Handwriting analysis—also known as graphology—is a poor way to predict personality types, even though it is used by 3,000 United States firms and by a majority of European companies. In a recent study, five graphologists scored no better than chance in predicting the occupations of forty professionals.
Which one of the following is an assumption necessary to the argument?
(A) People in the same occupation usually do not have the same personality type. - WRONG. Even if they had then it makes no sense as to how personality is predicted. All in all this has no impact as such.
(B) Graphology is an effective means of predicting personality types
in non-business contexts. - WRONG. Again no impact.
(C) There are more United States firms that do not use graphology than all the United States and European firms that do use it. - WRONG. Out of Scope.
(D) There are several other techniques for predicting personality types that are more accurate than graphology. - WRONG. Again how does that make the conclusion stand more strongly. It might be the case here that others are better but the reasoning offered against the conclusion is not impacted.
(E) There is a correspondence between type of personality and choice of occupation. - CORRECT. If there is none then we are in trouble. Then any analysis is bound to be poor.
Answer E.
