Historical Concepts and Skills
This domain tests how historians build knowledge: chronology, periodization, sourcing, contextualization, corroboration, and evidence-based argument. Expect questions that ask you to evaluate a document's origin and purpose, distinguish primary from secondary sources, or choose the best causal explanation.
Core rules
- Sourcing: identify author, audience, date, purpose, and bias before using a source. Bias does not make a source useless; it limits what claims it can support.
- Corroboration: compare independent sources. Agreement strengthens a claim; disagreement reveals perspective or error.
- Contextualization: place events in their own time; avoid presentism.
- Causation: distinguish long-term conditions, immediate triggers, and contributing factors. Correlation is not causation.
- Continuity and change: ask what changed, for whom, how fast, and what persisted.
Worked example
A 1912 memoir by a mill worker says children as young as ten worked twelve-hour shifts; a company payroll ledger lists workers by age but records few under fourteen. Which is more reliable for the number of child laborers? The ledger is stronger for counts if it is complete and unaltered, but it may underrecord because families lied about age or managers omitted names. The memoir is stronger for working conditions and perspective but weaker for precise numbers because memory and advocacy shape recall. Best answer: use the ledger for quantitative claims, the memoir for experience, and corroborate both with census records or factory inspection reports.
Traps
- Calling a later textbook 'primary' because it quotes documents.
- Rejecting a source solely because it is biased.
- Treating a date as a cause.
- Assuming change is always progress or immediate.
