Strawman - misrepresenting an argument to make it easier to attack
False cause - relationship is not causation
Appeal to emotion - appeal to fear, envy, hatred, pity, or pride
Fallacy fallacy - a poor argument does not make something wrong
Slippery slope - use of extreme hypotheticals
Ad hominem - attack character or personality instead of argument
Tu quoque ("too-kwo-kee") - answer criticism with criticism of accuser
Personal incredulity - not understanding does not make something wrong
Special pleading - move the goalposts when original claim is shown to be false
Loaded question - build misleading presumption into query
Burden of proof - shifting argument to something else that cannot be disproven
Ambiguity - use double meaning to mislead or misrepresent
Gambler's fallacy - assume there's a connection to disconnected events, like a hot streak
Bandwagon - plea to popularity for validation
Appeal to authority - use person or institution or power for validation
Composition / division - assume whole is representative or parts (or vice versa!)
No true Scotsman - appeal to purity
Genetic - assumptions based on where (or who!) something came from
Black or white - assumptions based on only two options when many options exist
Begging the question - circular argument containing the conclusion in the premise
Appeal to nature - assumptions based on natural being justifiable or better
Anecdotal - using an isolated example instead of a sound argument or compelling evidence
Texas sharpshooter - cherry picking data to support a pattern or argument
Middle ground - assumptions that a compromise or middle point between extremes must be the truth
You forgot the "Everybody does it and they are worse" logical fallacy. It's by far the most common.
"Everybody does it" is an appeal to authority.
This is also an awesome list for evil politicians--the fallacies exist because (sadly) they work!
I did realize as I was posting this, that it could be used as a handy "how to" guide.
My hope is that this is used for good: people know the tricks so they can avoid being influenced by the tricks.
