Which of the following refers to a form of human motivation whereby our decisions and actions are motivated primarily (if not exclusively) by our own interests?

A. Egoism
B. Psychological determination
C. Altruism
D. Ethnocentrism

Is it A?

Yes.

Yes, you are correct. The term that refers to a form of human motivation whereby decisions and actions are primarily driven by our own interests is A. Egoism.

To arrive at this answer, let's break down the options:

A. Egoism: This term refers to the belief that individuals act primarily out of self-interest.

B. Psychological determination: This term is not directly related to motivation or self-interest. Psychological determination is the concept that our thoughts, feelings, and behaviors are determined by psychological factors.

C. Altruism: Altruism is the belief in, or practice of, selfless concern for the well-being of others. It is the opposite of egoism, as altruistic individuals prioritize the welfare of others over their own self-interest.

D. Ethnocentrism: Ethnocentrism is the belief in the superiority of one's own cultural or ethnic group. While it involves a bias towards one's own group, it is not directly related to personal motivation based on self-interest.

By considering the definitions of each option, we can conclude that option A, Egoism, is the most fitting answer for the question.
