True False Not Given Trap Psychology: Why IELTS Reading Feels Unfair
TFNG · Distractor design · May 2026
Direct answer
TFNG traps work because your brain prefers certainty over precision—TRUE and FALSE options feel decidable from keyword match, while NOT GIVEN feels like a failure to find proof. Examiners place statements that are plausible, topic-aligned, and lexically familiar but not logically entailed by the passage. Band 7+ readers disqualify options with one constraint test instead of re-reading until feelings settle.
The psychology behind TFNG mistakes
Confirmation bias pushes TRUE when you recognize words. Negation blindness pushes FALSE when you miss one qualifier. NOT GIVEN triggers frustration, so students invent connections—see Reading distractor psychology.
TRUE trap Topic match without full entailment
FALSE trap Opposite of a detail, not the whole statement
NG trap Passage silent on the exact claim
Designer patterns in TFNG sets
| Statement type | Common wrong pick |
|---|---|
| Scope shift (all vs some) | TRUE from partial evidence |
| Future prediction | FALSE when passage is silent (should be NG) |
| Comparison reversed | TRUE from familiar comparison words |
TFNG decision protocol (10 seconds)
- Underline modal words (all, some, never, may, often).
- Ask: does the passage state this or only related topic?
- If silent on the exact claim → NOT GIVEN (stop searching).
- Drill with guided Reading practice.
Key takeaways
- TFNG punishes certainty feelings, not vocabulary alone.
- NOT GIVEN means silent on the exact claim—not hard to find.
- Modal words and scope are primary filters.
- Log trap type per mistake to break repetition.

Locate once, decide on logic—avoid endless re-reading.
Overlap flags help; manual constraint checking remains essential.
