Surely my high school physics teacher is not as smart as Einstein. We know this from the fact that the writings of the Mayan religious scribes exhibit a high degree of mathematical competence. Fallacy of false analogythe mistake of using an argument from analogy in which the basic similarity is not relevant or in which there are relevant dissimilarities between the basic and inferred analogs.

Clarifying an argument from analogy is usually a straightforward matter. Therefore, God exists. In each case, the arguer tries to use the lack of evidence as support for a positive claim about the truth of a conclusion. Often, the arguer never returns to the original issue. not only beautiful, she was tough, smart, and just a bit cocky.

Like any validity counterexample, the reasoning can be represented as an argument from analogy, clarified as follows: Here the relevance of the similarity depends on a deductive background argument; for the way to argue that a certain form (the basic similarity) is invalid (the inferred similarity) is by use of this valid affirming the antecedent argument, which has a self-evidently true first premise: In this case, the logical strength of the analogical argument is borrowed from a sound deduction.

The arguer uses a potentially ambiguous term in more than one sense and consequently misleads the reader. The second part of the total evidence condition for frequency arguments operates the same way. The argument is logically weaker to the extent that it fails in either area.
