If the trainer is completely unsure and says something like, “There is a brown object on the left, but I don’t know what it is,” is there a best practice for the language to use in these cases, or is this sufficient?A. It is recommended that trainers clearly describe what they see and explain why they believe an object may be a certain thing, or why they are unsure or confused. Providing reasoning helps add clarity and context. For example: “I see the tail of an animal that may be a cat, but the rest of the body is hidden, so we cannot be certain.” “There is a brown object on the left, but it is blurry and partially outside the image, so we cannot determine exactly what it is.” This type of descriptive and explanatory language is considered best practice.
