Transcript of Logical Fallacies

designed by Péter Puklus for Prezi
Ad Hominem
:marked by or being an attack on an opponent's character rather than by an answer to the contentions made
: uses the manipulation of the recipient's emotions, rather than valid logic, to win an argument.
:adopting a popular point of view for the primary purpose of recognition and/or acceptance by others.
False Dilemma
:involving a situation in which limited alternatives are considered, when in fact there is at least one additional option.
Appeal to the people
:concluding a proposition to be true because many or most people believe it. "Ad populum"
Logical Fallacies
Appeal to Emotions
"If many believe so, it is so"
Red Herring
:a purposeful change in topic to distract from the original topic.
False cause
:arguing that two events that are correlated are assumed to have a causal connection.
Hasty Generalization
:reaching an inductive generalization based on insufficient evidence—essentially making a hasty conclusion without considering all of the variables
In other words, one event causes the other. This was one of the more common fallacies committed by ancient ancestors. During the last full moon, your dog died. Obviously the full moon killed your dog.
:when it is assumed that something is better or correct simply because it is older, traditional, or "always has been done."
Scare Tactic
: a strategy using fear to influence the public's reaction
"this is right because we've always done it this way."
