Charlan Nemeth spent a career running experiments on dissent. Her work converges on an unsettling finding. The benefit of disagreement, she shows, depends on something I can’t manufacture on a dissenter’s behalf.
Anonymity can help surface authentically held minority views, but it solves only half the problem. What actually triggers the divergent thinking that makes dissent valuable, Nemeth argues, is conviction: a dissenter who genuinely believes a different position and is willing to say so, persistently, even under pressure. Anonymity obscures exactly this signal.
When a group cannot identify the source of a minority view, they cannot perceive the courage and consistency that compel genuine engagement with it. I’ve called this the “ghost in the room” — a disembodied position that haunts a conversation without the named, committed presence that Nemeth’s research suggests is required to make it matter. (I explored that haunting in an earlier essay; Nemeth’s framework gives it a second meaning.)1
What Nemeth Found
Let’s start with the part that’s easy for me to like, because it supports my point of view. Nemeth’s case, laid out in her book, In Defense of Troublemakers, is that dissent improves the quality of a group’s thinking, and that it does so regardless of whether the dissent is right.2 The minority voice helps because it breaks the gravitational pull of consensus and forces us to think differently. We search for more information, weigh more options, and consider the cons of our initial preference instead of just the pros. In turn, such divergent thinking leads to better decision-making. She writes, “Dissent is a liberator,” because it frees us from prematurely and suboptimally narrowing agreement.
Now the part that’s harder for me to absorb, because it challenges my predispositions. Nemeth is emphatic that the benefit accrues from authentic dissent presented with conviction. That is, divergent thinking requires a minority view that someone actually holds and is willing to defend. In her studies, the difference between real and performative dissent is between benefiting the group and backfiring.
Staged devil’s advocacy doesn’t work and may do harm. When a group knows the objection is staged, it doesn’t open up the discussion. It does the opposite: it marshals reasons that the original consensus was right all along. Performed dissent can leave a group with the false confidence that it has weighed every angle while it quietly congealed around the first one. That may well be worse than never raising the objection at all.
An authentic dissenter pays a price. The person whose genuine objection improves everyone’s thinking is reliably disliked for it. Furthermore, they won’t get credit for improving the group’s decision-making performance. The benefit is collective; the cost is personal.
According to Nemeth, for dissent to do its work, it has to be authentic, held with conviction, and expressed with some persistence. The dissenter who believes in their position and won’t fold under the inevitable cross-examination by the majority is the one who makes you wonder whether you might just be wrong.
The Limits of Anonymity
The Reflect & Engage method removes the social pressures that keep groups from using what they already know, and one of the things it removes is the name attached to a point of view. People reflect independently and anonymously, and what reaches the facilitator is a map of real tensions, with the authors' identities stripped away.
Anonymity is what helps surface authentic dissent in the first place.3 When a facilitator raises an anonymized doubt, the room receives an authentic disagreement without a named owner. From the group’s vantage point, an unowned objection and a devil’s advocate objection can look similar, and it’s tempting to assume the group metabolizes them the same way by defensively bolstering the position the doubt was meant to challenge.4
But that assumption breaks down: a staged objection and an anonymous one are not the same thing. When a group knows an objection was assigned, it knows the objection is, in a sense, false. No one in the room actually holds it. An anonymized doubt is real. Someone submitted it because they meant it. I’m assuming that the cognitive bolstering Nemeth documents is provoked by perceived insincerity, and an unowned doubt is not insincere.5 It is only faceless.
Even so, anonymity does not provide what Nemeth says actually does the work. Her dissenter changes minds not simply by being sincere but by being persistent — by holding the position under the majority’s cross-examination and refusing to fold. That persistence is the visible evidence of conviction, and it is precisely what anonymity cannot transmit. An anonymized doubt arrives real and then says nothing more. It cannot answer the first rebuttal, absorb the second, or make the room wonder whether its holder knows something the room doesn’t. So it is neither staged dissent nor embodied dissent. It is a third thing: authentic but inert.
So here’s the dilemma: the anonymity that makes candor less expensive can present authentic dissent to the group while removing the visible evidence of the conviction required to trigger the divergent thinking necessary to improve decision-making. The failure isn’t that the doubt is fake; it’s that it’s heard once and then can’t defend itself. Methods like Reflect & Engage risk surfacing real dissent and letting it go inert, and the better the production values, the more convincing the illusion of having considered all sides.6
Nemeth acknowledges the dilemma. On the one hand, she observes,
There are some relatively easy fixes…ways we can reduce our fear of being different or our fear of reprisals for going against the majority. One specific way to reduce that fear is through anonymity…Another way…is to make a commitment prior to hearing the opinions of others.
