quality of relationships is the ultimate performance lever.

The lesson is simple yet transformative: the best teams aren’t the ones without conflict. They are the ones where no one is afraid to be heard.
