Red herring - divert attention, it's about subtly leading off the track Differentiating between red herring and the straw man. Look at the way they distract: Straw man distorts original argument then knocks down the new distorted argument Red herring leads away from argument and changes the subject In effect see if the argument was distorted (straw man) or the subject changed (red herring) Also: straw man usually needs 2 arguers. Red herring doesn’t always need one. The missing point does not create any new premises. The other 2 does. The missing points fallacies conclusion comes from the original premises involved. Missing points conclusion is irrelevant. The other 2s conclusions are relevant to the fallacious premises they set up. Fallacies of weak induction Appeal to unqualified authority Appeal to ignorance - lack of proof taken as proof of lacking Exception :- when a group of experts in a field say Exception :- when a group of experts in a field say something could not be found, then it probably doesn't exist. Hasty Generalization - occurs when sample doesn't reasonably portray the whole group or the sample size too relatively small. False Cause - the link between premises and conclusion depends on imagined causal connection that probably does not exist a.
