FEATURED REVIEW
Especially aimed at "group" decision making
Date: December 13, 2011
"Although the initial lectures are helpful with individual and personal decision-making, the majority of
the lectures deal with the even more difficult topic of group decision-making; which makes this course
especially useful and especially aimed at "group" decision-making techniques and processes. So, if you
are involved in business, education, volunteerism, nonprofit, religious, governmental or civic groups,
then you will find this course useful. Prof. Roberto' s lecture style is both energetic and enthusiastic.
Well known in business, defense and academia, Prof. Roberto provides you with a framework for what
both works and fails. Using interesting case studies, he provides real life examples. Many of the
concepts here harmonize nicely with other TTC courses such as Prof. Randy Bartlett's "How to Think like
an Economist". I recommend this course for those tasked with making good critical decisions, especially
within the context of the group."

Terrific course
Date:May 12, 2013
"I am interested in this topic, but not passionately so. The speaker held my attention, explained things I
have observed but never articulated, and offered a prescription for improvement that can be
implemented at the smallest, most mundane level, or at the top, when making decisions of earth
shaking importance. Terrific course!"

Read this book; don't listen
Date:May 8, 2013
"I could get through 75% of this, then fled, shrieking in pain. Prof Roberto is knowledgeable and his
lecture(s) are well written but a horror to hear.
1. His voice is metallic-y grating - he does NOT have to project across a crowded room, have him tone it
down...
2. "Nuclear" is NOT "nuke-ya-ler" (did he go to the GWBush school of public speaking?)
3. "Etc" is NOT "eck-sedera"
4. He inserts the word/question "right?" about 5 times per minute - bad, bad habit
These repeated gaffes make this unbearable listening after awhile. I think he's trainable - how come the
editor/producer doesn't coach him on good public speaking/recording techniques?"

I never thought i would get this much information out of this course. I learn a lot and can use that
thinking to help myself in my own decision making. I would highly recommend the course and anyone
whom doesn't like the course is either in denial or already know the course. Not only does it help in
business but also in life. I found out some good things and things I never knew happen. Such as
President Kennedy backup advisor and that person taught and mentor Kennedy which stunned me . It's
a wonderful course and it really wakes you up."

Analogies, and Analogy Arguments (Problems
printing?Click here.)
If you print this page, you can also download and print thepractice/makeup
exercises. (Make sure the document margins are set to 0.5 inches or narrower.)
Analogies are a vitally important and very powerful communication tool, but from a
purely logicalview, they can be an enormous pain in the fundament. Because
analogies are so powerful they can often convince us of things we have absolutely
no rationalreason to believe. So, before we start, I want to make two things
perfectly clear:
1. Analogies are an enormously useful communications tool. If you can work an
appropriate analogy into whatever you're writing, that will really help you get your
point across. Yea! Go for it!
2. Although there are some good analogy arguments out there, most analogies yousee will be horribly misleading. Horribly, horribly misleading. This is because they
have an insidious power to make us believe things that have absolutely no basis in
fact. (Curse them!)
So, don't be fooled!

Analogy Arguments
Imagine you are a scientist living in the middle of the twentieth century. Imagine that
you have just heard that it has been proved that cigarette smoking causes cancer.
You understand that cigarette smoking involves burning tobacco so that the smoke
may be drawn into the smoker's mouth and lungs. You are aware that cigar and pipe
smoking also involves the inhalation of tobacco smoke. From this, you might
conclude that there is a strong possibility that cigar and pipe smoking also cause
cancer, and that this possibility is strong enough that cigar and pipe smokers should
be warned about it, and responsible parties should conduct specific studies to
investigate this possibility. If you argue that cigar and pipe smoking probably causescancer of the basis of the similarity to cigarette smoking, you will be making what is
called an "analogy" argument because your whole argument will be based on the
similarity between cigarette smoking and cigar and pipe smoking.
Many, perhaps most, speakers and writers use analogies merelyas a communication
tool. An analogy allows a speaker to clarify a new idea by invoking some similarity it
has to some idea with which we are already familiar. Sometimes, however, people
offer analogies in attempts to change minds. In such a case, the analogy is offerednot just to explain, but also to persuade. It is thus then an argumentby analogy.
Empirical arguments by analogy work the way that stereotyping works. We see
something that, in all the ways we can see, is very much like something we've seen
before, so we assume that it's like the thing we've seen before in otherways as well.
Stereotyping exists because it's worked very well as a survival tool. A neanderthal
who'd never seen a sabretooth before might just stand there and be eaten. But if he
notices that the sabretooth looks a lot like a weasel (only much bigger) he mightassume that it will behave like a weasel, which is to say it will attack anything smaller
than it is that looks tasty.
The main reason to use an empirical argument by analogy is that we can'tlook at the
conclusion thingy (the thing the conclusion is about) directly. If we could examine the
-
8/22/2019 Art of Critical Decision Making
10/58
conclusion thingy all by itself to see if it had the property or not, or if we had any
other kind of evidence, we wouldn't bother with an argument by analogy. Thus even
the best argument by analogy is fairly weak, and we usually wouldn't use one unless
we have no other kind of argument availible.
Empirical arguments by analogy generally have conclusions of the form "object O has
feature F " or, less formally, "ferrets are cunning," "pineapples are citrus fruits,"
"dolphins have gills" or "bats can't fly."
These arguments are inductive because their main premises are basically reports, or
summaries of reports, of experiences various people have had. They compare one
thing that is known to exist with another thing that is known to exist in an attempt toshow that the one has some property that the other is known to have. They deal
with physical similarities between objects and situations. They don't deal with
imaginary situations. They don't deal with the issue of whether or not some state of
a world is logically possible, and they are never deductively valid. Thus, at their very
best, they can only give their conclusions a probability of being true, which is what
makes them inductive arguments.
Analogy arguments only work when both sides of the analogy are things that areactually known to exist. Imaginary objects, and objects whose existance is in dispute
won't work here. You can't ever make a successful empirical analogy argument
comparing anything to an object that isn't known to exist. For instance, none of the
following arguments could ever work:
A horse is like a hippogriff. Hippogriffs can fly, so horses can fly.
A unicorn is like a horse. Horses have no magical powers, so unicorns haveno magical powers.
If you take the time to examine any goblin, you will find that it is very, very
similar to you average kobold. And, you have to admit, all kobolds are avid
delvers. Kobolds like nothing better than to delve deep into the living rock
-

