What common belief about ethics can lead to poor decision-making?

Choosing the belief that "if no one sees it, it's not wrong" highlights a common ethical trap where individuals may convince themselves that their actions are justifiable if they can avoid detection. This line of reasoning can lead to a slippery slope of unethical decisions, as it circumvents accountability and responsibility. With this mindset, individuals may engage in dishonest or harmful behaviors under the assumption that the absence of oversight absolves them of wrongdoing. It promotes a lack of integrity, suggesting that ethical behavior is contingent upon being observed rather than rooted in personal or societal principles.

In contrast, the other beliefs presented would not necessarily lead to poor decision-making in the same direct manner. The idea that everyone adheres to moral principles can reflect an optimistic view of human nature, while thinking that ethical standards are universally accepted ignores varying cultural norms but does not inherently encourage unethical behavior. The belief that ethics only apply to professionals may risk complacency regarding personal ethics, but it does not directly suggest that one's actions are permissible when unobserved.
