Consists of a consideration of only the two extremes when there are one or more intermediate possibilities. ("AP calculus BC class in impossible; either you get it or you don't)
Deliberately leading to a conclusion by providing insufficient, selective evidence.( "Ping-pong is a dangerous sport; my friend got hit in the eye with the ball and almost lost her vision in that eye.")
Based on the assumption that whatever has not been proven false must be true (or, similarly, whatever has not been proven true must be false) ("No one can prove the existence of the Loch Ness Monster; therefore it exists." Or, "No one can prove that the Loch-Ness monster exists, therefore the Loch-Ness monster does not exist.)
Refers to the (sometimes unintentional) setting up of a cause-and-effect relationship when none exists. One event can happen after another without the first necessarily being the direct cause of the second. "Violent crime among adolescents has risen int he past decade, and that is the result of increased sales of violent video games."
Tempts us to agree with the writer's assumptions based on the authority of a famous person or entity or on his or her own character (when the writers are well known) "This is absolutely awesome - it's the best review book ever written." -Shakira
"It doesn't follow". A statement that does not relate logically to what comes before it. There is no logical connection between the initial phrase and the one that follows it. "If you really watned to earn a 5 on the AP English test, you wouldn't spend so much time reading Isabella Allende's novels."
5 True/False Question
Equivocation → Does not allow for discussion because the speakers presumes that his or her beliefs are beyond question; essentially, the "logic" is, "I'm correct because I'm correct." "We are members of the Wombat party and, as such, know that we are right when we assert that Wombats are the best!"
Dogmatism → Does not allow for discussion because the speakers presumes that his or her beliefs are beyond question; essentially, the "logic" is, "I'm correct because I'm correct." "We are members of the Wombat party and, as such, know that we are right when we assert that Wombats are the best!"
Sentimental Appeals → Attempts to appeal to the hearts of readers/listeners so that they forget to use their minds. Not a valid argument, but it works sometimes.
Bandwagon Appeals → Otherwise known as peer pressure, this type of argument encourages the listener to agree with a position because everyone else does. "If everyone else is doing it, it must be alright." The speaker usually tries to avoid having to explain the merits of the issue and explain why the ban is inappropriate.
Ad Hominem → Attempts to shift attention away from an important issue by introducing an issue that has no logical connection to the discussion at hand. Similar to a sentimental appeal, but the speaker is still appealing to minds rather than sentiments.
