People with high blood pressure are generally more nervous and anxious than are people who do not have high blood pressure. This fact shows that this particular combination of personality traits -- the so-called hypertensive personality -- is likely to cause a person with these traits to develop high blood pressure. The reasoning in the argument is most vulnerable to criticism on the ground that the argument ['focuses on nervousness and anxiety only, ignoring other personality traits that people with high blood pressure might have', 'takes a correlation between personality traits and high blood pressure as proof that the traits cause high blood pressure', 'simply restates the claim that there is a "hypertensive personality" without providing evidence to support that claim', 'presupposes that people have permanent personality traits']
