Overview:The psychologist argues that people should not necessarily try to rid themselves of a tendency to make cognitive errors of a certain type. This conclusion is supported by a comparison to the undesirability of ridding themselves of a tendency toward a certain type of visual error. Your task is to find the answer choice that describes how this argument works.
The Correct Answer:C The argument does what (C) describes. It argues that an action (trying to overcome our tendency to make certain cognitive errors when making predictions about future happiness) might not be appropriate. And it argues for this by presenting a situation that is analogous in that it also concerns a tendency toward error—the error of perceiving lines that are actually parallel as if they converge. Having surgery to change our tendency to misperceive parallel lines in this situation corresponds to trying to overcome our tendency to make cognitive errors. And the argument suggests that having this surgery is not appropriate.
The Incorrect Answer Choices:A The argument does not claim that any particular event is inevitable. It does claim that we tend to make certain kinds of errors, but it doesn’t claim that we inevitably make those errors. Even in the visual context, the argument only claims that parallel lines
often appear to converge.
B The only thing the argument attempts to undermine is the view that people should try to rid themselves of their tendency to make certain cognitive errors, but it's not accurate to consider this view a theory. Moreover, the argument does not refer to, much less call into question, any assumption on which this view is based, so the argument cannot be said to do what (B) describes.
D The psychologist doesn't actually argue that the two situations (the tendency to make certain cognitive errors and the tendency to make a particular visual error) are similar. The psychologist's argument merely assumes that they are similar in certain respects. Moreover, the psychologist's argument does not try to establish that the same action would be reasonable in each situation. It asserts that the action would not be reasonable in the case of the visual error and argues that the corresponding action would not be reasonable in the case of the cognitive errors.
E The psychologist does argue against a particular action (trying to get rid of a tendency to make certain cognitive errors) but the psychologist's argument does not use a generalization to do so. Instead, it compares that particular action to a different particular action (having surgery). Hence the argument does not do what (E) describes.
