Success Depends on Psychological Safety

I just came back from a trip to my old campus, MIT in Cambridge.
I learned something.

Imagine assembling a team of the brightest minds in the world. Success seems inevitable, right? Not necessarily.
MIT researchers studying team performance made a surprising discovery: how a team works together matters more than who is on the team. In other words, a group of geniuses doesn’t automatically equal a genius team.

So, what makes a team truly thrive? The answer lies in psychological safety.
Psychological safety is the belief that you can share ideas, ask questions, and admit mistakes without fear of ridicule or retribution. It’s the invisible thread that turns a collection of individuals into a cohesive and innovative team.

Here’s why it matters:
Encourages Open Communication
↳ Teams thrive when members feel safe to speak their minds.
↳ Open communication sparks creativity and allows innovative ideas to emerge.

Fosters Collaboration
↳ When people trust one another, they’re more likely to collaborate freely and share knowledge.
↳ This trust strengthens relationships and accelerates problem-solving.

Reduces Fear of Failure
↳ In psychologically safe environments, mistakes are seen as opportunities to learn, not as career-ending disasters.
↳ This mindset encourages experimentation, which is critical for growth.

Leverages Diversity
↳ Diverse teams are powerful, but only if every voice is heard.
↳ Psychological safety ensures that different perspectives are valued, driving better decisions and outcomes.


MIT’s research underscores a crucial point:
What matters most isn’t the credentials or IQ of the team members, but how they interact and create a safe space for each other.

It’s about listening as much as speaking. It’s about respect and empathy. And it’s about creating a culture where everyone feels empowered to contribute.

Think about your own teams:
→ Are you fostering an environment where people feel safe to share their ideas?
→ Or are brilliant minds holding back because they fear judgment?

The secret to success isn’t just in the talent you gather—it’s in the culture you build.

Let’s create teams where everyone can thrive.

Key Findings from MIT Research

1. Collective Intelligence Over Individual IQ: A significant study co-authored by MIT researchers Thomas Malone and Anita Williams Woolley demonstrated that groups possess a form of collective intelligence that is distinct from the sum of their individual IQs. This collective intelligence significantly predicts a group’s performance across various tasks, accounting for about 40% of the variation in performance. The study found that simply grouping highly intelligent individuals does not guarantee high group performance.

2. Role of Gender Diversity: The same research indicated that teams with a higher proportion of women tended to perform better. This was attributed to women’s generally higher social intelligence, which enhances group dynamics and cooperation.

3. Psychological Safety: Google’s extensive study on team effectiveness, known as Project Aristotle, corroborated these findings by revealing that psychological safety—where team members feel safe to take risks and express their ideas—was the most crucial factor for high-performing teams. Teams characterized by this safety were more likely to harness diverse ideas and be rated as effective by executives.

4. Communication Dynamics: Further studies highlighted that effective communication within teams is vital. Teams that balance exploration of new ideas with focused task engagement tend to outperform others. Emotional intelligence among team members also plays a crucial role in fostering a collaborative environment.

5. Implications for Team Formation: The overarching conclusion from these studies is that organizations should focus on creating environments where collaboration thrives rather than merely assembling groups based on individual accolades or intelligence. This understanding can help avoid common pitfalls in team formation, where the assumption is made that high IQ alone will lead to success.

These insights suggest that fostering strong interpersonal relationships and a culture of open communication is essential for maximizing team performance, reinforcing the idea that “how” a team works together is paramount to its success.
