Decision makers tend to have distinctive styles. One such style is for the decision maker to seek the widest possible input from advisers and to explore alternatives while making up his or her mind. In fact, decision makers of this sort will often argue vigorously for a particular idea, emphasizing its strong points and downplaying its weaknesses, not because they actually believe in the idea but because they want to see if their real reservations about it are idiosyncratic or are held independently by their advisers.

Which one of the following is most strongly supported by the statement above?

(A) If certain decision makers’ statements are quoted accurately and at length, the content of the quote could nonetheless be greatly at variance with the decision eventually make.
(B) Certain decision makers do not know which ideas they do not really believe in until after they have presented a variety of ideas to their advisers
(C) If certain decision makers dismiss an idea out of hand, it must be because its weaknesses are more pronounced than any strong points it may have.
(D) Certain decision makers proceed in a way that makes it likely that they will frequently decide in favor of ideas in which they do not believe.
(E) If certain decision makers’ advisers know the actual beliefs of those they advise, those advisers will give better advice than they would if they did not know those beliefs.
