Why smart, well-intentioned people still make bad group decisions

Abstract image showing how smart people can make bad decisions

There is a particular kind of failure that doesn’t announce itself as failure until long after the damage is done.

The people involved are smart. The intentions are good. The information available at the time supported the decision. And yet, years — sometimes only months — later, everyone involved looks back and wonders how a room full of capable people made bad decisions that none of them would choose if they could do it again.

The answer is rarely incompetence. It’s structure.

Decisions don’t happen in a vacuum. They happen within systems — legal, organizational, social — that have their own logic, incentives, and momentum. Those systems shape outcomes as much as judgment does. Often more. And most people don’t see the structural problems until they’re already living with the consequences.

This pattern shows up differently depending on where you sit, but the mechanics are consistent. A decision that looks reasonable at each stage accumulates risk over time. Responsibility diffuses across people and roles until nobody owns the question “should we still be doing this?” Incentives misalign in ways that are obvious in hindsight and invisible in the moment. The loudest voice wins by default. And the consequences fall on whoever is left in the room.

What follows isn’t about pointing fingers. It’s about recognizing the structural forces at play before they decide for you. The same forces that determine whether trust survives under pressure — or gets spent all at once.

For boards and volunteer stewards

Volunteer boards face a structural problem that few organizations acknowledge: decisions don’t reset with each new board. They inherit.

When a board makes a significant decision, particularly one that will take years to resolve, the people who made that decision are rarely the ones still sitting in the room when the consequences fully materialize. Terms end. People rotate off. New members arrive with no emotional stake in what came before, but full responsibility for seeing it through.

That creates a dynamic where momentum substitutes for judgment. The question shifts from “Is this still the right decision?” to “Do we give up on what everyone before us committed to?”

Those are not the same question. But they feel the same in the room.

Sunk cost momentum without decision points

Consider a condominium board that discovers, shortly after taking control from the developer, that critical documents are missing, promised improvements were never completed, and operating budgets were misrepresented during the sales process. They engage an attorney. The attorney uncovers additional issues. The board, acting on legal advice and with broad owner support, decides to pursue litigation for damages.

That decision, when a prior board made it, was reasonable. The harm is real. The case has merit. The owners expect accountability.

What the board doesn’t do — and what almost no board in this position does — is establish clear, documented criteria for re-evaluation. Specific decision points. Pre-committed thresholds that would trigger a formal review of whether continuing is still worth the cost.

Instead, the litigation proceeds. Demand letters are ignored. Discovery drags. Years pass. Legal fees accumulate. The board that filed the lawsuit is no longer the board managing it. New members inherit a decision they didn’t make, along with the political and financial pressure to see it through. Owners who were angry at the developer five years ago are now angry at the board for spending so much money on attorneys.

The incentive structure has quietly shifted. What began as “hold the developer accountable” becomes “we’ve spent too much to walk away now.” Sunk cost logic — the very thing every board member would recognize as irrational in theory — becomes the operating principle in practice.

This is what behavioral researchers call escalation of commitment. The documented tendency for organizations to compound failing decisions rather than reverse them, especially when accountability is shared across many people.

The structural problem isn’t that the decision was wrong. It’s that there was no mechanism to force re-evaluation before exhaustion, cost, and momentum made the decision irreversible.

Diffusion of responsibility across time and roles

Social psychologists call this diffusion of responsibility — the more people present, the less any individual feels personally accountable. It was originally documented in emergency situations. It operates identically in boardrooms.In long-running decisions like litigation, governance transitions, or capital projects that span multiple years, responsibility diffuses to the point that accountability becomes nearly impossible.

No single board feels they have the standing to reverse a decision made by the collective “we.” The advisory committee meant to provide oversight becomes air cover rather than a forcing mechanism for hard questions. The one person willing to name the problem — often someone with a history of skepticism — gets dismissed as difficult rather than heard as a canary.

And so the decision continues. Not because each successive board actively chooses it, but because reversing it would require admitting that everyone who came before got it wrong. That’s not a judgment call. It’s a political impossibility.

What would have worked

The guardrail isn’t theoretical governance wisdom. It’s a documented decision framework established at the outset.

If demand letters are ignored for 12 months, the board formally reconvenes to assess whether litigation remains viable. If legal costs exceed a specific threshold relative to potential recovery, a community-wide review is triggered. If discovery reveals that key documents were destroyed, the board evaluates whether proceeding without that evidence still serves the association’s interests.

These criteria feel excessive when you’re starting. Paranoid, even. Defeatist.

They are none of those things. They are the structural safeguard that prevents momentum from substituting for judgment. They create decision points before the question becomes “Do we admit defeat?” rather than “Does this still meet the criteria we set?”

Most boards don’t establish them. And most boards, as a result, end up managing decisions they inherited rather than decisions they would choose.

For executives and the organizations they lead

Corporate environments have a different structural problem: misaligned incentives baked directly into organizational design.

