Adam Grant, one of my most recommended authors, wrote an opinion piece for the New York Times in which he states, “One of the tragedies of the human condition is that we use our big brains not to make rational decisions but rather to rationalize the decisions we’ve already made.” It’s a line that lands with the kind of sobering clarity Grant is known for, and it speaks to a fundamental flaw in how we humans make decisions. Instead of approaching new information with objectivity, we often look for ways to reinforce the beliefs and choices we already hold. This pattern, known as the escalation of commitment, has far-reaching implications, from how we manage products and people to how we lead organizations and evaluate risk.
Over the past few years, this topic has been explored under many banners: confirmation bias, the overconfidence effect, and commitment bias tied to the sunk cost fallacy. While each term has its own nuance, they all orbit a central truth, that humans are wired to resist changing our minds. And possibly for good reason. From an evolutionary standpoint, trusting the consensus of your community was adaptive. Most of what our ancestors knew to be true came not from direct observation but from what others told them. As such, skepticism of outliers or dissenters helped preserve shared knowledge, and thus survival.
But what was once useful for survival can become counterproductive in today’s environment of rapid change, information overload, and complex problem-solving. The cost of clinging to outdated ideas isn't just intellectual stubbornness, it’s slower innovation, strained relationships, bad decisions, and lack of accountability. In the world of product development, for example, we’ve all seen teams invest deeply in a solution long after evidence suggests it’s not working, simply because to pivot would feel like admitting defeat.
So what’s the remedy? Grant and others propose a simple yet profound solution: build a challenge network. Think of it as the opposite of an echo chamber. Rather than surrounding ourselves with cheerleaders who validate our every move, we need thoughtful critics, people who care enough to push back. These are colleagues, mentors, or friends who are willing to question assumptions, highlight blind spots, and challenge us to do better. They aren’t adversaries; they’re intellectual allies who help us hold ourselves to higher standards.
In my experience, challenge networks aren’t just useful, they’re essential, especially as your expertise grows and you are surrounded by fewer people who feel empowered to challenge you directly. They force us to pause, rethink, and, when necessary, change course. Especially for leaders, who often operate in environments where power dynamics discourage dissent, cultivating a challenge network is one of the most important forms of professional hygiene. It keeps us humble. It keeps us honest. And perhaps most importantly, it keeps us growing.
How Challenge Networks Work in Practice
It’s one thing to talk about the concept of a challenge network, it’s another to live it. The value of these networks lies not in theory, but in the messy, sometimes uncomfortable, often transformative practice of being told you're wrong, and then being grateful for it.
Here are three real-world examples, anonymized, that illustrate how challenge networks can take shape, and why they’re so powerful:
1. The CTO Who Invited Discomfort, Biweekly
A former colleague of mine has been working closely with a CTO at a fast-scaling tech company. Alongside another advisor, they’ve formed what the CTO refers to as his personal “challenge network.” Every two weeks, for more than 16 months now, they sit down with him to dissect decisions, question priorities, and flag areas where things feel off-track.
The structure is focused but flexible: four annual goals serve as the north star, supplemented by real-time feedback the CTO receives from his CEO. What makes these sessions unique is how intentionally uncomfortable they are. The CTO doesn’t just tolerate critique, he seeks it out. Some of the feedback has been direct and hard to swallow, but he consistently says it’s one of the most valuable meetings he has. Why? Because no one else around him is pushing back. This forum gives him exactly what most senior leaders lack: an honest mirror.
2. The Unwelcome (But Spot-On) Consensus
Another friend, a product leader at a mid-sized tech firm, recently reached out to her network of experienced CTOs to pressure-test a strategic plan. She met with five people, each from different companies, with different backgrounds, expecting a range of input. Instead, she got a wall of consistency. All five pointed to the same blind spot in her recommendations.
It wasn’t what she wanted to hear, and it initially stung. But after sitting with it, she realized they were right. They had all picked up on a higher-level issue she had overlooked, one that had big implications for her roadmap. That clarity, painful as it was, helped her avoid a misstep, and reminded her of the power of surrounding yourself with people who aren't afraid to challenge your thinking.
3. The Accidental AI Critic
One engineering director I know has started using generative AI tools as part of her personal challenge network. When reviewing strategy docs or internal write-ups, she’ll often run a prompt like, “What’s wrong or missing from this list?” through an AI assistant. She’s even tested one GenAI model’s work by feeding it to a second model for critique.
It’s not perfect, AI can’t replace the insight of a seasoned peer, but she’s found that it often surfaces surprising gaps. Things like unspoken assumptions, narrow framing, or missing alternatives. It’s a lightweight way to catch early flaws before exposing the work to a broader audience. She jokes that it might be her “AI challenge network”, not a replacement for human feedback, but a helpful sparring partner nonetheless.
Why This Matters
These examples all highlight the same underlying truth: we can’t see our own blind spots. No matter how smart, experienced, or self-aware we are, we’re still operating from a limited vantage point, shaped by our experiences, assumptions, and incentives. Challenge networks expand that field of vision.
