A new study reports that every U.S. president has had an IQ that placed him in the top two percent of the population: 138 or above. However, a different study focusing on leadership ability and potential concluded that the optimal IQ for a national leader is 125-above average, but not in the top two percent. Therefore, no United States president has had an IQ optimal for a national leader.
Which of the following, if true, most seriously weakens the conclusion above?
A. John F. Kennedy's IQ as reported in the second study was 127; in the first, 159.
B. A president's election in the US depends less on his leadership potential than on the public's perception of his intelligence.
C. Leadership ability in the second study was determined by studying the IQs of current national leaders from 100 different countries around the world.
D. The calculation of IQ is not an exact science; the margin of error can be as great as 3-4%.
E. IQ is only one of many factors that determines a national leader's success.
OA: A