under the great hall of the mountain king, so clearly goblins must delve like
the very devil too!
Vampires are like werewolves. Werewolves don't sparkle, so vampires .
. don't. . bloody . . sparkle!Dammit!
The reason is simple. when you're comparing two real things you're comparing
things that are both subject to the laws of nature, like physics, chemistry, biology and
so on. When a physical analogy argument works, (if any of them ever do), it works
because the natural forces forming one object also formed the other one, and if they
formed in similar circumstances, then they're likely to be similar in a lot of ways. (For
instance, sharks are descended from fish, dolphins are descended from land-living
quadrupeds, but the fact that both live by swimming fast means that both need tohave the same streamlined, hydrodynamic shape.) When we're talking about things,
(like basilisks, mermaids, angels, dragons and so on), whose existance hasn't been
documented by science, and which are only really known as hypothetical entities,
anlogies to existing physical objects aren't much use.
Unlike real entities, whose properties are known by primarily through observation,
the properties of hypothetical entities are specified in their definitions. These
definitions may specify an entity that is physically possible, like a unicorn. They mayspecify an entity that is physically unlikely, like a mermaid, or even an entity that is
physically impossible, like thebasilisk, which can kill you with a single glance. Again,
analogies are not much use in such cases.
Standardizing Analogy Arguments
The basic motor of any analogy argument is a comparison, a claim that one thing
is like another thing. (For convenience, and to serve my own bizarre sense of humor,I will refer to these two things as the "premise thingy" and the "conclusion thingy."
The "conclusion thingy" is my name for the thing that is mentioned in
the conclusion of the argument. The "premise thingy" is the thing that
is notmentioned in the conclusion. I call it the "premise thingy" because it
is onlymentioned in the premises.) The way an analogy argument is supposed to
http://en.wikipedia.org/wiki/Basiliskhttp://en.wikipedia.org/wiki/Basiliskhttp://en.wikipedia.org/wiki/Basiliskhttp://en.wikipedia.org/wiki/Basilisk -
8/22/2019 Art of Critical Decision Making
12/58
work is that the two things are supposed to be so much alike that if one of them has
a certain property (call it "the property,") then the other musthave that
same property.
Analogy arguments tend to have the following basic logical form:
1. The Premise Thingy is like The Conclusion Thingy
2. The Premise Thingy has The Property
C. The Conclusion Thingy has The Property
Example 1. The war on drugs is like any war. We will not begin to win until we
begin to shoot drug dealers on sight.
Since this argument is obviously intended to change our minds about the drug war,
the drug war must be the conclusion thingy. The thing it's compared to is a real live
shootin' war, so that's the premise thingy. The property is the thing that is known to
belong to the premise thingy, and which the arguer wants to convince
us also belongs to the conclusion thingy.
Premise Thingy:........Real live warConclusion Thingy....The "war" on drugs
Property ..................Can't be won without shooting at somebody
Why is the drug war the conclusion thingy? Because it's the thingy ... er, thing ... that
the conclusion is about. another way to look at is, if there's two things being
compared, and one of them most definitely has the property in question,
then thatone is the premise thingy. Real wars can only be one by blood, toil, tears ...
I mean shooting. Lots of shooting. With really big guns! Here's how the argumentlooks when it's all put together.
1. The government campaign against illegal drug use is like a literal war with
shooting and bombing and napalm and cool uniforms and so on.
(2. You can't win a real war without shooting at the enemy.)
-
8/22/2019 Art of Critical Decision Making
13/58
C. The government won't win the drug war without a "shoot on sight" order
against drug dealers.
Notice the comparison is clarified in the first premise.
Here are some exercises. Click on the correct premise thingy, conclusion thingy and
property (Or, go to the end of the chapter for the answers.)
1. Dogpatch Community College should not require a freshman writing
course. For god's sake, Harvard doesn't require freshman writing!
Premise Thingy: Dogpatch college....Needs freshman writing....Doesn't need
freshman writing....HarvardConclusion Thingy: Dogpatch college....Needs freshman writing....Doesn't need
freshman writing....Harvard
Property Dogpatch college....Needs freshman writing....Doesn't need
freshman writing....Harvard
2. I cannot believe they teach socialism in the University. It's like teaching
arson in a fireworks factory.
Premise Thingy: Teaching socialism in university....Teaching arson around
fireworks....Good idea....Bad idea
Conclusion Thingy: Teaching socialism in university....Teaching arson around
fireworks....Good idea....Bad idea
Property: Teaching socialism in university....Teaching arson around
fireworks....Good idea....Bad idea
3. Drug use is a matter of behavior control. It's like overeating or gambling. It
would be ridiculous to declare war on overeating, so it's ridiculous to declare
war on drugs.

