Loaded Label/Definition

Slippery Slope (Logos)

Based on the fear that once we put a foot on a

slick mountainside, we are doomed to slide right

out of sight

Once we allow medical use of marijuana, we’ll

eventually legalize it for everyone, and then

cocaine and heroin will gain social acceptance.

Red Herring (Pathos)

Throwing an audience off-track by raising an

unrelated or irrelevant point

Debating a gas tax increase is valuable, but I

really think there should be an extra tax on SUVs.

Non Sequitur (Logos)

Means “it does not follow”

Any claim that doesn’t follow from its premises

or is supported by irrelevant premises

I should not receive a C in this course because I

currently have a 3.8 GPA

Post hoc (Logos)

Means “after this, therefore because of this”

Occurs when a sequential relationship is

mistaken for a causal relationship

Cramming for a test really helps because last

week I crammed for my psychology test and I got

an A on it.

A might have been caused by something other

than cramming, must consider all factors

Bandwagon (Pathos)

Appeals to popularity

Popularity of something is irrelevant to its actual

marriage

Living together before marriage is the right thing

to do because most couples are now doing it.

Ad hominem (Ethos)

Means “to the person”

Argument directed at the character of an

opponent rather than at the quality of the

opponent’s reasoning

False Authority (Ethos)

Use famous people to testify on issues about

which these persons have no special competence

Joe Quarterback says Gooey Oil keeps his old

tractor running sharp; therefore, Gooey Oil is a

good oil.

Hasty Generalization (Logos)

Someone makes a broad generalization on the

basis of too little evidence

Evidence needed to support a generalization

must meet the STAR criteria (sufficiency,

typicality, accuracy, and relevance

Appeal to the People (Pathos)

Appeal to the fundamental beliefs, biases, and

prejudices of the audience

Sway opinion through a feeling of solidarity

among those of the group

“Support Our Troops” bumper sticker, often

including American flag, creates an initial feeling

of solidarity among almost all citizens of

goodwill

Car owner may have deeper intention of

meaning “support the war”

Appeal to Ignorance (Pathos)

Persuades audience to accept as true a claim that

hasn’t been proved false or vice versa

UFOs, ghosts, and the abominable snowman do

exist because science hasn’t proved that they

don’t exist.

Appeal to Pity (Pathos)

Arguer appeals to audience’s sympathetic

feelings in order to support a claim that should

be decided on more relevant or objective grounds

Poisoning the Well (Ethos)

Close to ad hominem

Arguers discredit an opponent or an opposing

view in advance

Before I yield the floor to the next speaker, I must

remind you that those who oppose my plan do

not have the best interests of working people in

their hearts.

Straw Man (Ethos)

Occurs by oversimplifying an opponent’s

argument to make it easier to refute or ridicule

Rather than summarize opposing view fairly and

completely, the arguer makes up the argument

they wish the opponent had made because it’s

easier to knock over

Part for the Whole (Logos)

Arguers pick out a part of the whole and then

claim that what is true of the part is true for the

whole

Arguer picks only the best examples to make a

case and conveniently forgets about examples

that weaken the case

http://vimeo.com/17359765

Circular Reasoning (Logos)

Provide a reason that simply restates the claim in

different words

That person is obese because he is too fat.

http://www.youtube.com/watch?v=8CVbku6nxhU

False Dilemma (Logos)

arguer oversimplifies a complex issue so that

only two choices appear possible

One of the choices is made to seem unacceptable

It’s my way or the highway.

http://www.youtube.com/watch?v=Dln3DJEcghY

False Analogy (Logos)

Has to be some similarities between objects being

compared

Has to appeal to audience’s logic
