Values shape individuals' thinking and behavior through either instrumental or terminal values. Instrumental values are certain behaviors appropriate in all situations, while terminal values are enduring beliefs in attaining an end state. Values can stem from religion, philosophy, or family and become ingrained ways of behaving ritually or with politeness. Ethics involve studying moral obligations to distinguish right from wrong, and business ethics concern values management regarding right and wrong in the workplace, specifically regarding obvious mischief or moral mazes.
