Of the case study examples shown in this module, which illustrates normalization of deviance?

• A. Case A
• B. Case B
• C. Case C
• D. All of the above

Answer: (D)

Normalization of deviance happens when a risky deviation from safety practices becomes accepted as normal because it hasn’t caused problems yet. People gradually adjust their behavior, procedures get bypassed, and safety margins shrink, often under the justification of saving time or improving efficiency. In the module’s case studies, each example shows this creeping shift: strict rules loosened, deviations treated as ordinary, near misses dismissed or rationalized, and management tolerating the practice until a warning or incident reveals the growing risk. Since all the cases illustrate this same pattern of growing tolerance for deviation, the best answer is that all of the above apply. Recognizing this pattern helps explain how small, repeated shortcuts can accumulate into a serious hazard if not challenged.
