    Cause/Effect

    Most Important of Logical Relationships

    We want to know not only what happens but why

    it happens.

    We want to know why national debt cant be

    brought under control.

    We want to know why we have unemployment.

    We want to know why our cities decay from theinside out.

    We want to know the effects of using pesticides.

    3/70

    Cause/Effect

    . We want to know the cause of our young people takingLSD and Crack..

    We want to know the short and long range effects of theiracquired habit.

    We want to know why gang violence is on the increasein the affluent suburbs.

    GM, Ford, and Chrysler want to know why the Japaneseand German car manufacturers are beating the pants off

    from them. Divorced people want to know why their marriages fell

    apart.

    4/70

    Cause/Effect

    Causal reasoning may move in either

    direction from the cause to the effect or the

    effect to the cause.

    As a matter of fact, the effect may become

    another cause.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    5/70

    Cause /Effect Work piles up. I feel under stress because of the work piling up.

    I sip three glasses of Vodka to relieve stress.

    I become mellow and allow work to pile up.

    I feel anxiety because while I became inebriatedmore work piled up.

    I down myself for letting work pile up.

    I feel guilty in so doing. The guilt leads to stress.

    I sip three glasses of Vodka to relive stress..

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    6/70

    Cause/Effect

    Dr. Albert Ellis in his bookOvercomingProcrastination illustrates how an effect can becomea further cause:

    Consider Debbies problem of doing the dishes:

    Activating Event- observing dirty dishes in thesink.

    Beliefs- How annoying to clean them, but Idbetter. (rational).

    I cant stand this mess. It looks too tough to tackle.(irrational)

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    7/70

    Cause/Effect

    Consequence- frustration.(rational)

    Reaction- do the dishes.(rational)

    or--avoid doing the dishes. (irrational)(Ellis, Overcoming Procrastination, p29-

    30)

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    8/70

    Cause/Effect

    Thirteen-year-old Paul keeps thinking he would like to

    clean up part of the cellar at his parents house in order to

    make a game room.

    He has contemplated this for the past three years and,rather than getting started, he tries not to think about the

    long-delayed project because when he reminds himself to

    do some work he lambasts himself for the time he

    already has wasted. (Ellis, Overcoming Procrastination,

    P.9)

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    9/70

    Cause/Effect

    . The next portion of this lesson we will

    stress terminology, stages in causal

    reasoning, and a list of problems that

    frequently occur in causal analysis.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    10/70

    Cause/ Effect

    We can classify causes as Necessary,Sufficient, orContributory .

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    11/70

    Cause/Effect

    Necessary

    Sufficient

    Contributory

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    12/70

    Cause/Effect

    Necessary Causes

    The necessary cause must be present in order for the effect tooccur.

    For example, the Flu virus must be present in order for the effect

    (the disease) to occur. A person may make himself more susceptible by staying up until

    4:00 AM.

    A person may make himself more susceptible by a haphazarddiet of junk food.

    A person may make himself more susceptible by walkingaround in the rain with no shoes.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    13/70

    Cause/Effect

    A person may make himself more susceptibleby sitting in a draft.

    But we can consider none of these items as thenecessary cause of the Flu. The Flu Bug has to

    attack before the willfully derelict individual getsthe Flu.

    Example: Necessary Cause: A spark is necessary toignite a gasoline engine.

    The HIV virus must be present for AIDS to occur.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    14/70

    Cause/Effect

    A Sufficient Cause has the capability of

    producing an effect unaided. More than one

    sufficient cause may produce the same effect.Example: A cough can be produced by a cold

    virus, pneumonia, emphysema, lung cancer,

    tuberculosis, an abscess on the larynx, smog,

    tobacco juice, Tabasco sauce,or chalk dust.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    15/70

    Cause/Effect

    : A dead battery can prevent a car from

    starting, but so can a faulty spark-plug,

    water in the distributor, or no gasoline.

    22/70

    Cause/Effect

    Contributory Causes

    A contributory cause can help to produce an effect, butcannot do so by itself.

    Example: Running through a red light may cause an

    accident. Example: Skipping class may cause a failing grade when

    linked with other causes.

    Example: Smoking may contribute to lung cancer, but it is

    not necessarily the major cause or the sole cause.( Thebody can withstand remarkable abuse).