Vivid vs. Apt Analogies
I'd like to make a distinction here between what I'm calling "vivid" analogies, which
have emotional force because they evoke powerful images and ideas in our minds
without necessarily referenceing any established real similarities, and "apt "
analogies that refer to already established real physical or logical similaritiesbetween two objects. (A good rule would be to ask whether a reasonable would
think that the analogy made sense even if she did not already believe in the
conclusion.) apt analogies can make logically compelling arguments, whether or not
they're vivid. But analogies that are merely vivid, without being aptcan never make
logically compelling arguments.
Just so you know, an argument that uses an analogy that is vivid withoutbeing apt
commits the fallacy offalse analogy.

most important factor. When we are analyzing an argument
we should be prepared to discount the aptness of an analogy whenever that
analogy fails to evoke any powerful image in the reader's mind.
For the following arguments, try to determine whether the analogy used
is vivid or apt or neither or both. (Answers at end of chapter.)
I would suggest that you start each exercise by thinking about how the image makes
you feel. Then give yourself a couple of seconds for the immediate reaction to fade,
and then set that feeling aside and think about whether a reasonable person who
does notaccept the argument's conclusion would accept that the premise thingy and
the conclusion thingy really arephysicallyor logicallysimilar.

Good and Bad Analogy Arguments
What is special about empirical analogy arguments is that they only work if the
similarity between the two objects being compared is extremely strong in areas that
are relevant to the issue being settled. Irrelevant similarities don't count. Irrelevant
differences don't count either. Relevant similarities make the argument stronger.
Relevant differences make the argument weaker. So the thing to do when evaluating
an analogy argument is to pay attention to relevant similarities and differences, and
ignore irrelevant ones.
Unfortunately, analogies are also a powerful instrument of persuasion, even ininstances where they actually carry no weight. Our beliefs about the premise thingy
are often so strong that merely associating it with the conclusion thingy can be
enough to convince us that the analogy is correct even if the two things actually have
nothing to do with each other.
As I've said before, an argument only succeeds if it is clear to you, as a reasonable
person, that it presents a clear and compelling logicalreason for you to change your
mind and agree with the conclusion. If it doesn't seem clear to you that theargument has presented such a reason, then the argument has failed. Since it is
usually possible for two things to be very similar in a lot of ways and yet be different
in precisely the right way to kill an analogy argument, empirical analogies usually
don't present a logically compelling reason to change one's mind, and thus are often
not very logically compelling arguments.
To my mind, analogies nicely encapsulate the basic problem of cutting through
rhetoric. They often have a powerful effect on our imaginations, but they are alsooften complete rubbish. Usually, but not always. Once in a while, an analogy
argument is actually convincing. So your problem, as a critical thinker, is to ignore
the vividness of the image presented by the analogy, and concentrate on whether
the facts presented actually comprise a logically compelling argument for the arguers
conclusion. Just like critical thinking in general, evaluating analogy arguments
-
8/22/2019 Art of Critical Decision Making
18/58
requires you to ignore the powerful effect that images can have on your emotions
and imagination, and to carefully and impersonally trace out the implications of
whatever facts are actually present.
Before you even get into the analogy part of the argument there's a question you
should ask. (Remember that the premise thingy is the thing that is known to have the
property, and the conclusion thingy is the thing that the arguer
wants you to believe has the property.)
1. Does the premise thingy really have the property? If it doesn't, then no amount of
similarity between the two things can make the conclusion thingy have the
property.
If we're sure that the premise thingy really has the property, then we should next
evaluate the strength of the analogy between the two things. The basic way to assess
the strength of an analogy is to think about how the conclusion thingy is similar to
the premise thingy. If the two things are only similar in a way that has nothing to do
with the property, then the analogy is no good. If the two things are similar in a
relevant way, but also have some important differences that are relevant to the
property, then the analogy is no good. If the two things are relatively similar, and
have no relevant differences, you still have to think about whether they are similarenough to make the analogy work. If they aren't, it doesn't. This kind of reasoning is
basically a series of judgment calls, and the only way to get good at it is to practice.
Criticizing An Analogy Argument
The most obvious response to an anlogy argument is to try to break the analogy. You
succeed in doing so if you can show that the two things compared in the analogy are
not similar enough to make the argument work. Here are some examples in whichthe second arguer offers an anlogy breaker. (Such attempts don't always work, of
course, so I'd like you to think a little bit about whether these counter
arguments succeed in breaking their respective analogies.)
1. You can't say that letting George W. Bush be commander in chief during a
-
8/22/2019 Art of Critical Decision Making
19/58
war is like letting a bum off the street coach a Super Bowl team. The U.S.
commander in chief makes general policy decisions based on the advice of
highly trained and experienced professionals. A Super Bowl coach has to
make split-second tactical decisions based entirely on his own judgment.
2. Mountaineering is not like driving. You don't have to climb mountains to get
to the grocery store.
Notice that these are both counter arguments because both of them attack parts
ofotherarguments. Okay, I haven't given you those other arguments, but these two
above onlymake sense as attacks on otherarguments.
The other way to attack an analogy argument is to argue that the premise thingydoesn't actually have the property, as in this dialog.
A. Tobacco smoking is just like marijuana smoking. Both have heath risks,
both can become habitual, and both impose discomfort and risk on the people
around the smoker. We know that marijuana should be illegal, and because of
this similarity, so should tobacco.
B. But we don't have good reason to think that marijuana should be illegal!
The idea that it should be is at least highly controversial, and many health and
law enforcement professionals strongly advocate the legalization of marijuana.
Later on, we will worry about which argument is weaker. For now, I just want you to
notice that the first argument relies upon the claim that marijuana should be illegal.
If this is uncontroversially true, then his argument works. You should also note that
he does not support this claim, so if it turns out to be controversial, then his
argument will fail. The second arguer is trying to take advantage of this by trying to
provide reasons to think that it is not yet proved that marijuana shouldbe illegal.
Now, it should not surprise you to learn that any time an argument has one of these
flaws, it is a bad argument, or a "fallacy."
Fallacies
-
8/22/2019 Art of Critical Decision Making
20/58
False Analogys
The fallacy offalse analogy occurs when an arguer offers an analogy in which the
model and the analog are only similar in ways that are notrelevant to the property,
or in which the model and the analog are clearly different in a way that is very
relevant to the property.
Here are some examples of False Analogy. (With reasons why they're false
analogies.)
Iraq is a lot like Afghanistan, so the war there will go the same way. (Iraq and
Afganistan both have muslim populations, but that's about it. Terrain, populationdistribution, social structure, form of government and military organization are all
different. Since the course of war depends on things like these rather than religion,
the analogy is terrible.)
The national debt is like a metastasizing cancer that threatens to destroy our
economy from within. (The big difference that I see here is that an economy can
recover from just about any kind of "injury," while a living body can be killed by
relatively small injuries. The deficit may indeed be dangerous to our economy, butour economy is not enough like an animal body to make the comparison
meaningful.)
Just as rain wears down mountains, human problems always yield to
perseverance. (Mountains are made of rocks and minerals that have a strictly
limited ability to resist water erosion, while human problems are made of things like
death, anger, hatred, injury, disease and lots of things that don't get better.)
We should have interventions for coffee drinkers, because they're just like
alcoholics. (Yeah, sure, coffee drinkers go on three week binges and wake up in
stolen cars on the edge of the Vegas strip unable to remember their own names and
the names of the oddly dressed farm animals who are currently singing Christmas
carols in the back seat of the car. Yeah, coffee drinkers are juuuuuuuust like

