Idioms, Fallacies, and Paradoxes

Argumentum Ad Nauseam

Argument from repetition signifies that it has been discussed extensively until nobody cares to discuss it anymore, sometimes confused by proof by assertion.

It is the logical fallacy that something becomes true if it is repeated often enough. An ad nauseam argument that can easily be shown to be false leads to the "point refuted a thousand times."

Repeating an opinion again and again seems to convince people that it is true - maybe because it simulates the effect of many people having that opinion.

Ad nauseam is the term for an argument or other discussion that has continued 'to (the point of) nausea'. For example, the sentence "This topic has been discussed ad nauseam" signifies that the topic in question has been discussed extensively, and that those involved in the discussion have grown tired of it.
