 Thresholds, however, can vary depending on the costs and benefits at stake in each case (see later discussion). So they need not be applied mechanically without considering the individual circumstances (Hedden and Colyvan 2019). Furthermore, if jurors are numerically literate, they should not lose sight of their humanizing function as they would no longer be intimated by numbers. So the worry suggests the need to ensure that jurors are numerically literate, not dispensing with probabilistic thresholds altogether.
