Definition:Individual offered as evidence, solely based on reputation

OR

Individual offered as expert is not an expert on the issue in dispute





Definition:Shifts the meaning of a word or phrase in a single argument





Definition:Make a claim from a sample that is too small or in someway unrepresentative of target population






Definition:Compares two or more things that are not in essence similar and suggests that since they share certain characteristics, they share others as well






Definition:Conclusion of argument is hidden amongst its assumptions—assumes that very question being argued has already been proven






Definition:Shift attention from the merits of the argument to the source or origin of the argument






Definition:Directly or implicitly threatening the audience






Definition:Attack a view similar to but not the same as the one your opponent holds, a diversionary tactic





15. Appeal to Authority16. Appeal to Fear

Definition:Judges and labels the same act differently depending on the person or group who performs the act






Definition:Contrary possibilities are wrongly presented as though they are exhaustive and exclusive—either/or reasoning






Definition:Irrelevant topic is presented in order to divert attention from the original issue






Definition:Discredits an argument because the behavior of the person proposing it does not conform to the position s/he’s holding






Definition:A simplistic and improbably prediction based on series of steps






Definition:Because one event follows another event, the first event must be the cause of the second—false cause






Definition:The claim (conclusion) does not follow the premises (reasons)—it is irrelevant

Reminder:

The difference between post hoc and non sequitur fallacies is that, whereas the post hoc fallacy is due to lack of

causal connection, in the non sequitur fallacy, the error is due to lack of

logical connection.
