Subadditivity effect
Description
The tendency to judge the probability of the whole to be less than the probabilities of the parts.
Example 1:
When estimating project costs, the sum of estimates for individual tasks might be perceived as less than an overall holistic estimate of the entire project, potentially leading to underestimation.
Example 2:
When estimating the total time to complete a project, a manager might estimate time for each individual task. The sum of these might be less than if they estimated the project as a whole, because they might overlook interdependencies or overheads.