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    23/70

    Cause/Effect

    Stages in Causal Reasoning

    James Mc Crimmon has identified three stages in causalreasoning:

    1. Whatever the cause, it must exist in the situation

    and must be sufficient to produce the effect. This step requires the investigator to identify all of the

    possible causes, isolating which of the possible causescould be sufficient to produce the effect.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    24/70

    Cause/Effect

    Example: The cold water in the Dorm shower

    could be caused from:

    a defective fuse

    power company failure

    burned out element

    excessive use of shower by room mate

    Any one of these (with the possible exception ofthe last one) could bring about the effect unaided.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    25/70

    Cause/Effect

    2. If a sufficient cause is eliminated from thesituation, the effect will be eliminated unless thereare other causes. If the effect ceases when we remove

    the possible cause, the possible cause is the cause. Example: If we suspect that a faulty bulb is the cause

    for no light, we simply make a substitution-with a newbulb. If it is the cause we look no further , not ruling out

    the possibility that the original bulb may only be acontributory cause.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    26/70

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    27/70

    Cause/Effect

    3. If the cause is introduced into a similar situation,it should bring about a similar effect.

    Example: If we suspect a faulty battery, fuse, or bulb, we

    could insert one into a different socket or receptaclewhere one has been operating. If the battery or fusedoesnt work, or the light doesnt turn on, we reject ourhypothesis. But if the fuse or battery work or thelightbulb turns on, we have additional support for our

    belief in the original hypothesis.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    28/70

    Cause/Effect

    Errors in Causal Reasoning

    Louise Rohrabacher has identified ten

    separate errors in causal reasoning:

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    29/70

    Cause/Effect

    1. Mistaking a time connection for a

    causal one.

    This error has sometimes been referred to as

    thePost Hoc Ergo Propter Hoc

    fallacy, translated into English as After

    this , therefore because of this.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    30/70

    Cause/Effect

    Superstitions are based upon this fallacy:

    After I touched the toad, I got warts.

    An owl hooted before Uncle Marvins death. An

    owl hooting will somehow bring about death. Labor Day, because it always occurs before the

    opening of school must somehow cause the opening of

    school.

    The 9:00 class occurs before the 10:00 class. The9:00 class must cause the 10:00 class.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    31/70

    Cause/Effect

    I dont want to hold hands with any girl.

    When Travis held Cindys hand, he

    flunked his spelling test.

    After Hoover was elected, we had a

    Depression. Hoover caused the Depression.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    32/70

    Cause/Effect

    2. Mistaking for a cause things that

    coincidentally happen at the same time- also

    known as the concurrent fallacy.

    If two things are concurrent ( take place at thesame time), It does not mean that they are related.

    Example: If the Southern Baptist Convention and

    the National Gay Coalition hold their meetings inthe same city or perhaps the same hotel, we cannot

    assume that the two events must be related.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    33/70

    Cause/Effect

    Example: Colored leaves in the fall arebelieved to be caused by the frost.

    Some things are genuinely coincidentalsuch as the incident in which a young ladyaccused a man of following her when

    actually they were going in the samedirection at the same time for a totallyunrelated reason.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    34/70

    Cause/Effect

    3. Beware of thesingle cause fallacy.We cannot settle for one single cause if

    there are more. Most effects stem from multiple causes

    rather than just one. Remember, the last

    straw did not break the camels back byitself. The single cause fallacy results fromjumping to conclusions.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    35/70

    Cause/Effect

    Example: A motorist hears someone honking at

    him. He jumps to the conclusion that they want

    him to go faster. Other reasons the other motorist

    may be honking could include: His transmission may be coming loose

    He may be honking because he recognizes him

    He may have a bumper sticker which reads,Honk if you love Jesus.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    36/70

    Cause/Effect

    Many newspaper headlines reveal the

    single cause fallacy:

    Sex education causes promiscuity.

    Television destroys a students capacity

    to read.

    Comic books cause juvenile

    delinquency.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    37/70

    Cause/Effect

    James Mc Crimmon suggests that attributing racial

    strife to differences in skin color ignores the other

    social and economic causes.

    Randal Decker suggests that the writer whobrings his old prejudices to the task of causal

    analysis or fails to see the probability of multiple

    causes or effects is certain to destroy his analysis,

    making it so superficial it becomes worthless.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    38/70

    Cause/Effect

    Be sure to distinguish between immediate

    and remote causes.

    Example: Instructor Why are you here at Texas

    College? Student: Because my father married my mother.

    This line of reasoning starts back too far. We needto look at the immediate rather than the remote

    causes.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    39/70

    Cause/Effect

    Example: Why did Jeffrey Dhamer slay thoseyoung boys and have homosexual relations withthem?

    Well, it all started with Cain and Abel. or It allstarted when Lucifer decided to rebel againstGod.

    Why is Elizabeth Taylors marriage on the rocks?

    It all started in the Garden of Eden when Evedecided to eat the forbidden fruit.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    42/70

    Cause/Effect

    Ever pervasive desire to make profit

    Higher production costs

    Labor costs

    Weather factors

    Economic well-being of nation.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    43/70

    Cause/Effect

    In 1991, Iraqi Foreign Minister Teriq Azizinsisted that Iraq invaded Kuwait because Israeloccupied the West Bank.

