The Game is Afoot....
I expect to see a lot of logical fallacies between now and November, and I am planning on occasionally making fodder of certain poorly thought arguments.
I hope to help take some of the baby steps into beginning a new Age of Reason!
Here are a formal list (thanks to Wikipedia):
Formal fallacies are arguments that are fallacious due to an error in their form or technical structure. All formal fallacies are specific types of non sequiturs.
1. Appeal to probability: because something could happen, it is inevitable that it will happen. This is the premise on which Murphy's Law is based.
2. Argument from fallacy: if an argument for some conclusion is fallacious, then the conclusion must necessarily be false.
3. Bare assertion fallacy: premise in an argument is assumed to be true purely because it says that it is true.
4. Base rate fallacy: using weak evidence to make a probability judgment without taking into account known empirical statistics about the probability.
5. Conjunction fallacy: assumption that specific conditions are more probable than a single general one.
6. Correlative based fallacies
7. Denying the correlative: where attempts are made at introducing alternatives where there are none
8. Suppressed correlative: where a correlative is redefined so that one alternative is made impossible
9. Fallacy of necessity: a degree of unwarranted necessity is placed in the conclusion based on the necessity of one or more of its premises
10. False dilemma (false dichotomy): where two alternative statements are held to be the only possible options, when in reality there are several
11. If-by-whiskey: An answer that takes side of the questioner's suggestive question
12. Ignoratio elenchi (irrelevant conclusion or irrelevant thesis)
13. Homunculus fallacy: where a "middle-man" is used for explanation, this usually leads to regressive middle-man explanations without actually explaining the real nature of a function or a process
14. Masked man fallacy: the substitution of identical designators in a true statement can lead to a false one
15. Naturalistic fallacy: a fallacy that claims that if something is natural, then it is "good" or "right"
16. Nirvana fallacy: when solutions to problems are said not to be right because they are not perfect
17. Negative proof fallacy: that because a premise cannot be proven true, that premise must be false
18. Package-deal fallacy: when two or more things have been linked together by tradition or culture are said to stay that way forever
19. Propositional fallacies:
20. Affirming a disjunct: concluded that one logical disjunction must be false because the other disjunct is true.
21. Affirming the consequent: the antecedent in an indicative conditional is claimed to be true because the consequent is true. Has the form if A, then B; B, therefore A
22. Denying the antecedent: the consequent in an indicative conditional is claimed to be false because the antecedent is false; if A, then B; not A, therefore not B
23. Quantificational fallacies:
24. Existential fallacy: an argument has two universal premises and a particular conclusion, but the premises do not establish the truth of the conclusion
25. Illicit conversion: the invalid conclusion that because a statement is true, the inverse must be as well
26. Proof by example: where things are proved by giving an example
27. Syllogistic fallacies are logical fallacies that occur in syllogisms.
28. Affirmative conclusion from a negative premise
29. Fallacy of exclusive premises: a categorical syllogism that is invalid because both of its premises are negative
30. Fallacy of four terms: a categorical syllogism has four terms
31. Illicit major: a categorical syllogism that is invalid because its major term is undistributed in the major premise but distributed in the conclusion
32. Illicit minor: a categorical syllogism that is invalid because its minor term is undistributed in the minor premise but distributed in the conclusion.
33. Fallacy of the undistributed middle: the middle term in a categorical syllogism is not distributed
34. Categorical syllogism: an argument with a positive conclusion, but one or two negative premises
35. Informal fallacies are arguments that are fallacious for reasons other than structural ("formal") flaws.
36. Argument from repetition (argumentum ad nauseam)
37. Appeal to ridicule: a specific type of appeal to emotion where an argument is made by presenting the opponent's argument in a way that makes it appear ridiculous
38. Argument from ignorance ("appeal to ignorance")
39. Begging the question ("petitio principii"): where the conclusion of an argument is implicitly or explicitly assumed in one of the premises
40. Burden of proof
41. Circular cause and consequence
42. Continuum fallacy (fallacy of the beard)
43. Correlation does not imply causation (cum hoc ergo propter hoc)
44. Equivocation
45. Fallacies of distribution
46. Division: where one reasons logically that something true of a thing must also be true of all or some of its parts

49. Fallacy of the single cause
50. Historian's fallacy
51. False attribution

60. Moving the goalpost

64. Proof by verbosity (argumentum verbosium)
65. Psychologist's fallacy
66. Regression fallacy
67. Reification (hypostatization)
68. Retrospective determinism (it happened so it was bound to)
69. Special pleading: where a proponent of a position attempts to cite something as an exemption to a generally accepted rule or principle without justifying the exemption
70. Suppressed correlative: an argument which tries to redefine a correlative (two mutually exclusive options) so that one alternative encompasses the other, thus making one alternative impossible
