I found a really good list of "debate fallacies," posted by Insin of TheAnimeLounge. Since most people who discuss politics here actively make at least one of these mistakes (including myself), I figured that this would be a nice reference:
Logical Fallacies
Be careful of committing some of these during debate. Recognizing them early can help prevent arguments from being totally unproductive. I have compiled a short list of popular fallacies for your reference. I hope this will help keep debates positive and not simply competitions of faulty rhetoric. I tried to simplify them as much as possible for quick viewing, see the examples if you want further clarification.
1) Straw Man: Creating a position for your opponent that is easier to argue against, but not necessarily a valid characterization. People do this to make it easier to attack others.
Examples of Straw Man -
"People who are very concerned about the environment value the lives of animals over people."
"Tony believes in evolution, so he thinks the world just happened magically by chance."
2) Slippery Slope: Accepting one stance means accepting an extreme version of that stance as well. It is does not take moderate views into account.
Examples of Slippery Slope -
"If we allow abortions to take place, eventually we will be killing newborn babies."
"If we allow American citizens to have guns, soon everyone will be shooting each other."
3) Ad Hominem: Attacking the person who made the argument, and not the argument itself.
Examples of Ad Hominem -
"The guy is prolife, there’s no way his views on abortion could be valid."
"ELK is a Canadian, what does he know about government?"
4) Appeal to Authority: This occurs whenever someone states a claim to be true because so-and-so said it was.
Example of Appeal to Authority -
"Hitman Reborn Forums are awesome, Heero the mod said so."
5) Appeal to Numbers/Popularity: These two are basically the same. They rely on heavy numbers or popular consensus to be evidence of a claim.
Examples of Appeal to Numbers/Popularity -
"Most people on the planet believe in some kind of higher power, therefore God must exist."
"A lot of people liked JFK, he must have been one of the best presidents in history. (actually, most of his presidency was marred by failure)"
6) SPECIAL PLEADING: Add a new equation to try and fix a failing question. This one is common in any religious debate.
Examples of Special Pleading -
"God is beyond our logic, therefore we cannot know."
"God works in mysterious ways."
"We cannot know God. (Usually this occurs whenever you have a debate some sort of religious proposition is shown to be illogical)"
7) Appeal to ignorance: Using what we don’t know as proof.
Example of appeal to ignorance -
"Life definitely exists out in space since it’s so big. (Well it’s true that it is a possibility, but the vastness of space is by no means definitive proof)"
8) Begging the Question: Essentially, this is assuming an answer.
Example of Begging the Question -
America must invest billions of dollars for a bailout, which will save the economy. (But will a bailout work, or help the economy? Perhaps, but it is not proved by that statement.)
9) Non Sequitur: The conclusion does not necessarily match the initial statement.
Examples of Non-Sequitur -
"America will come out of the recession because Obama is the man. (Maybe Obama is the man, but what if his game is off?)"
"We can’t fail, God is on our side. (God seems to be on everyone’s side)"
10) Post Hoc, ergo propter hoc: “It happened after, so it was caused by…”
Examples of Post Hoc, ergo propter hoc -
"When Bill Clinton went into office the economy got a lot better. (Perhaps Bill isn’t the only reason)"
"Insin decided not to go to the pre-semester get together, and after he declined 6 people also declined, therefore Insin not going turned a lot of people off. (Hopefully lol, but they were probably just busy too)"
11) Circular Argument: I think this one is self explanatory.
Example of Circular Argument -
"Religion is terrible, a lot of people are realizing how much crap it is, and since people are realizing how crappy religion is, it’s obvious that religion is terrible. (Yeah yeah, but why is it so terrible?)"
12) Excluded Middle: You essentially dichotomize everything and make it two extremes. I see this one a lot.
Example of Excluded Middle -
"If you aren’t with us, you are against us. Pretty simple."
