amphiboly

Two grammatical word or phrase forms can be in different word groups, link to different pronouns, or be different speech parts {amphiboly}, an ambiguity fallacy.

composition fallacy

Extension to whole from part, or to class from individual, can have no logical basis {composition fallacy}|, an ambiguity fallacy.

decomposition fallacy

haec ergo quid fallacy

Thingness can differentiate thing from other things {haec ergo quid fallacy}. However, two things can share more similarities than differences. Thing natures can be general categories.

ignoring the base rate

Conditions have probabilities, such as 1% for diseases. Tests have reliability, such as 90%, and corresponding false-positive rates, such as 10%. If test is positive, most people think that chance of having condition is reliability, such as 90%, not probability divided by reliability, such as 0.9% {ignoring the base rate}.

misplaced concreteness

Wholes can be only one aspect {misplaced concreteness fallacy}|, an ambiguity fallacy. Part relations can be more important than part types.

scope fallacy

Words often have ambiguous scope or change scope after sentence rearranging or inference making {scope fallacy, logic}, an ambiguity fallacy. Statement, subject, or predicate negation changes scope. Reference change changes scope.

vagueness fallacy
