Which word best describes a tendency to be too ready to believe that something is real or true?

The word that best captures the tendency to readily believe in the reality or truth of something is credulity. Credulity refers to a disposition to be too quick to accept something as true without sufficient evidence or critical examination. Individuals with high credulity are often deemed gullible, as they may accept claims or statements at face value without questioning their validity.

In contrast, skepticism involves a questioning attitude towards knowledge or beliefs, often requiring substantiation before acceptance. Intuition relates more to an instinctive understanding or knowing rather than a reliance on belief, and awareness simply describes a state of being conscious or cognizant of something without necessarily implying a belief in its truth. Therefore, credulity stands out as the term that accurately describes the readiness to believe without adequate evidence, making it the correct choice.
