A Further Look at Blind Side Reading
In toxicologic pathology, “Blind Slide Reading” involves procedures in which the pathologist is unaware of the treatment group status of individual animals during the histologic slide evaluation phase of a toxicologic bioassay. Blind slide reading continues to be a controversial topic, despite published recommendations on this subject authored by professional societies and governmental regulatory agencies (e.g., The Society of Toxicologic Pathology and the USFDA). The reason for this is understandable.

From the earliest days of their careers, scientists and statisticians are cautioned repeatedly about the perils of sampling and observational bias, and correctly so, because it is undeniable that such factors have the potential to adversely impact study findings. Consequently, randomized sampling and blinding procedures have become axiomatic in contemporary scientific research, and experimental designs routinely incorporate such measures to varying degrees. More
