November 10, 2014Question about the validity of informal fallacies
Talking about validity and informal fallacies together can get pretty confusing. Informal fallacies are mostly matters for informal logic whereas validity is a feature of formal arguments. Informal arguments are often not even given in a form which is immediately amenable to formalization without adding a bunch of stuff which hasn't been said. So, I would just avoid thinking this way insofar as you can. Generally, validity isn't a helpful standard in natural language arguments. One way to schematize classical fallacy theory is to say that informal fallacies arise when a disputant has advanced a piece of evidence toward a conclusion which is prima facie (1) insufficient, (2) relevant, or (3) clear. And, in particular, it needs to do this within some kind of pattern which does actually occur in natural language arguments. So, the slippery slope fallacy is supposedly a pattern of reasoning whereby a disputant offers a piece of evidence which seems clear and relevant to the conclusion, but isn't sufficient to motivate it (because it requires us to slip farther than we're warranted down some slope).

January 9, 2020TIL the fallacy fallacy is the formal fallacy of analyzing an argument and inferring that, since it contains a fallacy, its conclusion must be false.
I see this often on internet 'discussions'. There is always someone, who likely reads every social econ book that comes out and feels the need to impress its ideas on everyone around them, who shoehorns a fallacy into everything and thus thinks they have nullified the counter argument.

August 31, 2023 - In contrast, informal fallacies arise from issues with the content or context of the premises rather than the argument's structure. These fallacies often involve errors in reasoning, such as appeals to emotion or relevance. While arguments with formal fallacies are always invalid and cannot guarantee a true conclusion, those with informal fallacies might still have true conclusions but suffer from problematic reasoning...

April 21, 2023 - As such, we know that the argument is invalid, even though we haven’t got a clue what “toves” are or what “slithy” or “brillig” means. The point is that we can identify formal fallacies without having to know what they mean. In contrast, informal fallacies are those which cannot be identified without understanding the concepts involved in the argument.

The Subtle Dance of Logic: Unpacking Formal vs. Informal Fallacies - Oreate AI Blog
January 27, 2026 - A classic example of a formal fallacy is the "Affirming the Consequent." If we say, "If it's raining, the ground is wet," and then observe, "The ground is wet," it doesn't automatically mean "It's raining." The ground could be wet for other reasons, like a sprinkler. The structure of the argument doesn't hold up. Informal fallacies, on the other hand, are a bit more nuanced.
