Skepticism

Skepticism was an attitude of doubting that claims, beliefs or statements were true or that something would actually happen. An individual was known as a skeptic.

In 2366, while talking to a grey-haired man about his experience, Liko said to him, "I understand your skepticism. Had it not happened to me, I would find it difficult to accept as well." (TNG: "Who Watches The Watchers")
