argument_from_popular_practice
The argument from popular practice claims that an action is appropriate or justified because many people do it. Unlike the argument from popular opinion (which concerns belief), this scheme concerns behavior: the fact that a practice is widespread is used as evidence that it is acceptable, effective, or normatively correct. It can be valid when widespread adoption genuinely signals practical effectiveness, but fails when the practice persists due to inertia, ignorance, or collective irrationality.
Everyone in this industry uses unpaid internships. It is standard practice. There is nothing wrong with expecting our interns to work without compensation since that is simply how things are done.
A manager defends the team's habit of sending work emails late at night and on weekends: 'Look, in this industry everyone is always on. You check your messages whenever they come in — that's just the culture here. It's not unusual; it's how things work in high-performing teams.' The widespread practice is used to justify what might otherwise be seen as an unhealthy norm.
A teenager argues with his parents: 'Literally all of my friends are allowed to have social media accounts — every single one of them. It's completely normal for kids my age. You're the only parents who still say no.' The universality of the practice among peers is offered as justification for why the rule should change.
Binary (yes/no) questions an LLM must answer to identify this aspect:
Is there evidence that the practice is actually widespread?
Type: binaryIs the prevalence of the practice being used to justify its correctness?
Type: binaryCould the widespread practice still be harmful or irrational?
Type: binaryAre the circumstances of other practitioners relevantly similar?

Behavioral conformity reduces social risk and decision costs. If many people do something without apparent negative consequences, it creates a presumption that the practice is safe, effective, and socially sanctioned.
Distinguish between 'common' and 'correct.' Ask whether the practice actually produces good outcomes, whether people have considered alternatives, and whether the practice persists due to tradition, power dynamics, or lack of better information.
Popular practice arguments appear in workplace culture (hazing, overwork), tax compliance ('everyone cheats on their taxes'), environmental behavior, and professional norms in various industries.
