In the third place, the evidence that the author provides is insufficient to support the conclusion drawn from it. One example is rarely sufficient to establisha general conclusion. Unless the arguer can show that A1 is representative of all A, the conclusion that B is completely unwarranted. In fact, in face of such limited evidence, it is fallacious to draw any conclusion at all.
In the fourth place, the argument has also committed a false analogy fallacy. The argument rests on the assumption that A is analogous to B in all respects, and the author assumes without justification that all things are equal, and that the background conditions have remained the same at different times or at different locations. No evidence is provided to support this assumption. However there are all kinds of important differences between . and other making the analogy highly less than valid. For example, A..., however, B....Thus lacking this assumption, the conclusion that is entirely unfounded.
Last but no least, the validity of the survey on which the argument relies is doubtful in itself. The survey cited by the author is too vague to be informative.
The claim does not indicate who conducted this survey and when and how the survey is conducted, neither does it mention what is the sample size, or how the samples are selected. Until these questions are answered the results of this survey are worthless as evidence to support that.