alcoholics.)
Exercises.
For each of the following false analogies, see if you can figure out whyit's a false
analogy.
14. The 40 hour week works very well in modern corporations, so we should
use it in farms as well.
15. Just as it is absurd to criminalize the removal of a tumor, it is absurd to
criminalize abortion.
16. There's no point in adult literacy programs because there's no point in
crying over spilled milk.
17. Coffee and cigarettes should not be illegal, so marijuana should not be
illegal.
Begging the Question
The fallacy of begging the question occurs when an arguer offers any argument, of
any kind, that relies on a major factual claim that is itself controversial and which is
not presently supported by another argument of its own.
Attempts to make analogy arguments can beg the question also. This happens when
an arguer offers an analogy in which thepremise thingyhas not been proved to have
the property that is being ascribed to the conclusion thingy. If the arguer just
assumes that the premise thingy has the property without good reason to think that
it does, then he certainly begs the question, and therefore fails to even get his
analogy argument started.
Just like a business, government must first, last and always look to the bottom
line. (Nobody has proved that businesses have a moral duty to increase profits above
-
8/22/2019 Art of Critical Decision Making
22/58
all else. All established moral theories agree that there are some things that
businesses shouldn'tdo, no matter whatthe profit, so even if government
was exactlylike business, that analogy wouldn't be enough to prove that
government should look to the bottom line.)
Exercise 18. The following argument begs the question. Can you explain
exactly howit does so?
Marijuana should be illegal, so coffee and cigarettes, which are at least as
unhealthy and addictive, should also be illegal.
Red Herring
The fallacy ofred herring occurs when an arguer offers a reason that is not relevant
to his conclusion. In terms of analogy arguments, trying to criticize an analogy
argument on the basis of an irrelevant difference would be a red herring. In the
following examples, the second, red, argument is always a red herring.:
A. Even though God is omniscient, he doesn't know who will repent and who
will not because, for him, it's just like tossing a coin.B. That doesn't make any sense! Deciding whether or not to repent is a
process that takes place in a human brain, which sits in a container filled with
blood, but coin tosses take place in the open air, with no blood anywhere
about!
A. Just as the state has the right to decide who may or may not drive a car, it
has the right to decide who may or may not have a baby.
B. Dude, cars are made of steel and plastic, while babies are made of drool
and squishy pink stuff. There's no comparison, so your analogy fails!
A. Giving a tax break to the rich is like the government seizing a big stash of
stolen money, and then giving some of it back to the bank robbers.
B. But what about the fact that bank robbers wear thos black-and-white
banded jerseys, berets and domino masks? And rich people always wear top

