a conclusion that something is absolutely true
Original Dramatica Definition
The character representing the Certainty characteristic is not a risk taker. It must be completely sure before it takes action or accepts information as true. The slightest potential for error or change will stop it in its tracks. On the plus side, it never goes out on a limb far enough to break it; on the minus side, it might never get out far enough to get the fruit either. Many opportunities are lost to it because it hesitates until it is too late.
syn. sureness, definiteness, having no doubts, total reliability, indisputability, irrefutability, unmistakability, certitude, conviction
