What term describes a person's beliefs about what is right or wrong?

The term that best describes a person's beliefs about what is right or wrong is "morals." Morals refer to principles or standards of behavior that guide an individual's understanding of right and wrong based on personal beliefs, cultural norms, and societal influences. Morals can vary widely among individuals due to different life experiences, cultural backgrounds, and individual reflections on ethical issues.

While "ethics" is related to the study of what is good for individuals and society and encompasses the systematic approach to determining right and wrong, it often applies to broader societal norms and professional standards rather than personal beliefs alone. "Legal" refers to laws established by governing bodies that dictate what is permissible or impermissible within a society, which is separate from individual beliefs. "Social" pertains to matters concerning society or groups of people and often involves collective norms and values but does not specifically address individual beliefs about right and wrong. Thus, when focused on personal beliefs directly, morals is the most precise term to use.
