Critical Evaluation of Sources

The four criteria are credibility, provenance, relevance and (potential) bias.

(Currency — how up to date — and method/sufficiency are also useful additional checks.)

Citing a source means using it — quoting or referring to its content (e.g. "According to [source]…").

Evaluating a source means judging its quality and weight — assessing its credibility, provenance, relevance and bias, and saying how far it can be trusted. Component 2 requires you to evaluate every source, not just cite it.

Credibility: the tourism board is an organised, official body with relevant knowledge, but it is not independent on this question.

Provenance: it is a promotional brochure produced to attract visitors and investment — its purpose is marketing, not balanced analysis.

Relevance: highly relevant to a tourism question, and useful as evidence of the pro-tourism perspective.

Bias: there is a clear vested interest — the board benefits from more tourism, and the claim that tourism brings "only benefits" is conveniently one-sided, ignoring environmental and cultural costs.

Currency: at 2015 it is somewhat dated for current claims.

Overall judgement: the source is appropriate for representing the pro-tourism perspective but should be treated cautiously as evidence of tourism's actual effects, because its promotional purpose and vested interest make it one-sided. Its specific claims would need corroboration from independent, current sources before being given much weight.

Justification (appropriateness): the study is peer-reviewed and recent (2022), giving it strong credibility; published in an academic context with a transparent method, and directly relevant to the question — so it provides systematic, credible evidence for the perspective.

Limitation: even a strong study has limits — for example, it may focus on one country or population, so its findings may not generalise globally; or its sample, while sound, may be specific to a particular context.

Why both matter:

• Justifying alone would be uncritical — treating the study as beyond question.
• Acknowledging only the limitation would be needlessly dismissive of a strong source.
• Doing both shows the balanced, reasoned evaluation the mark scheme rewards, and lets the student weight the source appropriately: strong support, but applied with awareness of its scope.

A model sentence: "This peer-reviewed 2022 study offers credible, relevant evidence (justification), although its single-country focus limits how far it generalises (limitation), so I treat it as strong but not conclusive support."

The claim is mistaken, though it contains a grain of truth.

The grain of truth: identifying bias is good evaluation. A source with a vested interest (e.g. an industry body defending its product) may present a one-sided view, so its conclusions should be treated with caution. Spotting this through provenance is exactly what the mark scheme rewards.

Why 'useless' is wrong — three reasons:

1. A biased source still shows what a perspective argues. To represent a perspective fairly in the essay, you often need sources from within it — including interested ones. Excluding them can leave a perspective under-represented.
2. Its data may still be accurate. Bias is about slant, not necessarily falsity. A biased source's figures can be cross-checked (corroborated) against independent sources and used where they hold up.
3. Bias and reliability are different. An honest source can be unreliable (small or dated sample), while an interested source can present accurate data. Treating 'biased' as 'useless' confuses the two judgements.

How sources should actually be handled: evaluate every source systematically (credibility, provenance, relevance, bias), weigh the bias rather than applying a knock-out label, corroborate claims, and use the source with appropriate caution and weighting — clearly acknowledging its limitations in the text.

Judgement: the claim is wrong. Bias is a reason to calibrate trust, not to discard a source. The skilled essayist neither ignores a biased source nor accepts it uncritically, but evaluates it, weights it, and uses what is defensible — which is exactly what the AO1 source-evaluation marks reward.

Why it is a serious weakness:

1. It is one-sided. Evaluating only the opposing sources, while accepting your own uncritically, is motivated reasoning — it stacks the deck. The essay then cannot offer a balanced treatment of perspectives, which is required for the top bands.
2. It undermines the judgement. A reasoned judgement must rest on a fair contest between perspectives. If your own sources are never scrutinised, your conclusion looks predetermined rather than earned, weakening AO1.
3. It is poor scholarship. Examiner reports stress that students should evaluate every source, including supportive ones. Selective evaluation signals a lack of the critical, responsible disposition the qualification rewards.
4. It misses real weaknesses. Your own sources may have genuine limitations (vested interest, narrow sample, dated data) that, unexamined, leave your perspective looking stronger than the evidence warrants.

How to evaluate instead:

• Apply the same criteria (credibility, provenance, relevance, bias, currency, method) to all sources, regardless of which perspective they support.
• Acknowledge the limitations of your own best sources honestly, and weight them accordingly — using the two-halves pattern (appropriate because… although… so I treat it as…).
• Corroborate key claims on both sides against independent sources.
• Let the honest evaluation of your own sources feed the reflection (AO2) — e.g. recognising a limitation that made you less certain.

In short: even-handed, systematic evaluation of all sources is what makes the essay balanced and the judgement credible. Scrutinising only the other side is a transparent route to a capped, one-sided essay.
