✍️ Sample BCG Questions & Answers

1. Which practice best demonstrates correlation of evidence across multiple sources?
Comparing and analyzing all relevant evidence together to identify agreements, conflicts, and gaps

Correlation involves systematically comparing all relevant evidence to identify where sources agree, conflict, or leave gaps—essential for sound genealogical reasoning.

2. Which type of information is considered 'primary' in genealogical source evaluation?
Information provided by someone with firsthand knowledge of the event

Primary information is supplied by someone with firsthand knowledge of the event being recorded, regardless of when or where the record was created.

3. A genealogist prepares a proof summary rather than a proof argument. When is a proof summary appropriate?
When a simple, undisputed conclusion is supported by a single document

A proof summary is appropriate for straightforward conclusions supported by strong, consistent evidence that requires minimal explanation or conflict resolution.

4. How does the BCG's Genealogical Proof Standard apply specifically to genetic genealogy conclusions?
The GPS requires reasonably exhaustive research, complete citations, analysis of all evidence, resolution of conflicts, and a soundly reasoned written conclusion — applicable to DNA-based claims as well

The GPS applies universally; DNA-based genealogical conclusions must meet all five elements including exhaustive research, full citations, evidence correlation, conflict resolution, and a written proof argument.

5. Under BCG's ethical standards, a genealogist who discovers evidence that disproves a client's cherished family legend must:
Report findings honestly, including contradictory evidence

BCG's ethics require honest reporting of all findings, including evidence that contradicts the client's expectations or beliefs.

6. Which of the following scenarios represents a violation of BCG's standard for 'accurate citations'?
Citing a source from memory without verifying the details

Citing from memory without verification risks inaccuracy and is a direct violation of BCG's requirement for complete and accurate citations.
