In November 1915, Ernest Shackleton watched his ship, the Endurance, sink into the Antarctic ice.
27 men. Minus twenty degrees. No radio. No rescue. The mission was over; survival was the only goal.
The next morning, Shackleton didn't give a speech. He served hot tea to his crew. Not because tea would save them, but because he knew what his men needed wasn't a plan—it was the feeling that someone was paying attention.
Over the next 16 months, Shackleton kept every single one of those men alive. Not by having the answers — he often didn't. But by doing something far harder: managing the emotional state of his team so they could think clearly enough to survive. He celebrated birthdays on the ice. He moved the biggest complainers into his own tent so their negativity wouldn't spread. He gave every man a defined role, no matter how small.
He didn't succeed by removing the danger. He did it by regulating it.
He operated in a state most leaders miss: The Productive Zone of Disequilibrium.
🧠 Why Uncertainty Breaks People & Teams
When people/teams face uncertainty, the amygdala (threat detection) often hijacks the brain. It redirects energy from the prefrontal cortex—the home of strategy and collaboration—to immediate survival systems.
Empathy narrows. Perspective-taking shuts down.
When an entire team enters this state, it’s no longer a team; it’s a collection of survival instincts in a conference room. People overfocus on self-interest, stop collaborating, hoard information, and stop challenging ideas.
While this survival mechanism imprinted in our brains was useful in the distant past—and remains helpful at times—it can be extremely detrimental today. This is especially true when uncertainty runs high, and our ability to survive depends on working together to solve complex problems.
This is what most leadership advice misses. It tells you to "communicate a clear vision" or "be transparent." Good advice, but it ignores the biology. You can't communicate your way past a hijacked nervous system. You have to address the anxiety first!
🔥 The Tool: The Zone of Productive Disequilibrium
Harvard professor Ronald Heifetz identified that when teams face adaptive challenges that produce high uncertainty, they land in one of three zones. Your first job is to know where you are:
🥶 The Work Avoidance Zone (Too Cool)
Teams sweep problems under the rug. Everyone maintains a polite, fake peace. The problem grows quietly until it explodes.
🥵 The Panic Zone (Too Hot)
People feel unsafe and overwhelmed. They freeze, burn out, fight, blame, quit. No learning happens here—only damage.
⚡ The Productive Zone (Just Right)
The sweet spot. There is enough tension to demand attention, but enough safety to think. Opposing views surface. The urgency is real, but not paralyzing.
Shackleton was a master of this zone. He raised the heat when complacency crept in, and lowered it when spirits broke. He wasn't just a captain; he was a thermostat.

🪞 How to Be the Thermostat
Effective leaders don't just "resolve" conflict; they regulate the temperature to keep the team in the Productive Zone.
Rising the Heat
You raise the heat when complacency has set in, when people are protecting a false peace, or when the cost of inaction is growing invisibly:
Ask the "What If" Nobody Wants to Voice - Drop a single, high-stakes question like, "What if our pilot fails and we lose the funding stream?" Curiosity licenses the group to confront risks they’ve been avoiding.
Map Divergent Opinions - Don't let people agree too quickly. Volunteer to capture viewpoints on a whiteboard and place conflicting ideas side-by-side. Visualizing tension makes contradictions undeniable and invites necessary debate.
Share a Fresh Outside Example - Briefly recount how a comparable team elsewhere solved (or failed at) a similar challenge. External contrast jolts colleagues out of local complacency.
Float a Bold, "Half-Baked" Idea - Preface with "This might be off-the-wall, but…" and propose a stretch solution. Your vulnerability signals permission for others to think bigger, raising the collective stakes.
Highlight Imminent External Deadlines - Casually remind the room, "Our competitor’s launch is eight weeks away." A simple time-pressure reminder often sparks the necessary urgency.
Lowering the Heat
You lower the heat when people are frozen, when meetings have gone silent, when the team is burning out, or when panic is setting in:
Name the Emotional Undercurrent - Gently mirror what you sense—"I’m picking up some frustration; does that resonate with others?" Acknowledgment alone often diffuses tension because people feel seen.
Propose Silent Reflection- When arguments heat up, say, "Could we each jot thoughts for three minutes before debating?" The quiet space lowers reactivity without needing official approval or a "calm down" command.
Summarize Points of Agreement: Jump in with, "Sounds like we all care about user impact and timeline—did I miss anything?" Reminding the group of shared ground cools polarity immediately.
Chunk the Problem: When the team is overwhelmed, volunteer to draft a step-by-step outline. Converting a big, blurry challenge into discrete tasks reduces overwhelm and gives the brain a "handle" on the problem.
Inject a Moment of Lightness: When the room feels tight, offer a brief, self-deprecating joke or a story. "Remember when our last launch crashed five minutes before go-live—and we still pulled it off?" Appropriate humor releases tension physically and signals it’s safe to breathe.
✅ Your Action for This Week
In your next meeting, your first move is to observe and read the room - what is the current temperature in the meeting? Where is the team? In which part of the zone? Or do you notice yourself or a particular team member is outside of the Productive one?
Before you make an intervention, you want to make sure that you sharpen your diagnostic skills. Then you can decide to intervene if there is a disequilibrium (rise or reduce the heat).
But also notice what your state is? You, just as anyother team member, can be in different states compared to the rest of the team.
You first regulate yourself, then others!
History remembers Shackleton as a great explorer, but his men remembered him as the guy who made the tea.
He didn't have a rescue plan. He didn't have a map home. He had a tent, a stove, and the wisdom to know that before his men could survive the ice, they had to survive their own minds.
Leadership in uncertainty isn’t usually about the "Braveheart" speech at the front of the room. It is the quiet work at the back of the room. It is noticing the silence. It is sensing the fear. It is the courage to be the thermostat that regulates the pressure, so your team doesn’t crack.
The ice is always going to be there. The question is: Will you let it freeze your team, or will you be the one who keeps the fire lit?
Until next time, keep evolving ✊
