People often do not make decisions by using the basic economic principle of rationally weighing all possibilities and then making the choice that can be expected to maximize benefits and minimize harm. Routinely, people process information in ways that are irrational in this sense.
Any of the following, if true, would provide evidence in support of the assertions above EXCEPT:

A.People tend to act on new information, independent of its perceived relative merit, rather than on information they already have.

B.People prefer a major risk taken voluntarily to a minor one that has been forced on them, even if they know that the voluntarily taken risk is statistically more dangerous.

C.People tend to take up potentially damaging habits even though they have clear evidence that their own peers as well as experts disapprove of such behavior.

D.People avoid situations in which they could become involved in accidents involving large numbers of people more than they do situations where single-victim accidents are possible, even though they realize that an accident is more likely in the latter situations than in the former.

E.(E) People usually give more weight to a physician’s opinion about the best treatment for a disease than they do to the opinion of a neighbor if they realize that the neighbor is not an expert in disease treatment.
