Formal Fallacies
A formal fallacy is an error in logic that can be seen in the argument's form. All formal fallacies are specific types of non sequiturs.
- Appeal to probability – takes something for granted because it would probably be the case (or might be the case).
- Argument from fallacy – assumes that if an argument for some conclusion is fallacious, then the conclusion itself is false.
- Base rate fallacy – making a probability judgement based on conditional probabilities, without taking into account the effect of prior probabilities.
- Conjunction fallacy – assumption that an outcome simultaneously satisfying multiple conditions is more probable than an outcome satisfying a single one of them.
- Masked man fallacy (illicit substitution of identicals) – the substitution of identical designators in a true statement can lead to a false one.

Famous quotes containing the word formal:
“Then the justice,
In fair round belly with good capon lined,
With eyes severe and beard of formal cut,
Full of wise saws and modern instances;
And so he plays his part.”
—William Shakespeare (15641616)
