样本数量攻击 Another problem that seriously weaken the logic of this argument is that the survey cited is based on too small a sample to be reliable. Offered in support of the argument, the only evidence is that. Unless it can be shown that the sample is typical of all general group, the fact that is groundless for claiming that.
Loaded question和诚实性攻击 Whats more, the methodology of the survey is problematic for two reasons. For one thing, we are not informed whether the survey provided only 3 alternatives. If it did, the respondents, who might very well prefer another choice not provided in the survey, might be forced to give up their preferences. For another thing, we are not informed whether the survey response were anonymous or even confidential. If they were not, regardless of whether the responses were truthful, the respondents might supply responses favored by their superiors who might conduct the survey. Both events would lead this survey unreliable, let alone about drawing the conclusion that.
样本代表性攻击Moreover, a possible methodology problem in this argument is that of bias. At first place, the term so many is too vague to be statistically meaningful. Even if by so many the author means nearly all, perhaps workers who were more interested than others in the survey might be more likely to respond to the questionnairepossibly because they found the questionnaire more attractive. Lacking in the information about the number of workers surveyed and the number of respondents, it is impossible to assess the validity of the survey. For instance, if 1000 workers were surveyed but only 10 responded, the result should be highly suspect. Because the author fails to account for other interpretations such as this, the survey would be useless in concluding that.