A Chief Operating Officer is measured on stability. Reliable systems. Predictable outcomes. Their job is to keep the lights on and prevent operational surprises.

A Chief Strategy Officer is measured on transformation. New markets. Disruptive initiatives. Their job is to identify opportunities that require breaking the current system to build the next one.

Put them in a room together to make a decision, and the outcome is often determined not by what’s right for the business but by who has more organizational capital, who speaks with more authority, or who is willing to fight longer.

That is a structural conflict, not a personality conflict. And it predictably produces bad outcomes when the organization treats it as a collaboration problem rather than an incentive design problem.

When louder voices win by default

In most executive teams, there are always voices that carry more weight, people whose track record commands deference or whose communication style simply dominates the room.

There are also quieter, often more thoughtful voices. People who see the risk early, name it tentatively, yet defer when the pushback comes. Not because they were wrong. Because the cost of pushing wasn’t worth it.

A product manager raises concerns about data security during a roadmap review, gets firmly overruled by the VP pushing for faster feature delivery, and stops objecting. The issue doesn’t go away,  it just stops being discussed.

The group interprets their silence as agreement. It isn’t. It’s exhaustion. Or self-preservation. Or a well-founded belief that challenging the louder voice will mark them as uncooperative or not a team player.

Over time, those quieter voices stop speaking up at all. The dissent that could have prevented a bad decision disappears. And the organization loses the very signal it needed most.

Irving Janis, whose research on groupthink remains the foundational study on collective decision failure, found that dissent doesn’t disappear because people stop noticing problems. It disappears because the cost of naming them becomes too high.

What breaks the pattern

Standing debriefs where decisions are regularly reviewed. Role clarity that names conflicts instead of pretending they don’t exist. Processes that force dissent into the open rather than letting it die quietly in the hallway after the meeting ends.

These aren’t soft interventions. They are structural ones. And they work not by changing people’s judgment, but by changing the conditions under which that judgment operates.

For job seekers navigating a transition

Job seekers don’t usually make group decisions. But they operate inside a structure that produces the same dynamic: too many voices, no clear framework for filtering them, and a final decision that represents no coherent point of view.

Everyone has advice. Former colleagues think you should emphasize leadership. Your mentor says to focus on technical capabilities and depth. The outplacement consultant wants you to lead with metrics. A well-meaning friend insists you’re underselling your creativity. LinkedIn thought leaders have 17 conflicting opinions, all delivered with confidence.

The stakes feel existential. So instead of filtering the advice, you try to incorporate it all. The result is a self-presentation that sounds like a committee wrote it. Technically accurate. Humanly absent. A Frankenstein narrative that represents no recognizable person.

Advice paralysis and self-abandonment

The structural problem is this: job seekers operate in a high-vulnerability situation where everyone feels entitled to weigh in. And because the stakes are real — rent, identity, confidence — candidates defer to volume rather than relevance.

They collect opinions. They weigh all voices equally. And then they either freeze, unable to reconcile the conflicts, or produce something that tries to please everyone and convinces no one.

That paralysis is diffusion of responsibility (see Board Consulting section above) in a different form. Instead of spreading accountability across a board or a team, it spreads across every person who offered input. Either way, they’ve abandoned the one source of judgment that actually differentiates them: their own.

When self-awareness becomes the structure

The antidote is not ignoring advice. It’s curating it.

That requires knowing yourself well enough to recognize which input fits and which doesn’t. To have a reason for taking advice that’s as clear as your reason for dismissing it. To understand that being authentic doesn’t mean rejecting all external input; it means filtering that input through a coherent sense of self.

That’s not intuition. It’s structure. A decision-making framework that treats advice as input rather than direction, and recognizes that ultimately, the presentation either represents you or it doesn’t.

Without that framework, the job seeker is just another group making a bad decision. Except that the group is imaginary, and the person paying the price is very real.

What these situations share

The board stuck in a decade of litigation. The executive team where the loudest voice wins. The job seeker whose presentation sounds like everyone except themselves.

None of these failures comes from a lack of intelligence. They come from operating within systems that have their own momentum, blind spots, and structural incentives. Systems designed around entirely different priorities.

You can’t opt out of those systems. But you can build guardrails.

Pre-committed decision points that force re-evaluation before momentum substitutes for judgment. Role clarity that names conflicts instead of pretending they don’t exist. Processes that surface dissent instead of allowing it to die quietly. Frameworks that help individuals filter input rather than deferring to volume.

These aren’t soft interventions. They’re structural ones.

And they work not by making people smarter or better-intentioned — most people already are — but by changing the conditions under which judgment operates.

The question is not whether smart, well-intentioned people can make bad decisions.

They can. They do. Regularly.

The question is whether the structure around them makes those bad decisions harder to sustain. Or easier to inherit, defend, and repeat until the damage is undeniable.

If this resonates, the work we do — across board consulting, executive coaching, and strategic communications — starts with this same foundation. Schedule a conversation.