But they also require something of us: vulnerability. It’s not easy to invite critical feedback, let alone absorb it without defensiveness. Especially in leadership roles, where the pressure to appear confident and decisive can make dissent feel threatening.
That’s why the best leaders don’t just tolerate challenge networks, they actively cultivate them. They structure time for feedback. They seek out perspectives beyond their immediate teams. They create environments where “I think you’re wrong” isn’t seen as insubordination but as a sign of engagement.
How to Build Your Own Challenge Network
The idea of a challenge network sounds great on paper, but what does it look like in practice? Who should be part of it, how do you structure it, and how do you ensure it’s actually useful (and not just another meeting with feedback theater)?
1. Choose Thoughtful Critics, Not Just Smart People
The first step is selecting the right people. You’re not just looking for “the smartest folks in the room”, you’re looking for the people who are both willing and able to challenge you constructively. That means:
Independence: They shouldn’t be too entangled in your world (e.g., direct reports), or too concerned with protecting your ego.
Contextual Awareness: They should understand enough about your domain to offer relevant critique, but not be so deep in the weeds that they share all your assumptions.
Courage and Care: The best challenge network members are the ones who can tell you hard truths because they want you to get better, not because they want to be right.
Think of them as your intellectual personal trainers, there to push you, not placate you.
2. Set the Frame Explicitly
Don’t assume people know you want tough feedback, say it out loud. Better yet, write it down.
Tell them:
“My goal here is to stress-test my thinking. I don’t need validation, I need you to point out what’s wrong, what I’m missing, or what I might be overconfident about.”
Bonus points if you give them context for your goals (like the CTO example earlier) so they know what success actually looks like. This helps them tailor their critiques to your intent, not just nitpick tactics.
3. Make It a Habit, Not a Hail Mary
A challenge network isn’t just something you call in a crisis or use once a quarter. The best results come from repeated exposure over time. That’s when you build trust, shared vocabulary, and a deeper understanding of your goals and blind spots.
This doesn’t mean you need a weekly standing meeting. But you should have a cadence. For example:
A biweekly review with a small, trusted group.
A monthly rotation of different perspectives on new initiatives.
A pre-launch ritual before major decisions, “Run this by two members of your challenge network before signing off.”
Repetition builds rhythm. And rhythm builds trust.
4. Ask Better Questions
The fastest way to deepen the value of your challenge network is to ask better questions. Instead of “What do you think?”, try:
“What’s most likely to go wrong here?”
“What am I underestimating?”
“Where might I be bullshitting myself?”
“What would make you uncomfortable if you were in my shoes?”
Or, in the style of my favorite GenAI prompt:
“What’s wrong or missing from this plan?”
Questions like these open the door to real critique, not just polite commentary.
5. Make Feedback Actionable (and Track It)
If you’ve asked for critical feedback and done nothing with it, don’t be surprised when it dries up. People stop giving real input when they believe it vanishes into the ether.
Instead:
Summarize what you heard.
Let them know what you’re going to act on, and what you’re choosing not to, and why.
Circle back later and share the results.
This reinforces that the input mattered, and that you’re not just collecting critique for the sake of performance, but to improve outcomes.
The Leadership Advantage
For leaders, a challenge network is more than a tool, it’s a moat. It protects against arrogance, isolation, and inertia. In high-growth companies especially, success can be dangerous: it breeds overconfidence and insulates decision-makers from honest feedback.
The most effective leaders I’ve worked with aren’t just open to challenge, they design for it. They build the muscles and the mechanisms to invite dissent, revisit decisions, and elevate their thinking.
In an environment where speed and certainty are often prized above reflection, the willingness to be wrong, and to surround yourself with people who will tell you you’re wrong, might be the most underrated competitive advantage there is.
Conclusion
In a world that rewards certainty, it's easy to mistake confidence for competence, and to mistake agreement for alignment. But real leadership isn't about having all the answers. It’s about creating the conditions where better answers can emerge, even if that means being challenged, corrected, or completely wrong.
Challenge networks don’t just improve decision-making, they improve leaders. They keep us humble. They keep us curious. And most importantly, they keep us from drifting into our own echo chambers of logic and self-justification.
Whether your network is made up of trusted colleagues, former mentors, sharp peers, or even a carefully tuned AI model, the goal is the same: pressure-test your thinking before the world does it for you. And here's the truth: if you don’t build a challenge network, reality will eventually become one. And reality is rarely as kind.
Call to Action
If you’ve made it this far, ask yourself:
Who do I trust to tell me when I’m off track?
When’s the last time someone made me rethink a strongly held belief?
Have I built systems for feedback, or am I just hoping it finds me?
If you don’t yet have a challenge network, now’s the time to build one. Start small. Reach out to someone whose perspective you respect, and invite critique with intention. If you already have one, give it more structure, more frequency, or a more explicit frame. Don’t wait for a crisis to find out whether your ideas can hold up under scrutiny.
And if you’re a leader: model this behavior. Let your teams see that critical feedback isn’t a threat, it’s a tool. When challenge becomes part of the culture, growth becomes the norm.
Really love this one, thank you.
Love the idea of a challenge network. Peer networks can help you see so clearly what’s missing in front of your eyes. Thanks for sharing!
