What this image shows

A smiling man in a suit holds up a jar of capsules while gesturing enthusiastically, a meditating woman floats above surrounded by glowing clouds, stars, and a crescent moon, and another man examines a jar labeled "Mystic Pills" using a magnifying glass next to a microscope and checklist. The image suggests that these pills offer hidden or mystical benefits by invoking ideas of inner energies or spiritual harmony, which are shown as glowing clouds and celestial symbols. The important contrast is between the fanciful, magical atmosphere and symbols surrounding the pills and the attempt by the serious investigator to test or verify them with scientific tools. We can see clouds, light, and symbols around the woman and pills, but these effects do not provide concrete evidence that the pills have any real, testable mystical power.

Why it misleads

A fuller explanation of how the fallacy works and why it can look persuasive.

Vagueness can be useful early in exploration, but it becomes fallacious when the fog is preserved to prevent serious evaluation. If key terms cannot be pinned down, the claim can keep slipping away from critique.

That's like saying...

Instead of leading with the label, this analogy answers the shape of the reasoning move directly so the mistake is easier to see in plain language.

Fallacious claim

These capsules restore your body's subtle energies and harmonize your inner system.

That's like saying...

That's like writing a doctor's note that says the machine failed because the patient's vibes were misaligned. Vague elastic terms are being chosen so the claim cannot be pinned down or tested.

Caveat

This label is easy to overuse. The point here is not to call every weak argument by this name, but to reserve it for the exact misstep it describes.

Common misapplication

Do not use this label every time an argument feels unfair, heated, or evasive. It applies when the move really does distract from, pressure, or replace the reasoning at issue. Vagueness can be useful early in exploration, but it becomes fallacious when the fog is preserved to prevent serious evaluation.

Use the label only when...

Use this label only when vague, elastic, or undefined terms are chosen so that a position sounds meaningful while resisting clear testing or criticism. If the real problem is that words are selectively excerpted from their original context in a way that changes or distorts what the speaker meant, the better label is Contextomy.
