Historical Skills and Source Analysis
This domain tests method rather than content: appraising evidence, judging usefulness against a question, and separating what a source says from what it can support.
Core rules and concepts
- Provenance: establish author, date, audience, occasion and purpose before extracting content.
- Reliability is not usefulness. A propaganda poster is unreliable about conditions but excellent evidence of regime intentions. Tie every judgement to the specific enquiry.
- Intended versus unintended testimony: a factory inspector's report intends to document conditions but also reveals middle-class reformist assumptions.
- Corroboration: two independent sources agreeing is stronger than two derived from one origin; check whether one copied the other.
- Interrogate numbers: who was counted, what definition, what base, what incentive to misreport.
Worked example
Prompt: how useful are a factory inspector's report (1842) and a mill owner's memoir for studying child labour? Inspector: purpose is to justify regulation, so language is selected; value lies in technical detail about machinery and hours; limitation is the absence of children's own voices. Memoir: retrospective and self-justifying, but reveals the employer's mentalities and management reasoning. Judgment: useful for different questions - combine with wage books or testimony.
Traps
Equating 'biased' with 'worthless'. Assuming quantitative equals objective. Reading sources only for content while ignoring form, silence and audience. Treating one document as a window on an entire era rather than on a specific occasion.
