Which guideline is important when taking field notes?

Recording all information in ink is essential because it ensures the permanence and integrity of the notes taken during an incident or observation. Ink is less likely to smudge or fade over time compared to pencil or other non-permanent writing instruments, which can become illegible. This is particularly important in the context of field notes that may be used as evidence in legal situations or for official reports, where the accuracy and reliability of the documentation are critical.

Using ink also helps maintain a professional standard in record-keeping that can be scrutinized during investigations or reviews. Clear, permanent notes are more reliable and contribute to a stronger case when necessary. While using colored pens or different notebooks may seem useful for organization, they do not offer the same level of permanence and legality that ink does, which is why this guideline is prioritized.
