At a meeting, everyone praises a plan. Several participants privately expect it to fail, but each believes that saying so would damage their position. Observers see apparent unanimity and conclude that the plan has broad support.
Preference falsification describes a gap between a person’s privately held preference and the preference they publicly express under social pressure. It can help explain why an arrangement seems stable until a change makes previously hidden disagreement visible.
A shift in expression can look like a sudden change of mind
One respected person speaking openly may lower the perceived cost for others. The public picture can then change faster than the underlying private opinions did. But that is a possible mechanism, not grounds for assuming that every surprising reversal reveals secret beliefs.
People can be silent because they are uncertain, uninterested, or still thinking. They can also sincerely change their minds. Treating disagreement as always hidden somewhere would make the explanation impossible to test.
The useful investigation concerns incentives for expression: what happens to dissenters, whether people can disagree privately or anonymously, and whether leaders receive information that challenges their preferred account. A public consensus is easier to interpret when the conditions allow people to reveal genuine disagreement without disproportionate personal cost.
