Preference Cascade

The situation where people's private opinions reach a tipping point and become publicly expressed and accepted. https://en.wiktionary.org/wiki/preference_cascade

Preference falsification is the act of misrepresenting a preference under perceived public pressure. It involves publicly expressing a preference that differs from one's underlying privately held preference (or simply, a public preference at odds with one’s private preference). People frequently convey to each other preferences that differ from what they would communicate privately under credible cover of anonymity (such as in opinion surveys to researchers or pollsters).[1] Techniques such as list experiments[2] can be used to uncover preference falsification.[3][4].. When private opinion and public opinion are far apart, a shock of the right kind can make a critical number of disgruntled individuals reach their thresholds for expressing themselves truthfully to put in motion a public-preference cascade (also known as a public-preference bandwagon, or, when the form of preference is clear from the context, a preference cascade). Until the critical mass is reached, changes in individual dispositions are invisible to outsiders, even to one another. https://en.wikipedia.org/wiki/Preference_falsification
