Double-Negative Traps in IELTS Reading: When “Not Uncommon” Flips the Answer
Polarity · T/F/NG · May 2026
Updated
Double-negative traps in IELTS Reading flip polarity: the passage says “not uncommon” (meaning it happens) and the statement says “rare,” or “unless” hides the only condition that makes a sentence true. Keyword matching keeps the topic and drops the nots. Underline every negative particle before you choose True/False/Yes/No/Not Given.

What polarity items are testing
The paper rewards careful logic, not vocabulary overlap. Two negatives can restore a positive meaning. One negative plus a restrictor (“only,” “never,” “unless”) can make a close paraphrase False.
How double negatives steal T/F/NG
| Pattern | What goes wrong | Correct move |
|---|---|---|
| Litotes | “not uncommon” vs statement “rare” | Paraphrase to a positive before matching |
| Unless vs if | You treat them as synonyms | Unless = except when; that can invert the condition |
| Scope of never | Never applies to one group; statement universalises | Match who the negative covers |
A polarity check before you tick
1. Circle not/never/no/unless/without/hardly
In both passage and statement.
2. Rewrite the sentence as a positive
On scrap: “it is common that…”
3. Only then compare
Topic overlap is not polarity overlap.
4. If a negative is unstated, it is NG, not False
False needs a contradiction, not a missing not.
Key takeaways: Double-Negative Traps in IELTS Reading
- Polarity is a Reading skill, not a vocabulary skill.
- Litotes often means the positive.
- Unless is not a casual if.
- Missing negatives are Not Given, not automatic False.
