Argumentum ad populum
Following the crowd down the run.
Popularity isn’t proof.
Example
“Everyone in Truckee believes it, so it must be true.”
“Argument to the people.” Related forms include consensus gentium (the consent of nations) and ad numerum (appeal to numbers).
Diagnosis: Majorities have been wrong about geocentrism, slavery, and much else. Popularity can be modest evidence when the crowd is independent and informed, but never sufficient alone.
“Billions of people believe in God, so God exists.” The consensus gentium argument is more defensible when framed as evidence of a widespread sensus divinitatis — but it still needs that further argument.
“Most Christians today accept this practice, so it’s biblical.” Prophets and reformers — including early Friends — often stood against the majority.
“The majority of commentaries take this view.” Scholarly consensus is a meaningful signal, but the grounds of the consensus are what persuade.
Trail recovery
Look past the headcount to the reasons. In papers, cite consensus as a starting point and then explain why the experts hold that view.
Try saying: “That’s a widely held view — what are the main reasons people find it convincing?”
Keep questioning. Keep exploring.
