There is a moment, when a community is afraid, in which something changes in how it reasons. Not so much in each person — who, taken one by one, may stay clear-headed — but in the group: opinions fall into line, anyone who thinks differently becomes suspect, and measures that seemed unthinkable the day before start to look like common sense. You don’t need to imagine a hidden hand to explain it. The psychology is enough, and it is documented. This article tries to look at it honestly: how fear and conformity work together, and why it’s worth knowing.
Why fear and conformity go together
The link is not a hunch; it has been measured. In a classic study, Darley (1966) raised participants’ fear (with the threat of an electric shock) and then put them in an Asch-style conformity situation: the frightened participants conformed markedly more than the calm ones — and most of all when the pressure came from others facing the same threat. Fear, in other words, doesn’t just make us anxious; it makes us look to the group to know how to react, and to go along with it.
As for the deeper why, one of the better-known accounts is terror management theory. According to this line of research, when thoughts of death become salient people defend their shared worldview more fiercely, show more support for charismatic leaders, and react with more hostility toward those outside the group or who threaten its values (Greenberg, 2008). It’s worth saying plainly, with the same honesty I ask of myself: this theory is influential but contested. A large multi-lab replication (Many Labs 4) failed to reproduce the classic effect, and the debate is open. I take it not as a law, but as one of the better available frames — and one that converges with more solid experiments.
We conform even against the evidence
One of those more solid experiments is the classic by Solomon Asch (1955). A person was placed in a group of confederates who unanimously gave an obviously wrong answer to a very simple question. Rather than break with the group, the participant ended up giving the wrong answer too about a third of the time. Not because they couldn’t see: because seeing alone, against everyone, costs something. The fear of being the only one out of step is enough, on its own, to bend judgment.
The rule that outlives its reason — and punishes whoever breaks it
Then there is a second step, more unsettling: a norm can outlive the reason it was born for, and the group itself takes over enforcing it. Jacobs and Campbell (1961) had confederates impose an arbitrary norm on a group, then replaced the members one by one: the norm kept being passed down for several “generations,” even when no one was left who knew its origin. It’s the same mechanism as the parable I’ve told elsewhere, the five monkeys experiment: at a certain point the limit no longer needs a visible external authority. The group keeps it in place.
And it keeps it in place with aggression, too. Within the same terror-management research, some studies found that, once thoughts of death were made salient, people became more punitive toward those who threatened their worldview (McGregor et al., 1998). A frightened group doesn’t just conform: it tends to make the dissenter a target. That’s how the pressure stops coming from above and starts circulating among peers.
When fear becomes a tool
None of this stays in the lab. People who work in communication know it, and sometimes put it in writing. A documented example: in March 2020 the behavioral-science group advising the UK government (SPI-B) stated, in an official document, that to increase adherence to the measures “the perceived level of personal threat” should be raised among those who were too relaxed, “using hard-hitting emotional messaging” (Options for increasing adherence to social distancing measures, 2020). In other words: deliberately raising fear as a lever of communication.
I bring it onto the plane that matters here — communication, not the merits of the decisions — because it’s exactly the dynamic this article is about, and because it also shows the flip side. The later research is anything but enthusiastic: a 2022 study found that fear-based messages did not increase people’s intention to follow the guidance, and could instead heighten health anxiety (Richmond, Sharpe and Menzies, 2022). Fear, as a tool, is both ethically questionable and often ineffective: it buys acquiescence, not informed agreement.
What was unthinkable becomes normal
There’s a last effect, and it concerns the boundary of what a society is willing even to discuss. Under the push of fear that boundary shifts fast: positions that seemed extreme become “reasonable” within weeks. It’s the phenomenon I described in writing about the Overton window. Not because someone “moves the window” from a control room, but because fear makes acceptable what wasn’t before — and defuses objections before they’re even formed.
Recognizing it without being naive
Here the same double honesty is needed that I try to keep on everything. On one side, it would be naive to deny that fear gets used: the SPI-B example isn’t a suspicion, it’s a document. Interests, strategic communication and the management of consent exist, and it’s healthy to see them rather than look away. On the other, it would be just as naive to read a single directing hand behind it all: most of what happens needs no plot — the psychology of a frightened group, the inertia of institutions, and the spontaneous alignment of many interests pushing the same way are enough.
The antidote, then, is neither paranoia nor blind trust. It’s simpler and harder: noticing when you’re afraid, and asking whether it’s the fear talking. Judging an idea by what it’s worth, not by how widespread it is or how risky it is to dissent. Telling apart what you’ve chosen from what you’ve merely fallen in line with. It doesn’t make us immune — but it gives back a margin. And in a frightened group, that margin is the most valuable thing we have.
