Fallacies (mistaken beliefs based on an
unsound argument) appear in many forms, as the author
of pearls and elephants recently posted:
Straw man – an argument used against a real person, the key is that
the straw man does not exist but is fabricated to take attention away
from the real person. Discerning a straw man argument means finding out
who the real person is and what he/she stands for – voting records help
with this and are available via Freedom of Information Act requests.
Red Herring – a false plank or issue, similar to the straw man in
that it is a fabrication meant to take attention away from actuality.
Band Wagon – Apple uses this to great effect, it is otherwise known
as the coolness effect. “Everyone is doing it (or wearing it), come
on!” Parents often confront this argument with, “If everyone jumped off
a bridge, or stood on a rooftop to take a selfie, does that make it an
intelligent, informed choice?”
Slippery Slope – an argument that asks you to accept a small step
that leads to another step until ultimately you have strayed far from
the truth. An example comes from a play titled,
A Streetcar Named Desire. In the play, the female lead wears a slip rather than her dress on stage. It caused a furor in 1947 – what about today?
More types of fallacies are discussed here
Fallacies are Red Flags. Other red flags include innocent inaccuracies (errors, mistakes), accidental or intended omissions, author bias, prejudice, deliberate misinformation, phishing. Fallacies are a staple of propaganda.
A great student evaluation activity is to provide examples of fallacious information and have students decide what it is.
What would you say these are:
- Reporter: "It seems to me that if you were elected president, the
Congress with which you would have to work would not be very cooperative
at all. How could you, as president, bring about any reform or help
enact any beneficial legislation with a Congress that was almost totally
opposed to your programs?" Ross Perot: "Well, if I were elected, about
half the members of Congress would drop dead of heart attacks, and half
of my problem would be solved from the outset." [source/answer]
- Environmentalist: "Bicycle infrastructure should be expanded because cycling is a sustainable mode of transportation." Opponent: "We should not build bike lanes because cyclists run red lights and endanger pedestrians." [source/answer]
- Blogger: "I hope the art mural at 34th and Habersham will not be allowed. You
open the gate for one, you open it for all and you'll have it all over
the city. A person wanting to paint on buildings is nothing more than
upscale graffiti. More than likely it will go too far." [source/answer]
- Son: "Wow, Dad, it's really hard to make a living on my salary." Father:
"Consider yourself lucky, son. Why, when I was your age, I only made
$40 a week." [source/answer]
- Voter: "Everyone in Lemmingtown is behind Jim Duffie for Mayor. Shouldn't you be part of the winning team?" [source/answer]
