Source Analysis and Evaluation of Historical Evidence
What you must understand
You need the vocabulary of source criticism: origin (author, date, place), purpose (why it was made), audience, form and genre, content (what it claims), and silences (what it omits). Distinguish primary from secondary sources and recognise that both require evaluation. Understand the difference between reliability (would this source mislead?) and usefulness (does it help answer this particular question?).
Traps
- Assuming a biased source is useless. A propaganda poster is unreliable about facts but highly useful about the regime's intentions and rhetoric.
- Judging reliability by whether you agree with the content. Reliability is about provenance and purpose, not agreement.
- Describing rather than evaluating. Quoting a source without analysing purpose earns little.
- Ignoring context. A speech's meaning depends on when, where, and to whom it was delivered.
- Treating visual or statistical sources as transparent. Both are constructed and require interrogation.
Worked example
Given a government decree nationalising land, ask: who wrote it, for whom, and what did it want them to believe? Then ask what it reveals unintentionally, such as the regime's need to legitimise itself or its anxiety about rural unrest. Conclude with a usefulness judgement tied to the question asked.
Rule of thumb
Use the origin–purpose–content–limit–value chain. Never finish with a limitation alone; always state what the source can still be used for.
