Final answer:
The technique of neutralization used when deviance is perceived as not causing harm is the 'denial of injury.' This rationalizes deviant behavior by claiming no one was harmed.
Step-by-step explanation:
When deviance is perceived to not cause injury or harm to anyone, it employs the technique of neutralization known as denial of injury. This is one of several techniques identified by Sykes and Matza in their study on juvenile delinquency. Individuals using this technique might rationalize their behavior by asserting that their actions are not problematic since they did not result in any apparent harm, as in the rationale "Nobody got hurt, so what's the big deal?" This approach minimizes the perceived consequences of the deviant action.
