The study determined the following IQs of each president as accurate to within five percentage points:
147 Franklin D. Roosevelt (D) 132 Harry Truman (D) 122 Dwight D. Eisenhower (R) 174 John F. Kennedy (D) 126 Lyndon B. Johnson (D) 155 Richard M. Nixon (R) 121 Gerald Ford (R) 175 James E. Carter (D) 105 Ronald Reagan (R) 098 George HW Bush (R) 182 William J. Clinton (D) 091 George W. Bush (R)
低くなった理由は、 President Bush was rated low because of his inability to command the English language, his lack of any scholarly achievements, and an absence of anything authored by him that would reflect an intellectual effort
A recent think tank study of presidential I.Q.'s from the 40's to the present leads one to believe that Bush might have some difficulty writing out his name and address and talking on the phone at the same time.
