Shared Brain: Getting in Sync

What the research shows: ‍

‍

When teams feel off, it’s rarely about capability—it’s about alignment. Shared Mental Models allow teams to stay coordinated by aligning how they see the work and each other.

A Shared Brain: The Team Feels Out of Sync 

‍

Ever been in a team where everyone is capable… but things just don’t click?

Deadlines slip. Conversations feel clunky. People hesitate or duplicate work.

Most leaders assume it’s a skills issue.

Research suggests otherwise.

Studies of high-pressure teams—like fighter pilots in simulated combat—show that failure is rarely about talent. It’s about something less visible: how aligned people are in their understanding of what’s going on.

‍

The Missing Piece: Shared Mental Models

‍

In one of the foundational research streams in team performance (e.g. Cannon-Bowers, Salas & Converse, 1993; Mathieu et al., 2000), this alignment is called a Shared Mental Model (SMM).

In plain English:

It’s the internal map people use to understand the situation, how things work, and what’s likely to happen next.

These models allow teams to:

• Describe what’s happening
• Explain why it’s happening
• Predict what will happen next

That last part—prediction—is what separates average teams from high-performing ones.

‍

Teams Run on Two Tracks (And Most Ignore One)

‍

The research is clear: effective teams don’t just share an understanding of the task.

They share an understanding of each other.

Cannon-Bowers et al. (1993) distinguish between two types of mental models:

‍

1. Taskwork Models

‍

• Tools and systems
• Processes and plans
• Likely scenarios and contingencies
  ‍

2. Teamwork Models

‍

• Roles and responsibilities
• Communication patterns
• Individual strengths, habits, and tendencies

Most teams focus heavily on the first.

The evidence suggests the second is just as—if not more—important.

‍

Why Understanding Each Other Drives Performance

‍

Mathieu et al. (2000) found that team-based mental models have a strong impact on how teams actually function day to day.

Why?

Because they allow people to tailor their behaviour.

When you understand your teammates:

• You anticipate what they need
  
  
• You adjust how you communicate
  
  
• You avoid unnecessary back-and-forth
  
  

This reduces what researchers call “process loss”—the wasted effort that comes from poor coordination.

‍

The Real Test: What Happens Under Pressure

‍

Here’s where this really matters.

In high-pressure situations—like the F-16 simulations used in research—teams don’t have time to constantly talk things through.

And that’s exactly where Shared Mental Models prove their value.

As Mathieu et al. (2000) put it:

‍

_{“Shared mental models become crucial… because they allow members to predict the information and resource requirements of their teammates.”}

‍

In other words:

👉 The best teams don’t just communicate well
👉 They need less communication in the first place

Because they already know what’s coming.

‍

Why Alignment Alone Doesn’t Improve Performance

‍

There’s an important nuance in the research that most people miss.

Shared understanding doesn’t directly improve results.

It works through behaviour.

This is captured in the well-established Input–Process–Outcome (I-P-O) model (Hackman, 1987; McGrath, 1984):

• Input → Shared mental models
• Process → Coordination, communication, cooperation
• Outcome → Performance

If shared understanding doesn’t improve how a team:

• Coordinates
• Communicates
• Works together

…then it won’t improve results.

You can be “aligned” and still ineffective.

‍

The Biggest Myth: Teams Don’t “Just Gel”

‍

One of the most useful findings from Mathieu et al. (2000) is this:

Teams do not naturally develop shared mental models just by working together.

In their study:

• Teams received performance scores (outcome feedback)
• But no structured reflection or guidance

Result?

👉 No meaningful alignment over time

The conclusion is blunt:

“Time on task alone is not enough.”

Without structured reflection—like After Action Reviews—teams simply repeat the same patterns.

‍

A Critical Warning: You Can Be Aligned and Still Wrong

‍

Another key insight from the research:

Shared ≠ Correct

Teams can have:

• High agreement
• Strong confidence
• Complete alignment

…and still perform poorly.

Why? Because they’re aligned around an inaccurate model.

This is why some researchers distinguish between:

• Convergence (are we aligned?)
• Quality (are we right?)

You need both.

‍

What This Means in Practice

‍

If your team feels out of sync, the fix isn’t more effort.

It’s better alignment—deliberately built.

Based on the research, focus on three things:

‍

1. Align on the task

‍

• Goals
• Plan
• Constraints

‍

2. Align on the team

‍

• Roles
• Communication norms
• Individual tendencies

‍

3. Build alignment actively (not passively)

‍

• Use After Action Reviews
• Reflect on how work gets done
• Make assumptions explicit
  
  

‍

The Bottom Line

‍

High-performing teams don’t just share information.

They share understanding.

And more importantly, they share the right understanding.

As decades of research shows, the real driver of performance isn’t individual talent.

It’s the alignment of how people think about the work—and each other.
