The Antifragile Leader’s Guide to the Default Mode Network

A plain-English recap of the takeaways, or why your brain’s inner narrator matters for leadership
Well that didn’t go very well! Since it’s impossible to read the room on LinkedIn, I continued to write about the default mode network despite low engagement. Late summer, I thought to myself, kids are home from camp and not back at school yet – the hard part for all the working parents out there! The record-breaking heat wave in the Carolinas in late June and the whole of July broke and glorious August broke out in the Blue Ridge – cooler nights, crisper mornings, and perfect working days (anything below 100°F real-feel qualifies). In this environment, I was much more focused on getting outside to tend and mend the gardens and the woods and to catch up on projects delayed by the heat.
Then I reached out to one of my most treasured readers, an old colleague from Wall Street who is probably the best banker I’ve ever met. He’s a real leader, living the challenge from client to client, deal to deal, season to season, year to year, a leader not just in the office where he manages one of the top producing teams, but working on national projects and as a thought leader in his industry. He’s no stranger to the life difficulties that can interpose themselves in our brains between our best self and our work. I asked him what he thought about the series – was it just a late summer phenomenon, or had I gone overboard on the neuroscience?
And this is how you know we are real friends, not temporary, transactional allies. His response was that yep – I whiffed. I missed the mark. I missed the fundamental ask that every banking pitch has to offer to the client: What’s in it for me? We used to call this the WIFM (pronounces “whiff-um” – PERFECT!). Why should the client care? What difference will it make for them? So, this wrap up is my attempt to cover the same material in plain English, with WIFMs.
The Problem:
Leaders get stuck in their own heads.
Overthinking.
Self-doubt.
Repeating old patterns.
Struggling to be present with people.
Missing key emotional signals.
Defaulting to action when reflection is needed—and vice versa.
What’s Really Going On?
You have a brain network active behind the scenes, constantly narrating your life.
It’s called the Default Mode Network (DMN).
It kicks in when your mind wanders—thinking about yourself, others, the past, the future.
It’s where your internal story gets written. And that story shapes your relationships and how you lead.
Why It Matters for Leadership
Challenge: rumination / overthinking.
The DMN loops old stories. You can use short pauses to reset focus.
Challenge: impostor syndrome / doubt.
The DMN replays the self-critique. You can reframe the inner voice with compassion.
Challenge: disconnection from others.
The DMN obsessively self-references. You can shift to social DMN mode: get curious.
Challenge: inflexibility under pressure
The DMN clings to old identity. You can rewrite your story through reflection and embodiment.
Challenge: decision paralysis
The DMN gets stuck in hypotheticals. You can interrupt with a breath and move to action.
Tools We Explored
The Strategic Pause
→ A breath or moment of stillness that helps your brain shift from autopilot to awareness. WFIM: now that you’ve fully engaged your pre-frontal cortex, you have access to novel solutions that your fast and neurologically frugal autopilot will never let you anywhere near. It takes more calories to do this slow work, but it can be a place of serious creativity, more important than ever in these complex times.Bringing Curiosity Online
→ Asking “What else might be true?” or “What am I not seeing yet?” to disrupt looping thought patterns and open new perspectives. WIFM: Curiosity shifts you from tunnel vision to wider possibility. This subtle neural shift turns off fear-based reactivity and re-engages the salience network—the brain’s switchboard for relevance. The result? Better options, fewer blind spots, and decisions that reflect the full complexity of the moment.Narrative Awareness
→ Asking, “What’s the story I’m telling myself?” and deciding if you still believe it. WIFM: When you recognize that your self-talk is a constructed narrative—not a fact—you gain power to edit it. This boosts emotional agility and helps you stop spinning in doubt, fear, or old scripts that no longer serve your leadership.Social Connection
→ Learning to “read the room” through body cues, breath, and shared presence. WIFM: The better you tune in to others' unspoken signals, the more trust you build. This creates psychological safety, strengthens your leadership presence, and enables faster, more cohesive decision-making across your team, even or perhaps especially in challenging times.Rewriting the Story
→ Using questions, embodiment, and forward-looking reflection to re-author your leadership identity. WIFM: In times of disruption, you can’t always control events—but you can reframe how you make meaning of them. This is a skill of enhanced resilience that helps you pivot faster, lead through change with confidence, and model growth for others.
Bottom Line
If you’ve made it this far, here’s what we’ve learned: the Default Mode Network isn’t a villain—it’s your brain’s storyteller-in-chief. And like any good narrator, it needs an editor. The leaders I coach don’t just want better habits; they want a clearer path through complexity. That path starts by working with the DMN instead of getting hijacked by it. A moment of stillness—a strategic pause—helps interrupt autopilot so real creativity can emerge. Curiosity, when it’s online, turns fear into perspective and widens your field of vision. Asking, “What’s the story I’m telling myself?” helps reframe self-doubt as a narrative choice, not a truth. Reading the room becomes a muscle of social connection—one that builds trust far faster than words can. And finally, when disruption comes, as it always does, you can rewrite the story, not erase it—moving from setback to origin story, from derailment to redesign. These aren’t just brain tricks. They’re how we evolve. You don’t have to be perfect. But you can become more human, more present, and more antifragile than ever before.
