✍️ Sample BCG Questions & Answers
1. Which practice best demonstrates correlation of evidence across multiple sources?
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?
Primary information is supplied by someone with firsthand knowledge of the event being recorded, regardless of when or where the record was created.

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 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.

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