Category: Bad Moves

Bad Moves was a series written by philosopher Julian Baggini detailing the various ways in which arguments are often made persuasively but badly. It formed the basis of a book, The Duck that Won the Lottery and 99 Other Bad Arguments, which has now been published by Granta in the UK, and will be published by Plume in the US soon.

  • Post hoc fallacies

    I used to be a bad boy, but since I got the number I’ve calmed down and
    become more focused on my religion. I believe it is a sign from God, and that
    the number was made for me. It has brought me so much luck it is unbelievable.
    Sulayman Ahmed, Manchester Metro, 13 September 2002

    Unbelievable indeed. What is this amazing power that has turned Mr Ahmed’s
    life around? The answer is a lucky telephone number. Ahmed paid £5,000
    (about $7,500) for a telephone number which contained a lucky sequence of figures
    based around 786, which in Arabic numerology apparently represents the holy
    prayer Bismallah al-Rahman al Rahim.

    Since owning the number, friends and family have been "amazed at the transformation"
    in Ahmed, according to the Manchester Metro. What exactly is the nature
    of this transformation? Details are sketchy. The only specific change of luck
    mentioned in the report is that "he has been relentlessly pursued by women
    desperate to go on dates with him." None of these women were available
    for comment.

    It seems, however, that the luckiest thing about the number is that Ahmed is
    going to be able to sell it on for even more and "start buying property".
    Talk about selling the goose that lays the golden eggs!

    Let us suppose that, in fact, Ahmed has been on a lucky streak since buying
    the number. Does that prove it possesses magical properties? No it does not.
    The reason is simple enough, and those who think otherwise are committing a
    common error known as the post hoc fallacy.

    Here’s how it works. Think of a conditional statement of the form "If
    X, then Y", such as "If this is a lucky number, then owning it will
    bring me luck". This is clearly the kind of reasoning which Ahmed engaged
    in before buying the number. What happens if Ahmed actually enjoys good luck
    after buying the number is that he thinks this shows the truth of what is in
    the "if" clause: "This is a lucky number". But it doesn’t
    because it is not true that he would have enjoyed the good luck only if the
    number were lucky. There could be other explanations. Luck is distributed randomly,
    most of us think, and at any given time there is always a chance that you will
    enter into a lucky streak. So the subsequent run of good luck can never prove
    that what came before it was the cause of the good luck.

    The mistake is even easier to see in other examples. Imagine we are watching
    a football match and I say, "If I scratch my leg there will be a goal in
    the next hour". You would not think if there was in fact a goal and I had
    scratched my leg that the scratching was the cause of the goal. You’d rightly
    see that the fact that the "then" that followed my "if"
    actually happened does not show that my scratching my leg caused the goal.

    It is remarkable, however, the extent to which people fall for the fallacy.
    No matter how little evidence there is of actual causal power, people are remarkably
    quick to attribute causal powers to things that occurred before something else.
    Many superstitions start this way. Someone wears a hat for the first time and
    that day their football team wins. From that day on the hat is their lucky hat.
    "I wore that hat and then my team won, so if I wear this hat my team will
    win." It’s very poor reasoning which is strangely compelling.

    What is also amazing is the extent to which people are blind to other much
    more obvious explanations. In the case of Ahmed, for example, he could hardly
    have been indifferent to his religion when he bought the number, since he parted
    with £5,000 for the number on the basis of its religious significance.
    So saying that having the number is the cause of his renewed interest in religion
    seems to confuse cause and effect. And being convinced of its luck would certainly
    have given him a certain confidence that could translate into more success,
    with women and in other areas of life.

    It’s a simple explanation but for some reason many prefer to think the alleged
    but unsubstantiated "transformation" in Ahmed’s fortunes is down to
    a number. People are indeed strange.

  • If I don’t do it somebody else will

    "If we want to stop the defence industry operating in this country,
    we can do so. The result incidentally would be that someone else supplies
    the arms that we supply."
    Tony Blair, 25 July 2002 (Source: The Mirror)

    How many times have we heard people justifying ethically dubious actions using
    this kind of argumentative move? The logic is clear enough. My action has consequence
    X, which you find objectionable. But if I don’t undertake that action, someone
    else will, and so consequence X will still come about. So there’s no point in
    criticising me for undertaking this action, because that won’t prevent the consequence
    you object to from coming to pass.

    There is a respectable form of moral theory which does say that consequences
    are what determine the rightness and wrongness of actions. But even these theories
    cannot justify this form of argument. Consequentialist theories say that an
    action is wrong if it has bad consequences and right if it has good ones. But
    that means if a person does something with a bad consequence then that action
    is wrong, period. It is not made okay because if they don’t do it someone else
    will.