    Such tangential remote excuses for suchbizarre behavior doesnt even qualify as arationalization.

    represents a tortured extremely remote cause.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    44/70

    Cause/Effect

    5. Be sure the cause has the capacity to produce the effect.

    Louise Rohrabacher describes an incident in which aperson leaves a big juicy beef steak on the table. When hereturned, the steak was gone. If a huge Great Dane or Black

    Labrador were left in the house, and perhaps furthercircumstantial evidence appeared such as red bloody juicedripping from the muzzle, distended ribs on the dog, asheepish look on the dogs face, etc., we have a primesuspect. A lone kitten asleep in the corner would be

    exonerated.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    45/70

    Cause/Effect

    Back in 1349, the Black Death wiped

    out 2/3 of Europes population. The Jews

    were blamed for poisoning the wells. There

    were not that many Jews in all of Europe toaccomplish such a task.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    46/70

    Cause/Effect

    A story circulated about a man who wentdown in a mine with a hammer and saw.The mine later collapsed and the man was

    blamed. It was later determined that thewidth of the beams and the sturdiness of thestructure made it impossible for the man toinflict that much damage and eventually

    another explanation was sought.

    47/70

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    48/70

    Cause/Effect

    Proponents of Womens Suffrage felt that the votewould cure societys ills and bring equality for all.

    Proponents of the ERA amendment naivelyassume the same thing. The ERA will probably beas effective at promoting equality as the balanced

    budget amendment will bring our deficit undercontrol.

    The O.E.O. did not do away with poverty.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    49/70

    Cause/Effect

    The crime bill, replete with midnight basketballand handicrafts will not do away with gangviolence.

    Economic ills cannot be treated until thecomplexity of the issue is addressed and the greedfactor of human nature is checked.

    The argument that productivity itself will improve

    the economy fails to take into account thatproductivity by itself will not bring down pricesunless companies are willing to turn out more forless profit.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    50/70

    Cause/Effect

    7. Allow for causes that may nullify predicted

    effects.

    Example: The increase in the minimum wage is a

    short sighted view some labor leaders see as asolution. But wage increases lead to higher prices to

    pay for the wage increases-leading to another

    unfortunate effect -a higher cost of living- refueling

    a demand for another wage increase.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    51/70

    Cause/Effect

    Example: When the federal government

    closed down Fort Ord and the San Diego

    Shipyard, it did so as an economy move,

    not realizing that depressing the localeconomy created a greater demand for

    disaster relief, wiping out all the economic

    gains.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    52/70

    Cause/Effect

    Example: People feel more empowered

    if they are given more credit,

    but the more credit one has, the more the

    bank reckons the liabilities potential.

    If you can borrow $50,000 on your

    signature, you can also owe the bank

    $50,000 on your signature.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    53/70

    Cause/Effect

    Example: Governmental subsidies can prop

    up prices artificially, but can weaken

    companys resolve to compete in the world

    market.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    54/70

    Cause/Effect

    8. Avoid predicting contradictory effects.

    Example: Sometimes it is impossible for two

    predicted effects to exist side by side. Louise Rohrabacher once used the example of a

    politician who promised to lower taxes, increase

    public works, increase military spending and

    social programs, and balance. the budget.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    55/70

    Cause/Effect

    Example: Hillary Clintons recent health

    care package which would have

    commandeered 1/7 of the national

    economy would cost the average tax payermore, and would not constitute free health

    care at all.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    56/70

    Cause/Effect

    9. Do not mistake the cause for the effect

    or the effect for the cause.

    Example: Louise Rohrabacher suggests

    that Medieval philosophers tried to

    substantiate the goodness of God because

    He made a great river run through every

    city.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    57/70

    Cause/Effect

    Example: We hear about the old farmer

    who says, If Id Known I was going to

    have such nice children I would have

    picked a better mother for em. (notrealizing that the mother was a contributory

    cause of his nice children.)

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    58/70

    Cause/Effect

    Example: We hear the caution, Dont eat

    too much sugar. You will get diabetes.

    Actually , sugar consumption is a symptom,

    not a cause of diabetes.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    59/70

    Cause/Effect

    Example: When people think that a high

    fever causes the Flu, they will think that

    putting ice packs on their forehead will

    actually cure the Flu.

  • 8/14/2019 COMFTF07Causal Analysis Rev 03-12-06.

    60/70

    Cause/Effect

    Example: When a motorist blames a cars

    inefficiency on the knocking of the engine,

    he might be tempted to muffle the sound,

    masking the real problem.
