Keeping honest, traceable records
Objective: Explain why written records outperform memory, list the elements of a good record, and handle mistakes honestly.
Memory is unreliable, even for careful people. Details blur together after a few days, especially small ones like an exact amount, an exact time, or which container was which. A written record stays exactly as accurate as it was the moment you wrote it. Good records let you notice patterns you would otherwise miss, and they protect you from your own optimism: it is easy to remember a result as slightly better than it actually was.
A useful record includes the date, exactly what material was used and from which container or batch, the exact amounts and units, the conditions of the test, and what was observed, written in plain language at the time it happened rather than reconstructed afterward. It is worth recording things that seem obvious in the moment: room temperature, the time of day, whether anything unusual happened. You do not need special software; a plain notebook or spreadsheet, used consistently every time, beats an elaborate system used only occasionally.
Mistakes happen to everyone. The difference between a careful researcher and a careless one is how the mistake gets recorded. Write down what happened, plainly and without minimizing it. Do not erase or rewrite an earlier entry to make it look cleaner. If a number turns out to be wrong, add a note explaining the correction rather than deleting the original. An honest, if imperfect, record is far more useful later than a tidy one that quietly smooths over what actually happened.
Traceability means someone else could reconstruct what you did from your records: what arrived, from whom, under what documentation, what you prepared, and what you observed. Every container in your possession should carry the compound identity, lot, date prepared, concentration if in solution, and who prepared it. An unlabeled container is unusable material and should be documented and disposed of rather than guessed at.
- Traceability:
- The ability to connect a record, a sample, or a result back to a specific container, lot, date, and source.