    If this mistake is clear enough, why then does the argument have a curious
    kind of appeal? One reason is plain wishful thinking combined with self-interest.
    We most often use or hear this kind of argument when someone has something to
    lose by not doing the dubious action, or something to gain by doing it. Therefore
    pure self-interest can make us cling to any justification that seems to make
    our action justifiable. We have a strong desire for our action to be morally
    sound and this makes us accept justifications which, if we were thinking about
    them clearly, wouldn’t pass muster.

    A second explanation is more charitable to those who invoke such arguments.
    It is natural and probably right to think that the morality of actions is in
    some way tied to how they contribute or do not contribute to making the world
    a better place. So in some sense the question, "Will the world be any better
    if I do or do not do X?" is a perfectly good one to ask. But in answering
    it we need to think not only about the net result of our actions when combined
    with those of others but also about our contribution to that result. It may
    well be that the world will not be any better if I refrain from doing something
    bad. But if it is I who does that bad thing rather than someone else then I
    am the one who is responsible for what happens. I am not less responsible because
    someone else would have done it. The fact is that I did do it and so must carry
    the blame.

    And this is in fact how we usually do judge people morally. For instance, a
    group of young men comes across a solitary old person and one decides that one
    of them should rob him and this young man cannot be dissuaded. Does that then
    mean that if one of the other two goes ahead and mugs the old man that he would
    be blameless for the crime? The idea is surely absurd.

    Similarly, in countless repressive regimes people have been tortured, raped
    and even exterminated in death camps. For any given individual involved in those
    atrocities, it is almost always the case that if they hadn’t done it someone
    else would have. But that does not make their actions permissable. (We may feel
    some sympathy for people who were forced to choose between undertaking horrible
    acts and being punished or even killed themselves, but these are factors which
    mitigate our judgement of the wrongdoing. They do not render the wrongdoing
    right.)

    So when it comes to arms dealing, the fact that if Britain doesn’t do it other
    countries will is not enough to justify it. What we need to know is whether
    the arms dealing is morally justifiable in itself. Like magicians’ tricks, the
    argument fools us into looking away from where the real sleight of hand is taking
    place.

  • Slippery slopes

    Implanting tracking devices provides a very frightening vision for the future.
    … This would be used initially for sex offenders, but we would soon find
    that other marginalised groups, such as asylum seekers, would find they were
    forced to have implants.
    John Wadham, director of Liberty. (Source: Observer, 17/11/02)

    The idea of implanting tracking devices under the skins of criminals is, with
    good reason, a controversial one. No other punishment in Britain involves altering
    a person’s body. Some may even see it as requiring a form of mutilation, in
    the strict sense of the word, and that therefore it is an example of the kind
    of "cruel and unusual punishment" that infringes upon a person’s basic
    human rights. These rights, some argue, are also breached merely by the fact
    that an offender with an implant will have his or her movements tracked 24/7.

    These arguments may or may not be compelling and they need to be weighed against
    the arguments in favour of the implants. One of these is that the implants may
    actually give the offender more freedom, since the alternative is to be kept
    under lock and key. Perhaps it’s better to be out of prison and under surveillance
    than in prison.

    There are clearly serious issues and debates surrounding the proposed tagging.
    But the concerns raised by the director of the civil liberties campaign group
    Liberty do not address them. Instead of tackling the key questions head-on,
    he invokes the spectre of a slippery slope: if we allow sex offenders to have
    implants, then before we know it, implants will be everywhere.

    The problem with slippery slope arguments is that they make the location of
    what is contentious unclear. In this case, we need to ask: is it problematic
    that sex offenders have these implants or is it only a problem if the use of
    implants is extended to other groups in society? If it is problematic for sex
    offenders to have the implants then we do not get to the root of the problem
    by thinking about what other groups of people might be next in line for them.
    If it is wrong, it is wrong regardless of whether the technology is extended
    or not.

    But instead of focussing on the actual wrongness of the action under debate,
    slippery slope arguments shift our focus to its unacceptable extensions. In
    the implant case, the goal is to make us oppose implants because we don’t want
    to see them in asylum seekers, not to make us realise how terrible it is that
    sex offenders have them. So they avert our concentration from what is really
    at issue and make us look elsewhere.

    A slippery slope argument can carry some weight if there is a high probability
    that the unacceptable consequence will in fact happen, and is actually unacceptable.
    The problem is that in most slippery slope arguments there is no such demonstration.
    Wadham’s claim is simply an assertion. There is no particular reason to suppose
    that implants will be extended for use with asylum seekers. (It is interesting
    that he talks about "other vulnerable groups", thus classifying sex
    offenders as a "vulnerable group". In some senses sex offenders are
    vulnerable, but not many people would agree, if it were stated directly rather
    than obliquely, that they form a vulnerable group comparable to asylum seekers.)
    But unless we are given good reason to suppose implants would be extended to
    other groups we would not want them to be extended to, the slippery slope doesn’t
    work. It is not enough to say, "If you tolerate this, asylum seekers will
    be next." One has to show that asylum seekers will in fact be next, or
    at the very least that there is a good chance they will be.