hats, frock coats and Prince Albert beards?
Exercises . Each of the following argument groups contains one red herring (either A
or B). Identify the red herring fallacy and explain why it is a red herring.
19. Promoting a Baha'i society is like promoting Communism. It sounds good
until it's achieved, but then it turns into hell on earth.
A. You forget that Baha'i is a doctrine that came out of the middle east,
whereas communism originated in France and Germany, so your
analogy totallyfails!
B. If the only similarity beetween the two is that they both sound good in
theory, might I point out that both Christianity and indoor plumbing also sound
good in theory.
20. Dogpatch community college should not require a freshman writing
course. For god's sake, Harvard doesn't require a freshman writing course!
A. Can you be sure that these two institutions both draw from the same kind of
incoming freshman pool? Isn't it possible that Harvard's incoming freshmen
are much better prepared than Dogpatch's incomung class?
B. It is abundantly clear that this comparison is logically unsound. It is easy to
prove that what goes for Harvard has absolutely no relevance to what goes forDogpatch, beacuse, ans any educated person knows, the walls of Harvard are
covered in the noble and beautiful ivy, while the walls of Dogpatch Community
College are covered in base and unsightly Kudzu, which is a completely
different kind of plant.
Note for Logic Nerds
If you think about it, false analogy is kind of like red herring because it makes an
argument based on irrelevantsimilarities. However, bad analogies are so common
that it's best to have a seperate fallacy name for that kind of failure.
Here's a rule.
-
8/22/2019 Art of Critical Decision Making
24/58
If it's a direct analogy argument based on irrelevant similarities, it's false analogy s
If it's a non-analogy counter argument based on irrelevant differences, it's one way
of committing red herring.
Fallacy Identification Exercises.
sEach of the red arguments in the following dialogs commits a differentfallacy.
Identify each bad argument as false analogy, begging the question or red herring.
21. A. Drug use is a matter of behavior control. It's like overeating or
gambling. It would be ridiculous to declare war on overeating, so it's ridiculousto declare war on drugs.
Don't be an idiot! Drugs enter the body through the mouth, nose and a needle
into a vein. Except for some very rare circumstances, food only enters the
body through the mouth! Don't you realize what a huge difference that is? It's
an enormous differentce, and it means your analogy cannot possibly work!
22. A. Look dude, your dream of forming a hamster precision flying aerobatic
team is just not going to work. I've told you a thousand times, hamsters don't
fly, and that's it!
Don't be a fool, old man. Don't you know that hamsters are almost exactly like
lemmings, and it is well known that the lemming can fly with the agility, grace
and power of a F15 Tomcat jet fighter. Since lemmings can fly, it follows that
tight formations of hamsters can fly well enough to give aerobatic displays of
stunning complexity and precision.
23. A. Is that a Sherman tankyou're driving? I thought you were trying to save
money. That thing must get terrible gas mileage.Oh no, it will get great gas mileage, because I got a blue one. My old Pacer
got great gas mileage, and it was blue too.
Tactics and Analogy Arguments
-
8/22/2019 Art of Critical Decision Making
25/58
Okay, let's say you've got to analyze a set of arguments in which at least one of them
is an analogy argument. How do the opposing arguments stand to that analogy
argument. The rule is simple. If the opposing argument tries to break the analogy,
then it's a counter argument. If it doesn't offer any specific reasons to doubt the
analogy, then it's a direct argument.
Salience
"Salience" is the property of "stick-outness" something is salient if it it really grabs
out attention. Explosions, people who look like movie stars and giant, world-
destroying spaceships are really salient. Cars that happen not to be exploding,
people who look like everybody else, and small, innoffensive pieces of gravelare notsalient. Now, there is a great deal of difference between salience and logical
force. This is very like the difference between vividness and congruence. Salient
features can catch our imaginations and move us to belief without providing even
the beginnings of a logical reason to believe. And salience can, sometimes fatally,
distract us from the purely logical features of an issue. Consider the following dialog:
A. Dolphins and sharks have many similarities. They are both shaped very
much the same, and are optimized for fast swimming. They are also both builtfor manuverability in that they both have strong dorsal, ventral and caudal
fins. Finally, they both live the same way, by chasing down and eating smaller
fish. So the fact that sharks have gills leads inevitably to the conclusion that
dolphins must also have gills..
B. Dude, dolphins are mammals, not fish! Mammals have lungs, not gills!
Before you begin a serious analysis, take a moment to think through your own
reactions to these arguments. Did you laugh? Did something strike you as especially
stupid? Did anything strike you as right on the money? Take a careful inventory of
your initial reactions and ideas about this dialog, and write down as much as you can
of what you thought.
Then look at the second argument, and ask yourself if it is a counterargument. It's
-
8/22/2019 Art of Critical Decision Making
26/58
true that the first argument is ludicrous, but that's not the issue here. The question
here is whether or not the second argument refersexplicitlyto the facts and logic
that thefirstargument uses. The second argument is onlya counter argument if it
actually gets into the nuts and bolts of the first.
Finally, look at the second argument, and ask yourself if it represents good logic.
I'm not asking you if it's true, I'm asking if it's good logic. The way to think about this
kind of issue is to ask youself if a person who did not already believe the
conclusion would rationally have her mind changedby the argument. Here, the issue
is whether dolphins have lungs or gills, so I want you to think about whether
someone who didnotalready think dolphins have lungs would get a rational reason
to change his mind, and believe that dolphins did have lungs, or to at least believe
that the first argument was no good, based on this second argument.
If I've handled this example correctly, you will have been at least mildly surprised by
your own responses to these two questions. Because the conclusion of the first
argument is so absurd, I expect many people will instinctively tend to feel that
the secondargument mustbe either a counter argument or good logic, or both. In
fact neither is the case. The second argument is nota counter argument, because it
does not refer in any way to the analogy between dolphins and sharks. Furthermore,
it is bad logic, committing the fallacy of begging the question. The statements"dolphins are mammals" and "dolphins have lungs, not gills" are pretty much
synonymous in this context. If someone believes that dolphins are mammals, he will
