Choose the best analysis for each fictional scenario. The explanations focus on timing, relevance, scope, and whether the statement proposes a fair test.

Method#

  1. Identify the claim that needs evaluation.
  2. Mark any framing supplied before the claim.
  3. Ask whether the framing identifies a specific reliability risk.
  4. Ask whether evidence will still be examined.

Eight scenarios

Select one answer for each question, then check your score and read every explanation.

1. Before Leila presents a cost analysis, the chair says, “Leila has opposed this project from the start, so keep her negativity in mind.” What is the best analysis?
2. “This trial was funded by the manufacturer. Compare its protocol and results with independent trials.” What is the best analysis?
3. A proposal requests a two-week pilot. A critic replies, “They want to ban the technology forever.” Which fallacy is clearest?
4. Nora says the required inspection is missing. The manager replies, “You missed an inspection last year.” Which pattern is clearest?
5. “The report says 38%, but recalculating its linked dataset gives 13%.” What is the best analysis?
6. “Why should we listen to a witness as dishonest as Kai?” asked before Kai testifies. Which answer is best?
7. During a budget audit, a manager changes the subject to the office furniture. What pattern is clearest?
8. “The photograph was posted by an advocate. Verify its time, location, editing history, and corroborating footage.” What is the best analysis?

Answer key

Answer to question 1

Poisoning the well

The chair supplies a broad character frame before the analysis and gives no method for checking its calculations.

Answer to question 2

Potentially fair source criticism

The conflict is relevant and leads to a proportionate check rather than automatic rejection.

Answer to question 3

Straw man

The response changes the content of the proposal from a pilot to a permanent ban.

Answer to question 4

Tu quoque

The manager responds to criticism with a hypocrisy charge, leaving the present missing inspection unresolved.

Answer to question 5

Direct evidential criticism

The statement identifies a specific, reproducible conflict with the reported figure.

Answer to question 6

Loaded question that may also poison the well

The question presupposes dishonesty and broadcasts that discrediting premise before testimony.

Answer to question 7

Red herring

The furniture issue diverts the discussion without necessarily attacking a source.

Answer to question 8

Responsible provenance check

Origin motivates authentication but is not treated as proof that the photograph is false.
