If new information contradicts earlier observations in a field note, what is the recommended action?

• A. Delete the old entry to avoid confusion.
• B. Treat the new information as separate and ignore the old.
• C. Document updates with dates, explain the reason for changes, and preserve original entries whenever possible.
• D. Immediately present the new information as sole basis.

Answer: (C)

When new information contradicts earlier observations, field notes should be updated transparently with dates, an explanation for the change, and the original entry preserved. This approach keeps the record complete and auditable, showing how understanding evolved over time and why conclusions were adjusted. Preserving the original entry while adding a dated update provides accountability and legal defensibility, so anyone reviewing the case can see both what was observed initially and what was later found, along with the rationale for the change. Deleting the old entry, treating the new information as separate, or presenting it as the sole basis disrupts the chronology and can undermine credibility and the integrity of the record.
