Connectedness: The Neuroscience of Why Leaders Must Share Power

Leadership has long been painted as a story of visionaries, bold individuals who steer the ship, set the course, and rally others to follow. But neuroscience tells us a different story: the decisions we make are inherently social. The brain is not a solitary organ. It evolved to function within networks, to predict and adapt to the behaviors of others, and to survive by embedding itself in groups.

This is why connectedness isn’t a “soft skill.” It’s the neural foundation of high-performing teams.

The Brain Craves Belonging

From a neurobiological standpoint, our brains treat social disconnection with the same alarm bells as physical pain. MRI studies have shown that social rejection activates the anterior cingulate cortex, the very region that lights up when we stub a toe or burn a finger. This means that when employees feel excluded, ignored, or powerless in decision-making, their brains literally register it as harm.

On the flip side, long-standing groups who develop deep connections trigger the release of oxytocin, dopamine, and endorphins, the neurochemicals of trust, reward, and vitality. These biochemical reinforcements make us more resilient to stress, more creative under pressure, and more willing to go the extra mile for the collective.

Simply put: connection isn’t just about feeling good. It’s about keeping brains online and teams performing at their peak.

Connection and Control Go Hand-in-Hand

But here’s the disruption most leaders miss: connection doesn’t happen by accident. It’s cultivated by shared power.

In a recent series of leadership interviews, multiple participants emphasized that their ability to maintain performance vitality required more than social support; it required a degree of control in shaping future outcomes. When employees feel they can influence decisions that affect their work, their brains shift out of defensive mode and into exploratory mode.

Neuroscience calls this a move from “threat state” to “reward state.” The amygdala (our threat detector) quiets down, while the prefrontal cortex (our executive decision center) comes online. This shift unlocks higher-order thinking, collaboration, and problem-solving, the very essence of performance vitality.

Leaders who hoard decision-making power not only fracture connectedness but also stunt the very brain functions their organizations rely on to adapt and thrive.

Why Long-Standing Groups Thrive

There’s a reason why long-standing groups tend to outperform newly assembled teams. Over time, they develop what social neuroscientists call relational schemas —mental models of how others are likely to behave. These schemas reduce uncertainty, increase trust, and speed up collective decision-making.

Think of it as the team’s shared neural network. Each member learns not only to rely on others but also to anticipate and complement their moves. In a fast-changing world, that interconnectedness is rocket fuel.

But this is fragile. Strip individuals of decision-making influence, and the system destabilizes. The brain reverts to self-preservation mode, silos harden, and collaboration erodes.

The Leader’s Role: Architect of Social Systems

If decisions are inherently social, then leaders must be architects of social systems, not just strategists. This means intentionally designing environments that maximize connectedness through shared ownership.

Here are three neuroleadership practices to make that real:

1. Distribute Decision-Making Power

Invite input where it matters most. Shared decision-making signals respect and reduces status threat—one of the brain’s most destabilizing triggers. Even small moves, like involving employees in how meetings are structured or how goals are prioritized, reinforce the sense of control that sustains vitality.

2. Reinforce Predictability and Fairness

Brains crave certainty. Leaders who communicate openly about how decisions are made (and follow through consistently) build trust at the neural level. The perception of fairness activates the striatum, our brain’s reward center, strengthening loyalty and motivation.

3. Foster Micro-Moments of Connection

Connectedness doesn’t come only from big retreats or town halls. It’s in the micro-moments: pausing to ask for someone’s perspective, recognizing effort in real time, or creating peer-to-peer decision forums. Each moment triggers a cascade of trust-building chemicals that, over time, become the foundation of a resilient culture.

Connectedness as a Strategic Advantage

In an era of AI, hybrid work, and constant disruption, leaders are obsessed with speed, efficiency, and data. But the paradox is apparent: the more complex our environment becomes, the more dependent we are on the simplicity of human connection.

Teams that feel connected and empowered don’t just perform better, they adapt faster. They innovate more boldly. They recover from setbacks more resiliently.

Connectedness isn’t “nice to have.” It’s the competitive edge. And the leaders who understand that decisions are inherently social, and that shared power is the key to vitality, will be the ones who thrive in the future of work.

Bottom line: The human brain was wired for connectedness long before it was wired for competition. Leaders who design for shared power don’t just create better teams, they activate the deepest neural advantage we have: our ability to rely on one another.
