A contradiction map shows when two statements cannot both be true - and why the difference matters to the outcome.
Organisations often describe the same event differently at different stages. Not every wording difference is material. A useful contradiction is one that changes a fact relevant to liability, jurisdiction, remedy or credibility - for example “accepted” versus “declined”, “balance was £0” versus “balance was £200”, or different dates for the same notice.
Map each statement to its source and date. Then explain the issue that turns on the difference.
Key points
- Quote both versions accurately.
- Identify who made each statement and when.
- Explain why both cannot stand together, if that is genuinely the case.
- State what evidence could resolve the conflict.
A contradiction schedule
| Statement A | Exact quote/source/date |
|---|---|
| Statement B | Exact quote/source/date |
| Conflict | What factual point differs |
| Why it matters | Effect on complaint issue |
| Resolution needed | Which record or finding would settle it |
Not every difference is a contradiction
“We cannot find the recording” and “no recording was made” are different statements but not necessarily logically incompatible. Be precise. Likewise, an early estimate and later confirmed figure may simply reflect new information.
Contradictions can expose process problems
If a final response, internal record and ombudsman submission each give a different account, the decision-maker should identify which version is supported and why. Repetition of the latest version is not analysis.
In practice
- Use a table rather than rhetorical commentary.
- Focus on contradictions that affect an issue.
- Ask the organisation to reconcile them expressly.
What to do
A practical next-step plan
- Collect all versions of the relevant statement.
- Quote them verbatim and date them.
- Define the factual point in dispute.
- Find independent records that could resolve it.
- Put the contradiction to the organisation/decision-maker.
- Record whether the final outcome actually reconciles it.
Common traps
Things that often confuse the issue
- Do not call a minor wording change dishonesty without evidence.
- Do not omit context around a quote.
- Do not build a schedule so large that trivial inconsistencies obscure decisive ones.
Evidence worth keeping
Tie each contradiction to an issue or remedy.
Useful wording.
“Please reconcile statements A and B. They appear incompatible because [reason]. This matters to issue [x] because your conclusion depends on [proposition]. If one statement is incorrect, please identify which one and correct the record.”
Contradictions that do not affect liability, process or remedy can distract from stronger points.
Give the other side a fair opportunity to reconcile it.
A strong complaint does not assume every discrepancy proves dishonesty. Ask whether one statement was wrong, used a different definition or relied on new evidence. The failure to provide a coherent reconciliation can itself become important later.
Classify the contradiction.
- Factual contradiction: two incompatible accounts of what happened.
- Chronology contradiction: dates/events cannot both be correct.
- Document contradiction: a contemporaneous record conflicts with a later narrative.
- Reasoning contradiction: conclusion does not follow from accepted facts.
- Policy/process contradiction: stated process differs from recorded handling.
That classification helps explain why the inconsistency matters.
A contradiction schedule should compare like with like.
Place the two statements side by side, identify their source and date, and explain the proposition on which they conflict. Avoid presenting two statements as contradictory if they address different periods, definitions or questions. The value is in proving a genuine inconsistency, not accumulating dramatic-looking quotes.
| Source A | Source B | Issue |
|---|---|---|
| Final response: “order was accepted” | Later submission: “application was declined” | Status of the transaction at the same decision point. |
| Bill: £70 outstanding | Ledger: £20 credit applied before bill | Accuracy of final balance. |
| Policy says review completed | Case note says review pending | Whether stated investigation actually occurred. |
