Slanting

This error occurs when the issue is not treated fairly because of misrepresenting the evidence by, say, suppressing part of it, or misconstruing some of it, or simply lying. See the following fallacies: Lying, Misrepresentation, Questionable Premise, Quoting out of Context, Straw Man, Suppressed Evidence.

Questionable Premise

If you have sufficient background information to know that a premise is questionable or unlikely to be acceptable, then you commit this fallacy if you accept an argument based on that premise. This broad category of fallacies of argumentation includes appeal to authority, false dilemma, inconsistency, lying, stacking the deck, straw man, suppressed evidence, and many others.

Lying

A fallacy of reasoning that depends on intentionally saying something that is known to be false. If the lying occurs in an argument's premise, then it is an example of the fallacy of questionable premise.

Example:

Abraham Lincoln, Theodore Roosevelt, and John Kennedy were assassinated.
They were U.S. presidents.
Therefore, at least three U.S. presidents have been assassinated.
Roosevelt was never assassinated.
