Today's Logical Fallacy is... Appeal to Nature!



This fallacy stems from the idea that just because something is “natural” means that it is good, valid, justified, inevitable, or ideal. While many “natural” things are “good,” that doesn’t mean that all natural things are good and all unnatural things are bad. For example, infanticide is “natural;” that doesn’t mean it should be considered “good” or acceptable.

Today's Logical Fallacy is... Red Herring!

(Ignoratio Elenchi, Ignorance of Refutation, beside the point, misdirection, changing the subject, false emphasis, the Chewbacca defense, irrelevant conclusion, irrelevant thesis, smokescreen, clouding the issue, judgmental language, fallacy of distraction) 

This fallacy occurs when someone uses an irrelevant distraction, intentionally or unintentionally, to divert or mislead an audience. We most often recognize this as “changing the topic,” but sometimes the topic is so emotionally loaded or the new topic is seemingly related to the original topic that we don’t recognize it. The fallacy gets its name from fox hunting: smoked herrings, often red, are used to throw the hounds from the scent of the fox. Many fallacies are types of red herrings including appeals to pity, consequences, and the straw man fallacy.

Today's Logical Fallacy is... Anecdotal Fallacy!

[the "I know a person who" fallacy]

This logical fallacy is committed when someone rejects or discounts extensive evidence in favor of an isolated or personal experience. This is often used as the basis for the overgeneralization fallacy and is linked to the Post hoc ergo propter hoc (correlation/causation) fallacy, a fallacy that assumes a causal relationship where none exists.

Today's Logical Fallacy is... Association Fallacy!

(They're Not Like Us, Guilt by Association, Honor by Association, a variety of the Ad Hominem and Hasty Generalization)

This fallacy occurs when someone’s argument or position is dismissed (or upheld) because of the group to which that person belongs. Often referred to as the “They’re Not Like Us” fallacy, this is the basis for bigotry and racism. It’s a type of Ad Hominem Fallacy (as it dismisses the argument based on the individual making it), a Red Herring (as it is a distraction from the actual issue), and a Hasty Generalization (as it uses implied stereotypes), and it can often be an Appeal to Emotion (as the stereotypes often invoke an emotional response as means to dismiss the position).
