Systematic under- or over-estimation of general knowledge quantities is driven by specific cognitive biases.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Multiple studies demonstrate that systematic misestimations of quantities are driven by specific cognitive biases such as quantity insensitivity, attribute substitution, and operational momentum.

The analysis

The retrieved literature provides multiple specific empirical examples showing that systematic misestimations or under/over-estimations of quantities are tied to distinct cognitive biases (e.g., quantity insensitivity, operational momentum, heuristic-based attribute substitution). No papers refute this premise.

Paper [1] notes that human judgment features systematic cognitive biases causing underestimation of quantities, which can be counterbalanced by social influence.