    Ironically, the famous slippery slope argument just alluded to is arguably
    not an example of the genre at all. Republican posters in the Spanish Civil
    War showed Nationalist bombings and proclaimed, "If you tolerate this your
    children will be next". However, the real force of this poster was only
    partially due to its depiction of the possibility of what might happen next.
    What the poster did above all was to make us realise the unacceptability of
    the nationalist bombings themselves, by making us imagine what it would be like
    if our children were the victims. So just because an argument has the apparent
    form of a slippery slope argument, that doesn’t necessarily mean it exhibits
    all its failings.

    When confronted with a slippery slope argument, two questions should be asked.
    First, is the practice being objected to in itself objectionable? If it is,
    then the foreseen extensions are irrelevant. If implants for sex offenders are
    wrong they are wrong, and it is an irrelevant distraction to start talking about
    implants in other groups of people. If bombing Spanish towns is wrong, it is
    irrelevant that it would also be bad to bomb British ones. If the practice is
    not objectionable in itself, we then need to ask, if we start down this road,
    is it likely that the practice would be extended to situations where it was
    objectionable? Only if it is will the slippery slope argument carry any force.
    And even then, that may only provide reasons for creating safeguards to prevent
    the unwanted extension. It cannot form a direct objection to the practice itself.

  • Beguiling wisebites

    The poor sell drugs so they can buy Nikes and the rich sell Nikes so they
    can buy drugs.
    from £9.99 by Frédéric Beigbeder (Picador, 2002)

    It is widely lamented in serious circles that we live in the age of the "soundbite".
    Nuanced arguments have been replaced with rapid-fire rhetoric for a generation
    with no attention spans. The short, sharp, memorable phrase is king.

    "Soundbite" is however a term of abuse rather than a description
    of a single phenomenon. If you approve of what is said pithily and memorably,
    all of a sudden it is not a soundbite after all, but an aphorism or a "pearl
    of wisdom". Quotations lifted from literature, film or theatre are often
    dignified in this way. In order to emphasise their shared features with soundbites,
    let us call them "wisebites".

    What is ironic is that the very people who often scorn the soundbite for its
    shallowness often fall for the wisebite which is equally vacuous if not more
    so. Take, for instance, the quotation above from Frédéric Beigbeder’s
    novel. One reviewer of the book selected it especially as an example of the
    writer’s brilliant ability to hit the nail on the head. But the wisebite falls
    apart at the slightest examination. It just isn’t true.

    Of course some poor people sell drugs in order to afford more consumer goods
    and some people working for multinationals are drug takers. But that’s not really
    what the wisebite implies. Rather, the wisebite suggests that there is a kind
    of vicious circle of consumption: that the rich create a need or desire for
    the poor to acquire consumer goods so that they themselves can fund their drug
    habits, which are in turn supplied by the poor. Capitalism is thus a kind of
    self-perpetuating mechanism for keeping the poor poor and the rich stoned. This
    may be true in an extremely crude satire on advanced capitalism written by a
    naive member of the Socialist Workers Party youth wing, but does anybody really
    believe it accurately describes the true, complex relations between drug users
    and suppliers, multinationals and the poor?

    Is it even true that the poor generally sell drugs? Drug dealers are often
    from poor backgrounds but they themselves are often very wealthy indeed. Many
    of their drugs are in fact sold to the poor and it is their addictions which
    keep them poor. But then the idea that the ex-poor are exploiting the still-poor
    doesn’t appeal to the intellectual classes as much as the idea that the poor
    are victims of greedy corporations.

    Strip away the nonsense from the wisebite, then, and you are left with the
    truism that the poor do aspire to acquire material goods and that this desire
    is partly fuelled by the producers of these goods. Furthermore, some rich people
    take drugs. That really does not leave much of the original sentiment intact.

    Compare this with a bona fide soundbite. British premier Tony Blair is fond
    of saying "No rights without responsibilities". Put like that, the
    soundbite is too simplistic. Newborn infants, for instance, have rights without
    responsibilities. But take away the obvious exceptions and at least there is
    a serious point being made by the soundbite. If we are to have rights in a society
    then certainly people have responsibilities to uphold them or not to infringe
    them. The general existence of rights does entail concomitant responsibilities.

    In this battle of the bites, it is thus the derided soundbite which emerges
    the stronger and the celebrated wisebite turns out to be hollow. It seems we
    are as ready to be beguiled by the false but wise-sounding "aphorisms"
    of the writer, poet or intellectual as we are to dismiss the soundbites of the
    politician. Their relative merits rarely come into play.
