# Logical fallacy knowledge
## Fallacy Classification
1. Formal fallacy: incorrect reasoning that violates logical structure
2. Relevance fallacy: using irrelevant factors (emotion/personal/mass) to replace arguments
3. Improper Assumptions: Implicit Unverified Premises or Hypotheses
4. Fuzziness: logical discontinuity caused by linguistic ambiguity or conceptual confusion
5. Causation and Reasoning: Misattribution or Misunderstanding of Probability
6. Statistics and data: Improper use of data or sample bias
7. Appeal to: Using tradition/authority/nature/emotion as an alternative argument
8. Analogy and comparison: inappropriate analogies or double standards
9. Misrepresentation and misdirection: intentionally twisting an argument or diverting attention
## Logical fallacy table
| Serial number | Category | Fallacy name | Explanation | Example | | |
| ------ | ------------ | ------------ | -------------------------------------- | -------------------------------------------------------------------- | -- | -- |
| 1 | Improper assumption | Circular reasoning | The conclusion is the same as the premise, but it is not actually proved. | "The Bible is true because it says so in the Bible." | | |
| 2 | Improper assumptions | False dilemmas | Only two extreme options are provided, ignoring the possibilities in between. | "Either you support the war, or you are a coward!" (Ignoring peace talks) | | |
| 3 | Improper assumptions | Appeal to ignorance | Assuming something is true because it cannot be disproven. | "No one can prove that aliens don't exist, so aliens exist." | | |
| 4 | Improper Assumption | Begging the Question Fallacy | Implicitly implying the conclusion to be proved in the premise. | "Because he cheats, he is a dishonest person." ( "Cheating" already presupposes dishonesty) | | |
| 5 | Analogy and comparison | Mechanical analogy | Ignoring essential differences in analogies. | "The state is like a family, the government = the parent can monitor the citizens." (The nature of power is different) | | |
| 6 | Analogy and comparison | Double standards | Applying different standards to similar things. | "I was late because of traffic, but you were irresponsible for being late." | | |
| 7 | Analogy and comparison | False analogy | The objects of analogy lack comparability. | "Government surveillance is like parents caring for their children, so it is reasonable." (Different power relations) | | |
| 8 | Ambiguity | Substituting concepts | Secretly changing the meaning of terms. | "Freedom = doing whatever you want, so freedom is dangerous." (originally referring to political freedom) | | |
| 9 | Ambiguity | Abuse of metaphor | Using metaphors instead of arguments. | "The market is like a battlefield, it must be monopolized!" (The logic of the battlefield and the market has nothing to do with each other) | | |
| 10 | Vagueness | Ambiguity fallacy | Using the polysemy of a word to mislead an argument. | "A feather is light, and the antonym of light is heavy, so a feather is heavy." | | |
| 11 | Distortion and misleading | Straw man fallacy | Distorting the other party's argument and then refuting it. | A: "Military spending should be reduced." B: "Do you want your country to be at the mercy of others?" | | |
| 12 | Misinterpretation and misleading | Generalizing | Using a partial case to generalize the whole. | "There was a robbery in a certain place, so the public security there is very bad." (Ignoring the overall crime rate) | | |
| 13 | Distortion and misleading | Changing the subject | Avoiding the original point and introducing irrelevant content. | A: "The government should improve medical care." B: "The economy is the key!" | | |
| 14 | Misinterpretation and misleading | Taking a sentence out of context | Taking a passage and distorting the original meaning. | "Confucius said 'repay evil with virtue', so we should forgive unconditionally." (The second half of the original sentence emphasizes "how to repay virtue" ) | | |
| 15 | Misinterpretation and misleading | False correlation | Mistaking coincidental association for causation. | "Drownings increase when ice cream sales increase, so ice cream causes drownings." (actually due to high temperatures) | | |
| 16 | Appeal to category | Appeal to tradition | Claiming that something is justified because it has always been this way . | "Marriage must be between one man and one woman because it has been this way since ancient times." | | |
| 17 | Appeal to category | Appeal to nature | Think "natural is good" . | "Natural herbs are absolutely harmless!" (Ignore toxicity) | | |
| 18 | Appeal to type | Appeal to authority | Use authoritative opinions to replace arguments. | "An expert said that vaccines are harmful, so vaccines are harmful." (Unverified evidence) | | |
| 19 | Appeal to type | Appeal to emotion | Use strong emotions instead of arguments. | "Don't support environmental protection? Do you want your children to live in pollution?" | | |
| 20 | Statistics and Data | Hasty Generalizations | Generalizing the whole from a very small sample. | "The three doctors I know all smoke, so all doctors smoke." | | |
| 21 | Statistics and Data | Data Manipulation | Selective use of data to mislead. | "Product positive rating 99%!" (Only 1 negative review out of 10 is shown) | | |
| 22 | Statistics and Data | Survivorship Bias | Focusing only on "surviving" data and ignoring failure cases. | "Bill Gates dropped out of school and succeeded, so studying is useless." (Ignoring most failures) | | |
| 23 | Statistics and Data | Base Rate Ignorance | Ignoring the base probability and exaggerating the significance of individual cases. | "A certain drug has an 80% cure rate, but the patient's own recovery rate is 90%, so it is actually ineffective." | | |
| 24 | Correlation Fallacy | Appeal to pity | Using sympathy instead of logical argument. | "I failed the test, but my mother will be sad, please give me a pass!" | | |
| 25 | Correlation Fallacy | Appeal to fear | Using threats or intimidation to support an argument. | "Without insurance, your house will catch fire!" | | |
| 26 | Relevance Fallacy | Ad hominem | Attacking the person's character rather than his argument. | "He has a low level of education, so his opinion is not worth mentioning." | | |
| 27 | Correlation fallacy | Appeal to the masses | Because the majority agree, it is considered correct. | "90% of people believe in horoscopes, so horoscopes are true." | | |
| 28 | Formal fallacy | Denial of the antecedent | Mistakenly assuming that "if A then B, not A then not B" is true. | "If it rains, the ground will be wet; it is not raining now, so the ground is not wet." (Ignore the sprinkler) | | |
| 29 | Formal fallacy | Affirmation of the consequent | Falsely assuming that "if A then B, B then A" is true. | "If you have a fever, you will have a headache; now you have a headache, so you must have a fever." (Ignore other reasons) | | |
| 30 | Formal Fallacy | Fallacy of Composition | Falsely assuming that properties of a part necessarily belong to the whole. | "Each brick is light, so the building is light." | | |
| 31 | Formal fallacy | Decomposition fallacy | The mistaken assumption that the properties of the whole must belong to the parts. | "The Chinese team is strong, so each player is strong." | | |
| 32 | Causation and Reasoning | Slippery Slope Fallacy | Assumption A will lead to extreme consequence Z, lacking intermediate logic. | "Allowing same-sex marriage will lead to human-animal marriage next!" | | |
| 33 | Causation and Reasoning | Gambler's Fallacy | Mistaking the probabilities of independent events for mutual influence. | "If the number comes up high five times in a row, the next number will definitely come up low!" (Dice have no memory) | | |
| 34 | Causation and Reasoning | Causal Confusion | Confusion of cause and effect order or correlation. | "Teams wearing red have a higher chance of winning, so red brings victory." (Ignoring team strength) | | |
| 35 | Causation and Reasoning | Post hoc fallacy | Because A happened before B, we assume that A caused B. | "The cockcrow leads to the sunrise, so the cockcrow leads to the sunrise." | | |
