DESCRIPTION
The Appeal to Common Practice is a fallacy with
the following structure:
1) X is a common action.
2) Therefore X is
correct/moral/justified/reasonable, etc.
The basic idea behind the fallacy is that the fact
that most people do X is used as “evidence” to
support the action or practice. It is a fallacy
because the mere fact that most people do
something does not make it correct, moral,
EXAMPLES
- Most people go at least 10 miles per hour over
the speed limit, so no one will care if you do
that, too.
- Everyone at this company takes home a few
office supplies for themselves, so you do it as
well.
- Yeah, I know some people say that cheating on
tests is wrong. But we all know that everyone
does it, so it’s okay.
- It's okay to let your children spend the night at
the house of someone you don't really know
EXCEPTIONS
- Democracy: not every decision made by society is a
right one. That is one of the main reasons for
democracy to be criticized.
- Customs/traditions: usually they have no logical
reasons for existence. But if what is moral is
determined by what is commonly practiced, then this
argument:
1) Most people do X;
2) Therefore X is morally correct.
would not be a fallacy.
- Language: if an incorrect expression is commonly
used, it becomes correct.