automatically believe they have believe that they have lungs. If someone doesn't
believe that dolphins have lungs, he automatically won't believe that they're
mammals, and so the premise "dolphins are mammals" will notbe uncontroversial as
far as he is conceerned.
Here are some more examples offalse analogy, withopposing direct and counter arguments. The counter arguments give
reasons whythese are false analogies. The opposing direct arguments ignore the
analogies.
Iraq is a lot like Afghanistan, so the war there will be a cakewalk, just like
-
8/22/2019 Art of Critical Decision Making
27/58
Afghanistan.
Direct: The Iraqi resistance is highly motivated and well-funded. They're not
going to allow a cakewalk!
Counter: Iraq and Afganistan both have muslim populations, but that's about it.
Terrain, population distribution, social structure, form of government andmilitary organization are all different. Since the course of war depends on
things like these rather than religion, the analogy is terrible.
We should have interventions for coffee drinkers, because they're just like
alcoholics.
Direct:Are you crazy? Coffee drinkers need that black elixir, that steaming
java, that jittering caffeine high!
Counter: Yeah, sure, coffee drinkers go on three week binges and wake up instolen cars on the edge of the Vegas strip unable to remember their own
names and the names of the oddly dressed farm animals who are currently
singing Christmas carols in the back seat of the car. Yeah, coffee drinkers are
juuuuuuuust like alcoholics.
Just as it is absurd to criminalize the removal of a tumor, it is absurd to
criminalize abortion.
Direct:Abortion allows women to control their own bodies! We can't have that.
Counter: Tumors don't ever turn into people. Well, except for Glenn Beck.
There's no point in adult literacy programs because there's no point in crying
over spilled milk.
Direct:Adult illiteracy is a tragedy for millions of people who would like to read
the articles in playboy, but can't.
Counter: Milk can't be unspilled, but illiterate adults can learn to read.
The national debt is like a metastasizing cancer that threatens to destroy oureconomy from within.
Direct: Rubbish, debt is good for an economy. Debt is what makes this country
great!
Counter:An economy can recover from just about any kind of "injury," while a
living body can be killed by relatively smallinjuries. The deficit may indeed be
-
8/22/2019 Art of Critical Decision Making
28/58
dangerous to our economy, but our economy is not enough like an animal
body to make the comparison meaningful.
If I've done this right, you'll be able to look at the examples above and see that
the counterarguments all point out differences between the two objects beingcompared in the analogy argument, while the direct arguments all ignore the
analogies.
Exercises For each of the following groups of arguments, identify the argument that
is a counter argument to the first argument,
24. I'm tired of those crazy drivers on the 405, so I got myself an old armytank! And I know it will get great gas mileage, because I got a blue one. My
old Pacer got great gas mileage, and it was blue too.
A: Pshaw! As if color has anything to do with gas mileage!
B: Um, tanks are lots heavier than cars, so your tank will get lousy mileage!
25. The 40 hour week works very well in modern corporations, so we should
use it in farms as well.
AThe 40 hour week means weekends off, and crops and animals don't dowell when left alone.
B: Corporations usually deal with non-living things, like papers and widgets.
Farms deal in living things, like plants and animals.
26. Just as rain wears down mountains, human problems always yield to
perseverance.
A: Mountains are made of rocks and minerals that have a strictly limited ability
to resist water erosion, while human problems are made of things like death,
anger, hatred, injury and disease.
B:Actually no, lots of human problems totally fail to get better, no matter how
long and hard people try.
27. Coffee and cigarettes should not be illegal, so marijuana should not be
illegal.
-
8/22/2019 Art of Critical Decision Making
29/58
AMarijuana makes people happy at low cost. Our corporate overlords cannot
profit from that, so it should be illegal.
B: Coffee and cigarettes are way more addictive than marijuana. Neither of
them is a serious intoxicant compared to marijuana, so the analogy doesn't
work..
28. Given what we know about logic, can you figure out a good counter argument to
the "dolphins have gills" argument above?
29. Given what we know about science, can you figure out a good direct argument
for the conclusion that dolphins don'thave gills?
SCAEFOD
"SCAEFOD" stands for "Standardize, Context, Analyze, Evaluate, Fist Of Death!" It
refers to a process in which an effort is made to clarify arguments and the logical
relationships between arguments before any decisions are made about the strength
or weakness of any argument.
Here's example of how to "scaefod" (analyze) an analogy argument.
William Bennett holds up an egg. "This is your brain," he says. He cracks the
egg, dropping the contents into a hot skillet. The egg cooks. "This is your brain
on drugs." Bennett turns to the Emmett, looking very grim. "Any questions?"
He asks.
Emmett.Yes Bill, can I have my brain on drugs with bacon and toast?
William Bennett 1. An egg that is cracked open and dropped into a hot skillet
will become coagulated and tasty.
(2. It is an extremely bad thing, from the egg's point of view, to
become coagulated and tasty.)
(3. The human brain exposed to drugs is like an egg cracked
and dropped in a hot skillet.)
C. All drugs are extremely
-
8/22/2019 Art of Critical Decision Making
30/58
bad. DIRECT
Emmett. No argument, just a sarcastic comment.
William Bennett bears the burden of proof here. Although many people believedrugs are bad, and some recreational drugs have been shown to have some bad
effects under some circumstances, all the evidence so far shows that drugs are not
seriously damaging for the majority of people who take them.
William Bennett Analogy Argument Emmett. No argument
Analog: brain on drugs
Model: egg on skillet
Property: becomes coagulated and tasty, (and is perhaps served withbacon and toast, and maybe coffee.)
William Bennett: Analogy between brain on drugs and egg on skillet
Most relevant similarities. None.
Most relevant differences. There is no known drug experience that is remotely like
hitting oneself in the head with a hard heavy object and then laying one's exposed
brain in a hot skillet.
Fist of Death: Based on the conversation between William and Emmett, drugs are
not seriously dangerous. Emmett gives no argument, but since he defends the null
hypothesis, he doesn't really have to. William gives the analogy between taking
drugs and banging oneself in the head, cracking one's head open and dumping one's
brains into a skillet. There is no known drug that has this effect, so William's analogy
is completely false. Given that we have no anti-drug arguments left here, the
proposition that drugs are not seriously damaging carries the day.
(Again, one's pre-existing beliefs about the level of danger attendant on taking illegal
drugs cannot be relevant here.)
One last example before the exercises.

