Pseudoproof (Fallacy) |
|
There are encounters in arguments in which a reader will find material that may appear at first to be a proof but really is not a proof at all -- it is a pseudoproof, or what is commonly called a fallacy. Fallacies lead an audience astray, they distort and distract, they represent inadequate reasoning or nonreasoning, and they either exaggerate or oversimplify a claim instead of prooving it. |
| |
Fallacies in Logic Begging the Question |
|
No support is provided by the arguer who begs the question, and the claim is simply restated, over and over again, in one form or another. |
| |
Fallacies in Logic Red Herring |
|
A red herring provides irrelevant and misleading support that pulls the audience away from the real argument. |
| |
Fallacies in Logic Non Sequitur |
|
Non Sequitur in Latin for "it does not follow." In this type of fallacy, the conclusion does not follow from the evidence and the warrant. |
| |
Fallacies in Logic Straw Man |
|
A straw man involves attributing an argument to an opponent that the opponent never made and then refuting it in a devastating way. the arguer sets up an idea, refutes it, and appears to win, even though the idea may be unrelated to the issue being discussed. |
| |
Fallacies in Logic Stacked Evidence |
|
Stacking evidence to represent only one side of an issue that is clearly has two sides gives a distorted impression of the issue. |
| |
Fallacies in Logic Manufactured Evidence |
|
Using fake evidence to prove a claim will discredit an entire argument and ruin the reputation of the individual who makes it up. |
| |
Fallacies in Logic Unreliable or Insufficient Evidence |
|
Evidence should be verified, which means you should be able to look it up in another source and find the same information. There should also be enough evidence, and major information that could change the way one interprets the evidence should not be omitted. |
| |
Fallacies in Logic Exaggerated or Oversimplified Evidence |
|
Oversimplifying evidence can discredit an argument. |
| |
Fallacies in Logic Distorted Statistics |
|
Statistics can be manipulated or changed so that they appear to support a claim when. actually, they do not. |
| |
Fallacies in Logic Either-Or |
|
Some arguments are oversimplified by the arguer and presented as black-or-white, either-or choices when there are other alternatives. |
| |
Fallacies in Logic Post Hoc |
|
This is short for post hoc, ergo propter hoc, a Latin phrase that translates as "after this, therefore because of this." To put it more simply, post hoc is the fallacy of faulty cause. |
| |
Fallacies in Logic Hasty Generalization |
|
Sometimes arguers "jump to conclusions" by basing a conclusion on too few examples. |
| |
Fallacies That Affect Character or Ethos Ad Hominem |

| |
Ethical arguers |
