When I was reading B, I thought that if he took anything granted, why was he even surveying? Even if he takes anything for granted, he will make a definite conclusion from the survey when it matches with his assumption. Since he didn't make a strong solid conclusion from the survey, I think he didn't take anything for granted.

The psychologist’s argument is most vulnerable to criticism on which of the following grounds?

A. It fails to adequately address the possibility that many of the volunteers may not have understood what the psychological questionnaire was designed to measure.
even if peopl dont what the survey is for, it doesnot impact their answers

B. It takes for granted that the volunteers with the highest levels of self-esteem had better social skills than did the other volunteers, even before the former volunteers had attained their high levels of self-esteem.
already the argumnt has mentioned that high esteem people took the test.

C. It overlooks the possibility that people with very high levels of self-esteem may tend to have a less accurate perception of the strength of their own social skills than do people with moderate levels of self-esteem.
this could be possible

D. It relies on evidence from a group of volunteers that is too small to provide any support for any inferences regarding people in general.
size of group is irrelevant

E. It overlooks the possibility that factors other than level of self-esteem may be of much greater importance in determining the strength of one’s social skills
argument is concerned abt social skill and self esteem relationship, other things out of scope.

Official Answer:

Argument Evaluation

Situation In a psychological study of 100 volunteers, those found to have the highest self-esteem consistently rated themselves as having much better social skills than did those found to have moderate self-esteem.

Reasoning What is wrong with the psychologist citing the study’s results to justify the conclusion that exceptionally high self-esteem greatly improves social skills? The psychologist reasons that the study shows a correlation between very high self-esteem and how highly one rates one’s social skills, and that this correlation in turn suggests that very high self-esteem improves social skills. This argument is vulnerable to at least two criticisms: First, the argument assumes that the volunteers’ ratings of their own social skills are generally accurate. But very high self-esteem might in many cases result from a tendency to overestimate oneself and one’s skills, including one’s social skills. Second, the argument fails to address the possibility that good social skills promote high self-esteem rather than vice versa, as well as the possibility that some third factor (such as a sunny disposition or fortunate circumstances) promotes both high self-esteem and good social skills.

Quote:
A. It fails to adequately address the possibility that many of the volunteers may not have understood what the psychological questionnaire was designed to measure.

A - An experiment’s subjects do not have to understand the experiment’s design in order for the experimental results to be accurate.

Quote:
B. It takes for granted that the volunteers with the highest levels of self-esteem had better social skills than did the other volunteers, even before the former volunteers had attained their high levels of self-esteem.

B - To the contrary, the argument concludes that the volunteers with the highest self-esteem attained their enhanced social skills as a result of attaining such high self-esteem.

Quote:
C. It overlooks the possibility that people with very high levels of self-esteem may tend to have a less accurate perception of the strength of their own social skills than do people with moderate levels of self-esteem.

C - Correct. - As explained above, very high self-esteem may often result from a tendency to overestimate oneself in general, and thus to overestimate one’s social skills.

Quote:
D. It relies on evidence from a group of volunteers that is too small to provide any support for any inferences regarding people in general.

D - A group of 100 volunteers is large enough for an experiment to provide at least a little support for at least some inferences regarding people in general.

Quote:
E. It overlooks the possibility that factors other than level of self-esteem may be of much greater importance in determining the strength of one’s social skills.

E - As explained above, the argument overlooks the possibility that some third factor may play a significant role in determining the strength of one’s social skills. But even if some factor other than self-esteem is more important in determining the strength of social skills, that would still be compatible with very high self-esteem being of some importance in improving one’s social skills.

The correct answer is C.

Here is a simple explanation to all the folks confused with Option B -

GMATNinja as usual has given us an awesome explanation. I would like to add a few points to it!

Quote:
Psychologist: In a study, researchers gave 100 volunteers a psychological questionnaire designed to measure their self-esteem. The researchers then asked each volunteer to rate the strength of his or her own social skills. The volunteers with the highest levels of self-esteem consistently rated themselves as having much better social skills than did the volunteers with moderate levels. This suggests that attaining an exceptionally high level of self-esteem greatly improves one’s social skills.



Read the conclusion slowly " This suggests that attaining an exceptionally high level of self-esteem greatly improves one’s social skills. "
The psychologists say that high self esteem improves the social skills.


Quote:
B. It takes for granted that the volunteers with the highest levels of self-esteem had better social skills than did the other volunteers, even before the former volunteers had attained their high levels of self-esteem.


Now read option B slowly. In simple words it says "People with high self esteem already had better social skills (than other volunteers with low self esteem) even before they attained their highest level of self esteem."
Even if this were true it does not really make the argument vulnerable to criticism. Why?
Because even if they had better social skills earlier, there is still scope for improvement in their social skills which may be caused due to high levels of self esteem.
Even if volunteers with high self esteem had better social skills (than other volunteers with low self esteem) before they reached high levels of self esteem, it does not really make the argument vulnerable. Because it might be that these volunteers made their social skills even better than before. Which means they improved their social skills. Just what the conclusion says.

GMATNinja please let me know if my approach is 'vulnerable to criticism'.
