It appears that the probabilistic sciences of psychology and medicine teach their students to apply statistical and methodological rules to both scientific and everyday-life problems, whereas the nonprobabilistic science of chemistry and the nonscientific discipline of the law do not affect their students in these respects (p. 438)…. the luxury of not being confronted with messy problems that contain substantial uncertainty and a tangled web of causes means that chemistry does not teach some rules that are relevant to everyday life (p. 441).
