Examples include:
Ad Hominem - attacks the person rather than the issue in dispute (character attacks unrelated to the issue).
Non Sequitur (Red Herring) - introduces an irrelevant issue to divert our attention from the subject of discussion.
Bandwagon - attempt to prove a claim is correct by arguing that most people agree.
False Authority - testimony from people with no real expertise.
Either/Or - forces a choice between two alternatives when more than two alternative exist.
Slippery Slope - objects to something not because it is undesirable, but because it could lead to something else undesirable; taking that first step could lead to subsequent steps that can’t be avoided.
