Question

Quizplus · Accepted Answer

Group A has a higher proportion of members who perform "bad" acts (30/90 = 1/3) than Group B (30/900 = 1/30). However, because the absolute number of "bad" acts is higher in Group B (300 vs. 30), people are more likely to evaluate Group B more negatively. This is because humans are relatively insensitive to probabilities and more sensitive to frequencies.
