The near-enemy of communication isn’t silence, there’s a more insidious menace— Logical fallacies.
I won’t deviate from my stance that the perceptual bias of labeling is a disasterous logical fallacy.
The latter can’t ever be quantified outside of the bias.

So in a nutshell, definitions are excruciatingly important when you are confronted with “labeling due to perceptual bias.”
Then you might ask, “Why would any definition serve a purpose? What is the WHY?”
Well, when perceptual bias adds an arbitrary label, the agreed-upon definition can potentially pave the way for future conversation, collaboration, and understanding.
Without the definition leading to potential agreed-upon thresholds, the “future why” of any project can easily become futile!

These days, when I encounter an opinion being preached as fact I say, “Thanks for mentioning that, let’s move on! Let’s address the practical stuff. ‘Let us do doable stuff?’”

Or maybe use an even “better” management tool for logical fallacies — Instead of quantifying, or attempting to quantify a label, just add “for whom” as a suffix to generalizations and rogue superlatives.
This is the best! — To which you could add, “The best for whom?”
You are narrow-minded — And you could ask, “Narrow-minded for whom?”

And There you go! You just received the best advice you’ll hear all day!
