Which of the following is a common sign of someone engaged in shoplifting behavior?

The correct response highlights that not looking at the item when selecting can indeed be a common sign of someone engaged in shoplifting behavior. This behavior may suggest that the individual is distracted, anxious, or trying to avoid drawing attention to their actions. In this context, it reflects a lack of confidence in their choice, as they may be focused on the environment around them rather than on the product itself. This suspicion can arise because some individuals who are planning to shoplift will often avoid drawing attention to their actions by minimizing their engagement with the merchandise.

In contrast, excessive eye contact, talking loudly, or attempting to pay for items too quickly may not reliably indicate shoplifting. In certain situations, these behaviors could actually result from normal shopping habits or further efforts to divert attention from suspicious actions. Understanding these subtle signs can help in identifying potential shoplifters, making it important to focus on the behavior that most directly suggests avoidance of scrutiny, such as not looking at the item being selected.
