Y12W25VC Evaluating information, seriously

You read an article online. It makes a striking claim. It cites a study. The writer sounds confident. What do you do next? If you're like most people, you either accept it or dismiss it. Neither is really evaluation. This week's article examines a specific skill — described by researchers who studied how fact-checkers actually work — that separates people who evaluate online information well from people who don't.

Figurative Phrases

take it at face value

accept without checking — idiom; 'face value' figurative

Etymology/Type: Idiom from currency and commerce; the "face value" of money is its nominal worth as printed (not its market value) - applied figuratively to accepting a claim without deeper scrutiny.

Synonyms: accept it without checking, take it as given, believe it uncritically

Example: She'd learned not to take statistics at face value after realising the headline figure came from a sample of twelve people.

In the articleThey take some deliberate practice.

check the facts

verify claims — idiom; facts aren't literally checked

Etymology/Type: Metaphor; facts are treated as if they were physical objects that can be "checked" (inspected or verified), though facts are abstract concepts not literally checkable.

Synonyms: verify the claims, fact-check it, confirm the accuracy

Example: Before citing the statistic in her essay, she stopped to check the facts and found the original study had been misrepresented.

In the articleYou either accept the claim — because the presentation seems reasonable and you don't have the time or expertise to check — or you reject it — because

read between the lines

infer unstated meaning — idiom; no literal lines

Etymology/Type: Metaphor; there are no literal lines to read between, but the phrase treats unstated or implied meaning as if it were hidden text that requires careful reading to discover.

Synonyms: catch the subtext, pick up on what's implied, find the hidden meaning

Example: Reading between the lines of the product review, she realised the "minor concerns" listed were actually serious problems.

In the articleThey read carefully.

under the surface

hidden below what's visible — idiom; 'surface' figurative

Etymology/Type: Metaphor from physical depth; what is "under the surface" is hidden below what is visible - applied to information that is not immediately apparent but lies beneath obvious appearances.

Synonyms: beneath the surface, below the obvious, underneath what's shown

Example: Under the surface of the persuasive headline was a study with significant methodological flaws.

In the articleThey also stayed on the site, also evaluated on surface cues, also failed to detect sophisticated deceptions.

sniff test

quick credibility check — idiom; not literal sniffing

Etymology/Type: Idiom from sensory perception; "sniff" (to smell) is not literally used, but the phrase borrows from the idea of quick sensory detection to mean a rapid, intuitive credibility check.

Synonyms: a quick credibility check, an initial plausibility test, a first-pass check

Example: The claim failed the sniff test immediately — no credible outlet had reported it, and the source was anonymous.

In the articleEvaluating information, seriously Here's a test.

cross-reference

check against another source — idiom; 'cross' figurative

Etymology/Type: Metaphor from navigation and comparison; "cross" means to traverse across or to compare across sources - checking information against another source to verify its accuracy.

Synonyms: verify across sources, check against other evidence, confirm independently

Example: She cross-referenced the statistic across three different databases before including it in her argument.

In the articleThey cross-referenced with multiple other sources.

Confusing Words

lateral vs literal

These look similar and sound like they could mean the same thing, but lateral and literal are completely different in meaning and usage—lateral is directional, while literal means 'exact' or 'not metaphorical.'

  • Lateral means sideways or across sources — it describes movement or comparison across multiple things. In the context of this module, lateral reading means checking a source by leaving it and consulting other sources about it, comparing across the web rather than going deeper into one source.
  • Literal means exact, word-for-word, or non-metaphorical — it describes something that should be understood in its plain, factual sense without interpretation or metaphor. A literal reading of a text means understanding it exactly as written, without assuming hidden meanings.

If you're comparing across multiple sources or perspectives, you're thinking *lateral*. If you're insisting on the exact, non-metaphorical meaning of words or facts, you're being *literal*.

credibility vs credible

These words come from the same root but they're different parts of speech—credibility is a noun (the quality itself), while credible is an adjective (describing something that has that quality).

  • Credibility is a noun: the quality or state of being believable. A source, person, or claim has credibility when it deserves to be trusted — when the evidence behind it is solid, or when the speaker has relevant expertise and a track record of honesty.
  • Credible is an adjective: worthy of belief or trust. You use it to describe something or someone that appears trustworthy — a credible witness, a credible claim, a credible source. It's the quality applied directly to a thing.

If you're talking about the *thing itself* (the trustworthiness), use credibility (noun). If you're describing *something as* trustworthy, use credible (adjective). Test: 'That source has high credibility' vs. 'That is a credible source.'

verify vs validate

These near-synonyms both involve checking, but they check for different things—verify checks whether something is true, while validate checks whether something is legitimate or meets a standard.

  • Verify means to establish the truth or accuracy of something — to confirm that a claim, fact, or piece of information is correct by checking against evidence. When you verify, you're asking: 'Is this actually true?' You verify facts against primary sources, cross-reference claims with authoritative data, or confirm that a quote is accurate.
  • Validate means to establish the legitimacy, worth, or acceptance of something — to confirm that it meets a standard, is acceptable, or has been properly authorized. When you validate, you're asking: 'Does this meet the criteria?' or 'Is this acceptable?' You validate a method, a feeling, someone's concerns, or a credential.

Use verify when checking for *truth* (fact-checking). Use validate when checking for *legitimacy* or *acceptance* (does it meet standards, is it approved, does it count?).
