Rokeach argued there is a limit to the number of terminal values, as these are based on human biological and social needs. However, he suggested there could be many instrumental values used to attain the terminal values. In his research, Rokeach defined 18 terminal values: Freedom, Happiness, Mature Love, Self-Respect, True Friendship, Inner Harmony, Family Security, Wisdom, A Sense of Accomplishment, Equality, An Exciting Life, A World at Peace, A Comfortable Life, Pleasure, A World of Beauty, Social Recognition, National Security, and Salvation. Such values as Honesty, Responsibility, Ambition, Independence, and Affection are listed as instrumental values. Interestingly, when one thinks of “values” these are the ones most often referenced since they directly relate to behavior and decision-making.