Presumably, she would approve of the independent and anonymous solicitation of input that is the centerpiece of Reflect & Engage. On the other hand, she cautions,
[M]any people — researchers, practitioners, and laypeople alike — tell us that the real key to making good decisions is diversity or some kind of technique that plants dissent without needing a true dissenter.
She acknowledges the potential value of cognitive diversity, “provided the differences are expressed.” Nemeth dismisses as contrivances techniques that obscure the authenticity and conviction of dissent. Authentic dissent is an essential ingredient, but visible conviction is the catalyst that activates divergent thinking.
Why the Ghost Has to Be Banished
I’ve treated the ghost in the room as a cost to the dissenter — the anonymity meant to protect them triggers a manhunt instead. Nemeth’s work makes me see the ghost in a different light. The ghost isn’t only a problem of attention; it’s a problem of perceived conviction. A doubt that belongs to no one may be a doubt that no one takes seriously, and a doubt that no one takes seriously is the exact condition she found doesn’t work. So banishing the ghost isn’t a courtesy extended to the dissenter. It’s the thing that makes the dissent more real once it’s surfaced.
I see two ways to banish the ghost. Either the room collectively takes ownership of the doubt — a shared assumption rather than someone’s complaint — or the person who actually holds the view steps forward and claims it in front of everyone.7 The first route validates the doubt by making it the room’s; it depends on how the facilitator frames the question and whether they give the room a second chance to originate the concern before anyone has to own it.8 The second gives the dissenting voice a face and the possibility of conveying conviction.
Dissent as a Public Good
Nemeth’s observations illustrate what economists would recognize as a public good. It is non-excludable. Everyone in the group benefits from better collective thinking, whether or not they spoke up. It’s non-rivalrous. One person’s cognitive gain from the dissenter’s challenge does not reduce another’s.
The costs of dissent, however, are private and excludable, including social rejection, reputational damage, marginalization, and career risk. These fall exclusively on the dissenter.
This structure produces chronic under-supply. Rational actors free-ride; they silently enjoy the fruits of others’ courage without incurring any personal cost. Consequently, the group gets less dissent than it needs.
Nemeth exhorts the individual to be courageous and to persist in the face of hostility. She asks leaders to create cultures of respect. She’s persuaded me to recognize more clearly that there will be times when individual courage is necessary to give a dissenting opinion a name and a face. Nevertheless, I remain convinced that structural approaches are also necessary.9
Where This Leaves Me
The banishing of the ghost happens in a room that I’m not in. I can do the part before the meeting. I can help surface authentic doubt, hand the facilitator a map of it, and suggest questions and facilitation techniques designed to present the dissenter with the option — but not the obligation — to step forward to claim their viewpoint. What I can’t do is make anyone exercise the option. I can’t be there to convert theirs into ours in real time, and I can’t supply conviction by proxy.
So the uncomfortable possibility remains on the table. If no one owns the doubt and the room never makes it its own, the Reflect & Engage method hasn’t escaped Nemeth’s trap. It’s furnished a polished version.
That said, the bet was never that I could remove courage from the room. It’s that I could shift the moment courage is required to the cheapest point possible and hope that cheap enough, often enough, is enough to help facilitators keep the “groan zone” open long enough for divergent thinking to take hold.
Whether that hope is warranted is decided by a person, in the moment, after my work is finished. Nemeth would probably tell me that’s exactly where the decision belongs. The troublemaker was always the point.
In “The Ghost in the Room,” I note, “The facilitator raises a concern without attribution — a doubt, not a person. Almost at once, before engaging with the substance of the objection, the room starts looking for the objector.”
Charlan Nemeth, In Defense of Troublemakers: The Power of Dissent in Life and Business (Basic Books, 2018). The contrast between authentic dissent and role-played devil’s advocacy, including the “cognitive bolstering” that staged dissent provokes, is among her most replicated results, alongside the companion finding that the useful dissenter tends to be disliked for their trouble.
I wrote about designing “safe harbors” in “Trustworthy by Design.”
I touched upon related themes in “Said Is Not Heard,” “You Can’t Engineer Being Heard,” and “The Wrong Kind of Safe.”
Anonymous input doesn’t guarantee sincerity. Online trolling is the obvious counterexample. But Reflect & Engage isn’t an open internet forum; it’s a bounded professional or organizational context where participants have skin in the game and a shared stake in the outcome. In that setting, sincerity is a reasonable working assumption, not a naïve one.
In “Escaping a Procrustean Bed,” I acknowledge, “Sophistication that cannot justify its complexity is theater with better lighting.”
Central to the facilitator’s craft is turning their objection into our question worth testing and discussing. I’ve examined the facilitator’s role in several essays, including “The Diversity Trap.”

The whistleblowing literature, which addresses the most consequential and costly form of organizational dissent, is unambiguous on this point: legal protection and formal institutional backing are the primary predictors of whether wrongdoing is reported, not individual moral character.
