Faulty Analogy

You make a metaphorical comparison to your argument, and because the metaphor makes sense, you assume that the literal argument must also make sense.
Back
Tu quoque
Front
Latin for "you say": avoiding having to engage with criticism by turning it back on the accuser - answering criticism with criticism.
Person 1 to 2: "Your argument is invalid."
Person 2 to 1: "You make invalid arguments all of the time."

You only have a small, limited data set, but you make the assumption that it also applies on a larger scale.
Back
Denying the Antecedent
Front
This is very similar to the "false cause" fallacy, except we already know that A causes B. Then, you notice A didn't happen, so you assume that B must have never happened. (Maybe something else caused B.)
Back
Anecdotal
Front
Using a story (i. e. just one example) to assume something about the big picture on a much larger scale.
Back
No True Scotsman

In an argument, this is an attack on the person rather than on the opponent's ideas. It comes from the Latin meaning "turn to the man."
Back
Affirming the Consequent
Front
This is very similar to the "false cause" fallacy, except we already know that A causes B. Then, you notice B, so you assume that A must have happened. (Maybe something else could cause B.)
Back
Slippery Slope
Front
A fallacy that assumes that taking a first step will lead to subsequent steps that cannot be prevented.
Back
Red Herring
Front
A distraction from the topic at hand. It usually occurs when one side of the argument can't respond well, so they change the subject ever-so-slightly.
Back
Post Hoc Ergo Propter Hoc (False Cause)
Front
Latin for "after this therefore because of this." Arguing that because something follows something else it necessarily is the cause.
Back
Ambiguity
Front
An event or situation that may be interpreted in more than one way. Also, the manner of expression of such an event or situation may be ambiguous. Artful language may be ambiguous. Unintentional ambiguity is usually vagueness.
