Fallacy of Impossible Rationality

The practice of demanding that an opponent's reasoning be free of any and all cognitive bias, emotional influence, or cultural perspective before it can be considered valid. It sets an unattainable standard of "pure reason" that no human has ever achieved, then uses the inevitable failure to meet it as grounds for dismissal. This fallacy is common among those who have just discovered that biases exist and now use that discovery to disqualify any argument they disagree with. "You only believe that because of confirmation bias" becomes a conversation-ender, as if having a bias automatically makes a claim false, and as if the speaker themselves were miraculously bias-free.

Example: "He dismissed every study I cited with 'that's just your Western rationality'—a Fallacy of Impossible Rationality pretending that because perfect objectivity doesn't exist, all reasoning is equally worthless."

Fallacy of Impossible Reason

A close cousin to impossible rationality, this fallacy demands that an opponent's reasoning process be flawless, complete, and self-contained according to an impossibly strict standard before it can be engaged with. It's the "gotcha" of pointing out that an argument has unstated premises, that it relies on some assumptions, or that it isn't mathematically formalized—as if any human communication could meet such standards. The fallacy lies in using the inevitable gaps and imperfections in all reasoning as an excuse to reject the reasoning entirely, rather than engaging with its substance. It turns the legitimate observation that "no argument is perfect" into the illegitimate conclusion that "therefore no argument is worthwhile."

Example: "He demanded I write my position as a series of formal logical propositions with every premise explicitly stated—a Fallacy of Impossible Reason designed to make conversation so tedious I'd just give up."

Fella Bird

A very close ally to oneself. Common examples are friends in the inner circle that are accepting of one's wild and more socially questionable side. The full, official title is Fella Geezer Bird, but due to practicality and the term being popularly overused in speech it often gets shortened to Fella Bird.

If you address someone by this term, you respect them at the highest level in the most modest and subtle way. One doesn't need to doubt if they are loved in this world if they are addressed by a fellow Fella Bird.

"Alright fella bird what's going on then? "
"Alright bubs get me the big bag a discos, the big pack a ten, cheers fella bird."

Fallacy

A mistaken belief.

Hym "I mean, the level of fallacy being espoused is ridiculous. Fallacy means literally 'that you are mistaken in believing that the words that you are saying is consistent with the conclusion you are drawing' and, therefore, aren't justified in saying it or acting on the conclusion. Fallacy = Retarded."
