Transcript Red Herring

Red Herrings
Example 1
(from The Fallacy Detective)
Jenny: “Girls are much smarter than boys.”
Bert: “Oh yeah. How do you know that?”
Jenny: “Because, they just are.”
Bert: “But how do you know it?”
Jenny: “There are lots of girls who have done
lots of smart things. Our neighbor, Mrs. Jones,
is pretty smart; Joan of Arc saved the French
from the English; and Madame Curie invented

the light bulb.”
Bert: “But how do you know they are smarter
than boys?”
Jenny: “Because there are many girls who have
high IQs. That makes them smart.”
Bert: “You still haven’t answered the question.
Why are girls smarter than boys?’
Jenny: “Well, I’m smart and you’re dumb. That
proves it.”
Red Herring
When someone is avoiding the question and
asserting something irrelevant, we say they
are introducing a red herring into the
argument.
A red herring is a dead fish – started to become
“ripe” and smelly
Where does the term come from?
Definition
A Red Herring is the introduction of an irrelevant
point into an argument. Someone may think
(or they may want us to think) it proves his
side, but it really doesn’t.
Example 2
Jenny: “I think boys should always open doors for girls.”
Bert: “Why?”
Jenny: “Because, that is the gentlemanly thing to do.”
Bert: “Why is that the gentlemanly thing to do?”
Jenny: “Because it is very helpful for the girls.”
Bert: “But wouldn’t it also be a helpful thing for the boys
if all the girls opened the doors for them? Why don’t all
the girls open the doors for the boys?”
Jenny: “Because that isn’t right. This afternoon, when we

were coming out of the grocery store, I had several
bags in my hands and I had to put them all down
to open the door, just because you were too rude
to help me.”
Bert: “I couldn’t help you open the door because I
was out in the parking lot waiting in the car.”
Jenny; “See what I mean? You were too
inconsiderate to think that I might need some
help when I came out of the grocery store. I think
that was ungentlemanly.”
Example 2 Continued
Bert: “I didn’t know that you were going to buy
so many groceries, otherwise I would have.”
Jenny: “You should have thought of that.”
Not a Red Herring
When someone says, “I don’t know,” and
doesn’t answer the question, he is not
introducing a red herring. He is still addressing
the topic – he just doesn’t have an answer.
Exercise #1
(from The Fallacy Detective)
In the following examples, is the speaker addressing the
question and staying on topic?
1. Son: “Why can’t I go see the movie The Day of the
Spatulas” with my friends?”
Dad: “Because it’s a scary movie and you shouldn’t
see scary movies when you are this young.”
He is answering the question.
2. Son: “Why can’t I go see The Day of the
Spatulas with my friends?”
Dad: “Because January 1 falls on a Wednesday
this year.”

3. Son: “Why can’t I go see The Day of the
Spatulas with my friends?”
Friend: “Because you don’t have enough
money for the ticket.”
He is answering the question.
4. Son: “Why can’t I go see The Day of the
Spatulas with my friends?”
Dad: “Isn’t there some other kind of movie
you could go to see instead?”
RED HERRING!
5. Son: “Dad, can I go see The Day of the
Spatulas with my friends?”
Dad: “Why don’t you go ask your mother?”
RED HERRING!
6. Son: “Dad, can I go see The Day of the
Spatulas with my friends?”
Dad: “No.”
He is answering the question.
7. Son: “Dad, can I go see The Day of the
Spatulas with my friends?”
Dad: “I don’t know. What is The Day of the
Spatulas? Is it about pancakes?
He is answering the question.
8. Son: “Dad, why did you go to see the The Day
of the Spatulas, when you said I couldn’t?”
Dad: “It was a really good movie. I’ll take you
to see it next week.”

Recognizing Red Herrings
“Sparkledent is great for reducing cavities.
Dentists say cavities are the number one
dental problem in America.”
“Sparkledent is recommended by dentists
everywhere as the number one cavityreducing toothpaste, so you should use it.”
Red herrings are often good arguments. The
only problem is, they don’t prove the point
being argued – they prove something else.
