The pseudocertainty effect is the belief that humans can fall victim to the belief that an outcome is certain while it is still uncertain. This frequently occurs during multistage decision-making processes (such as those that occur in business projects) where earlier decisions are sometimes discarded in favor of newer conclusions.
For example, in business a manager may take a calculated risk early on in the stages of a project. When the early risks are negated, he may then take greater calculated risks towards completion of the intended goal.
