During an accident investigation, Officer Cox displayed which attitude by denying wrongdoing?

The displayed attitude of denying wrongdoing during an accident investigation aligns closely with self-righteousness. This attitude reflects a belief that one is morally superior or justified in their actions, often leading individuals to reject accountability or the possibility that they could be at fault. Such a mindset can impede effective investigation and resolution of the situation, as it fosters an unwillingness to acknowledge mistakes or misjudgments.

In contrast, over-confidence typically manifests as an unwarranted assurance in one's abilities or understanding, but it does not inherently involve a rejection of wrongdoing. Impatience is more about the desire to expedite a process and is less related to accountability. Ignorance denotes a lack of knowledge or awareness regarding a situation, rather than an explicit denial of fault. Thus, self-righteousness aptly captures the essence of Officer Cox’s attitude in this scenario.
