Certainty is a research area that focuses on understanding the various factors that influence an individual's confidence in their beliefs or decisions. This field explores how people assess probabilities, make judgments, and perceive certainty in uncertain situations. Researchers in this area seek to understand why people often overestimate or underestimate their level of certainty and how this impacts their decision-making processes. Additionally, studies in certainty research also examine the role of cognitive biases, emotions, and heuristics in shaping individual perceptions of certainty. Overall, the goal of this research area is to gain insights into how individuals navigate uncertainty and make informed decisions in various contexts.