31/58
Shakira. Marijuana has been proved to cause at least some brain damage, so
I think marijuana should be illegal, at least until we can establish exactly how
dangerous it is.
Jameson. Rubbish, Red Bull and other "energy drinks" are not illegal, so
marijuana should not be illegal.
Shakira. 1. Marijuana causes some brain damage.
2. We're not sure exactly how
much.
C. Marijuana should be illegal, at least for the present.
DIRECT
Jameson. 1. Red Bull and other "energy drinks" are not illegal.
2. Marijuana is similar in its properties to these energy drinks.
C. Marijuana should not be illegal. DIRECT
Shakira makes a direct argument.
Jameson doesn't talk about the logic of Shakira's argument, so his is also a direct
argument.
Shakira is the one arguing that something could be illegal, so she bears the burden of
proof.
Shakira. Explanation argument Jameson. Analogy
argument.
Based on harm caused by marijuana. Analog: marijuana.
Model: "energy drinks"
Property: should be legal
Jameson. Analogy between marijuana and energy drinks.Most relevant similarities: Both marijuana and "energy drinks" contain naturally
occurring psychoactive chemicals.
Most relevant differences: None that I can think of.
Fist of Death: By the reasoning given above, marijuana should be illegal. I don't think
-
8/22/2019 Art of Critical Decision Making
32/58
that Shakira's argument is particularly strong, but it doesn't commit any obvious
fallacies. The analogy between marijuana and Red Bull-type drinks seems very
strong, so ifit is the case that these drinks shouldbe legal, it follows that marijuana
also should be legal. However, the fact that something is legal doesn't mean it should
be legal, so even if marijuana was exactly like these currently legal "energy drinks,"
that analogy wouldn't be enough to prove that marijuana should be legal. Jameson
commits the fallacy of begging the question, because his model, energy drinks,
doesn't have the property he thinks it does. So Shakira's argument is the strongest
out of these two, and if these arguments were all we had to go on, we would be led
to conclude that marijuana should be illegal.
Exercises 30-31. Analyze the following
Arguments
Carli. Drug use is a matter of addiction and behavior control. It's like
overeating or gambling. It would be ridiculous to declare war on overeating, so
it's ridiculous to declare war on drugs.
Syed. The war on drugs is like any war. We will not begin to win until we
begin to shoot drug dealers on sight.
ThesisBased on the discussion between Carli and Syed, it is ridiculous to declare war on
drugs.
Support
As Carli says, drug use is like overeating or gambling. (At least, problem drug use is
like problem overeating or problem gambling.) These three things are especially
similar in terms of addiction, which we can define as the fact that they all involve
cravings and involuntary impulses to indulge in the problem behavior. Thus it makessense that they should be handled in terms of helping individuals gain greater
control over their behavior. It would be ridiculous, or at least very counterproductive
to try to combat overeating by declaring war on food, and so it is ridiculous to try to
combat problem drug use by declaring war on drugs.

