Weasel Words

What it means

Weasel words are phrases that create the impression of a clear, meaningful statement while actually saying very little. They hedge, qualify, and attribute claims to unnamed sources in ways that let the speaker sound authoritative without being accountable for anything specific.

The term comes from the idea of a weasel sucking the contents out of an egg, leaving the shell intact but empty. That’s exactly what these phrases do to arguments - they preserve the shape of a claim while removing its substance.

“Some people say…” Who? How many? On what basis? “Studies suggest…” Which studies? Published where? Peer-reviewed? “Up to 50% off…” So anywhere from 0% to 50%? “Helps reduce the appearance of wrinkles…” Helps how much? Reduce by how much? The appearance of, not actual wrinkles?

Every one of these phrases is technically defensible - which is precisely the point. They’re designed to create an impression that can’t quite be called a lie.

In the real world

Advertising runs on weasel words. “Clinically proven” sounds like hard science, but proven to do what, exactly? A moisturiser that’s “clinically proven to hydrate” might simply mean that in a study, people who used it reported their skin felt less dry. “Up to” is perhaps the most successful weasel phrase in commercial history - it puts the best possible number in front of you while committing to nothing.

In politics, weasel words are the escape hatch. “Mistakes were made” is the classic - a phrase that acknowledges error without admitting who made it or taking responsibility. “Many people are saying…” attributes a claim to an undefined crowd, making it sound like common knowledge while keeping the speaker one step removed from the assertion.

News coverage falls into this trap too. “Sources say…” can mean anything from a senior government official speaking on background to someone’s cousin at the pub. Without specificity, the phrase lends weight to claims that may not deserve it.
