Lying with Statistics

Using true figures and numbers to "prove" unrelated claims. "College tuition costs have actually never been lower. When taken as a percentage of the nation debt, the cost of getting a college education is actually far lower today than it was in 1965!"

Transfer

a corrupt argument hat falsely associates a famous person or thing with an unrelated standpoint. (Putting a picture of Dr. Martin Luther King Jr. on an advertisement for mattresses)

Excluded Middle

a corrupted argument that proposes that since a little of something is good more must be better (or that if less of something is good, none at all is even better). There's no middle ground, it's one or the other extreme

Appeal to Heaven

a dangerous fallacy that asserts that God or a higher power has ordered, supports or approves one's own standpoint or actions so no further justification is required and no serious challenge is possible. "God ordered me to kill my children".

Testimonial

a fallacy in which support for a standpoint or product is provided by a well-known or respected figure who is not an expert and who was probably well paid to make the endorsement

Argument from Consequences

a fallacy of arguing that something cannot be true because if it were the consequences would be unacceptable. "Global climate change cannot be caused by human burning of fossil fuels, because if it were, switching to non-polluting energy sources would bankrupt the American industry".

Appeal to Tradition

a fallacy that a standpoint, situation, or action is right, proper, and correct simply because it has "always" been that way, because people have "always" though that way, or because it continues to serve one particular group well. "Just because we have been doing something doesn't mean we ought to continue"

Shifting the Burden of Proof

a fallacy that challenges opponents to disprove a claim rather than asking the person making the claim to defend his/her own argument.

Law of Unintended Consequences

a fallacy that declares a priori that since we can never know everything or foresee anything, sooner or later in today's "complex world" unforeseeable adverse consequence and negative side-effects will always end up blindsiding and overwhelming, defeating and vitiating any and all "do-gooder" human efforts to improve the world. "There's evil in the world, what's the point of doing good"

Either-Or Reasoning

Essentializing

a fallacy that proposes a person or thing "is what it is and that's all that it is", and at its core will always be the way it is right now.

Also argues that something is a certain way "by nature", an empty claim that no amount of proof can refute

The Paralysis of Analysis

contemporary fallacy of repeating a lie, slogan or deceptive half-truth over and over until people believe it without further proof or evidence