Exercise 30. Pick out the best description of Syed's stupid argument.
A. "Syed draws an analogy between the war on drugs and regular wars such as the
War of 1812 and World War II. Such wars can only be won by undertaking offensive
actions against the enemy, which includes shooting at the enemy on sight. Syed
implicitly argues that, since fighting a regular war requires shooting the enemy on
sight, fighting the war on drugs requires shooting drug dealers on sight." (Answer)
B. "Syed draws an analogy between the metaphorical "war" on drugs, and the literal
meaning of the word "war." He claims that the "war" on drugs is exactly the same as
wars such as the War of 1812 and World War II. Syed implicitly assumes that "wars"
in the literal sense can only be won by undertaking offensive actions against theenemy, which obviously includes shooting at them whenever such shooting is to our
advantage. He also implicitly identifies drug dealers as the "enemy" in the "war" on
drugs. Since he says "shoot drug dealers on sight," he is literally advocating that
police or anyone else should open fire as soon as they catch sight of anyone they
believe to be a drug dealer." (Answer)
C. "Syed draws an analogy between the metaphorical "war" on drugs, and the literal
meaning of the word "war." He claims that the "war" on drugs is exactly the same aswars such as the War of 1812 and World War II, at least in terms of how they can be

undertaking offensive actions against the enemy, which obviously includes shooting
at them whenever such shooting is to our advantage. He also implicitly identifies
drug dealers as the "enemy" in the "war" on drugs. He is saying that the police
should undertake offensive operations against drug dealers in the same way as a
well-run army undertakes operations against an opposing army. This would
presumably include intelligence efforts to correctly identify and locate genuine drugdealers, and careful consideration of when and how to open fire in order to minimize
the probability that innocent people would be caught in the crossfire." (Answer)

undertaking offensive actions against the enemy, which obviously includes shooting
at them whenever such shooting is to our advantage. He also implicitly identifies

dealers on sight," we don't need to read him as literally advocating that police or
anyone else should open fire as soon as they catch sight of anyone they believe to be
a drug dealer. Rather we can interpret him as saying that the police should
undertake offensive operations against drug dealers in the same way as a well-run
army undertakes operations against an opposing army. This would presumably
include intelligence efforts to correctly identify and locate genuine drug dealers, and
careful consideration of when and how to open fire in order to minimize the
probability that innocent people would be caught in the crossfire." (Answer)
Possible Clinchers
Exercise 31. Pick out the best critique of Syed's stupid argument.
A. "Syed's argument does not address the analogy offered by Carli. Since Syed fails to
offer a counter argument to Carli's argument, Syed cannot defeat that argument,
and it stands. Since Carli's argument stands uncontested, it carries the day, and Syed
loses the argument." (Answer)
B. "Syed's argument commits two fallacies. First, he commits the fallacy of assuming
that, if the war on drugs really is like a real war, it automatically follows that shooting
the "enemy" would be justified. This is an illegitimate assumption because it is simply
not the case that all wars are justified. Second, he commits the fallacy of false
analogy in that the war on drugs and real warfare are not sufficiently similar to carry
his argument. Enemy soldiers are dedicated to shooting us and blowing up our stuff.
Drug dealers are dedicated to selling their stuff to people who want to buy it. Theyonly shoot or blow up people who threaten them. Otherwise, they leave us alone.
The only justification for shooting at enemy soldiers is that it can prevent them from
shooting at us. When shooting them isn't needed to stop them shooting at us, like
when they surrender, we stop shooting at them, eventually. Since this difference sits
right on the point that Syed needs in order to make his argument work, it kills his

argument stone dead." (Answer)
C. "The problem with Syed's argument is that it requires literal warfare against drug
dealers. This means attacking them with the most effective weapons in our arsenals.
Can you imagine the carnage if your local corner drug dealer suddenly found himself
attacked by an armored division operating with air support. Sure, a single hit from
the main gun of a modern main battle tank would vaporize the guy, but it would also
bring down every nearby building. Cluster bombs and napalm would only make
things worse. Undertaking modern warfare in an urban environment would cause
untold destruction, so is ridiculous to apply modern warfare to drugs." (Answer)
D. "Syed's argument is a false analogy. There is no way that the war on drugs is
anything like a regular war, so things that apply to a regular war do not necessarilyapply to the war on drugs." (Answer)
An argument cannot be a bad argument merelybecause it fails to address some
other argument. An arguer can fail because he fails to address some other argument,
but that by itself doesn't make his own arguments bad. Taking an uncharitable
interpretation of somebody's argument, and then refuting, or ridiculing, that
uncharitable interpretation, always fails to refute an argument. In order to really
defeat an argument you have to criticize it in its strongest form, and show that evenits strongest form cannot stand. Finally, even if your judgment of an argument is
exactly right, your clincher will still fail if you do not include the details necessary to
allow your readers to understand exactly why the opposition argument fails.
