60-second Quick Read
- Consistent results do not automatically mean a method is valid; a systematic bias can be reproduced very consistently.
- Strong investigations combine question-linked measurements, control of confounders, calibrated equipment, suitable repeats and a method another group can follow.
- Common trap: PPE does not make risk zero, and scientific value does not override animal welfare, consent, cultural protocols or heritage protections.
