Advocates of group research raise several concerns regarding the visual inspection of data in single-subject designs. They argue that it may lack the sensitivity needed to detect weak treatment effects. Furthermore, visual inspection can be unreliable, as different researchers might interpret the same data differently. Finally, the overall judgments derived from visual inspection are difficult to efficiently summarize or compare across multiple studies.

Criticisms of Visual Inspection

Single-subject researchers address criticisms of visual inspection by emphasizing the steady state strategy and focusing on strong, consistent effects. If an effect is weak or data is noisy, they attempt to control extraneous variables rather than relying on statistical detection. If an effect remains difficult to detect visually, it is generally considered not strong or consistent enough to be practically significant.
