Appeal to tradition

What it is

Argues that something is right or better because it has long been done or believed.

Example "We've always done it this way, so it's the right way."

Appeal to popularity fallacy
Popularity across space (bandwagon) and across time (tradition) are both substitutes for evidence about truth.
Status quo bias bias
Appeal to tradition is status quo bias as an argument: how things are done is treated as a reason.
Appeal to novelty fallacy
These are mirror images: one treats old as better, the other treats new as better.
Mere-exposure effect bias
What is familiar feels right, which gives tradition its quiet persuasive power.
Etymological fallacy fallacy
Insisting on a word's old meaning appeals to the authority of its origin.
