Accordingly, the fallacy fallacy is an informal logical fallacy , since there is an issue with its premises, and namely with the false premise that if an argument is fallacious, then its conclusion must be false.
As one book on the topic states:. Fallacies are errors in reasoning, not errors about truth or falsity. In addition, the fallacy fallacy is sometimes also used to refer to cases where people assume that if an argument is fallacious in one aspect, then it must also be fallacious in all of its aspects.
This is illustrated in the following dialogue:. Alex: all foxes have tails, and the animal that just ran into the bush had a tail, so it must be a fox. Here, Alex uses fallacious reasoning when deducing that the animal that he saw was a fox, as Bob points out. This argument illustrates the fallacy of affirming the consequent.
