Which of the following terms is used to describe a belief that is easily changed?

The term that describes a belief that is easily changed is "variable belief." This term conveys the idea that the belief is flexible and subject to change based on new information, experiences, or perspectives. In the context of public speaking and persuasion, understanding that a belief can be variable allows speakers to recognize opportunities to influence their audience effectively.

Fixed beliefs, on the other hand, are those that are resistant to change and often deeply rooted in one's identity or worldview. Altered beliefs imply that a belief has been changed, but do not specifically address how easily it can be changed. Modified beliefs suggest that a belief has undergone some sort of change or adjustment, yet again do not emphasize the ease of that change. Therefore, "variable belief" is the most accurate term for a belief that is changeable.
