hasty generalization | a conclusion reached prematurely without sufficient evidence (look for stereotypes and prejudices or absolutes like "all", "everyone" or "no one") |
faulty use of authority | the arguer attempts to justify his claim by citing testimony or opinions of experts; arguer fails to acknowledge disagreements among experts or otherwise misrepresents trustworthiness/appropriateness of sources |
post hoc/ergo propter hoc | (doubtful cause) Latin = after this, therefore because of this; arguer asserts that because an event follows another event, it is therefore the cause of that event. |

false dilemma/either-or | arguer assumes that there are only two ways of looking at an issue |
slippery slope | arguer predicts that one thing will inevitably lead to another, and that one thing will be undesirable. Cause-and-effect error that relies on simplistic, erroneous connections |
begging the question | arguer makes an assertion as if she has already proven it but assertion lacks evidence |
straw man | a diversionary tactic in which the arguer attacks a view similar to but not the same as his opponents' view |
non sequitur | Latin = does not follow; arguer makes connections that are not logically related |
ad populum | Latin= to the people; an appeal to the prejudices of the masses; if many believe it, then it must be so. |
bandwagon effect | if something is popular or trendy, then it must be good |
red herring | fallacy in which the arguer throws out an unrelated argument to divert the reader's attention |
appeal to tradition | arguer asserts a course of action is correct because it's always been done that way |
faulty emotional appeals | arguer seeks sensational or sentimental reactions in the audience; bases argument on feelings to draw attention away from real issues |
