Bullshitters (2010)

Book Review from the May 2010 issue of the Socialist Standard


Bad Science. By Ben Goldacre. Fourth Estate

In 1986 an American philosopher called Harry Frankfurt wrote an essay “On Bullshit” in which, according to Goldacre who writes a “Bad Science” column for the Guardian, he drew a distinction between lying and bullshitting. A liar knows the truth and seeks to disguise it. A bullshitter doesn’t know or even care about the truth but is out to impress.

Most of those Goldacre criticises in this book are bullshitters rather than liars – though not all, there are some genuine fakes and frauds amongst them. He starts with an easy target, homeopathy, which is patently absurd (as if bottles of diluted water shaken in a particular way could cure anything) but relatively innocuous (drinking diluted water won’t harm you). Some homeopathic practitioners, however, are not and, Goldacre reports, can be very nasty towards critics.

Their argument – and that of all the other ‘alternative’ medicines – is that their treatments work. They certainly seem to in some cases. People do get better after taking the pills or whatever. But the question that needs to be answered is why. Is it because of the pills or is there some other reason? There are a number of possible explanations other than the theory of the ‘alternative’ practitioners. Sometimes the body recovers spontaneously. Some ailments go in cycles, so a bad period will be followed by a less bad one. In others, any therapy, no matter what the theory behind it, will work: any therapy or even sympathetic listening will help. Then there is the ‘placebo’ effect (people getting better because they believe they are being given a certain treatment when in fact they haven’t been) which Goldacre discusses in interesting detail.

Much of the book is devoted to his criticism of popular TV and other ‘nutritionists’, who he identifies as prize bullshitters. Why? Because there is no verified, or even verifiable, evidence for their claims. Some of them may sincerely believe in what they say but their main aim is to make money. Goldacre is quick to add that the same applies to the pharmaceutical companies who are always inventing new ‘syndromes’ for which their pills are the best cure.

Goldacre also criticises scientifically-illiterate journalists who are more interested in a story that will keep readers or pander to their prejudices, so maintaining newspaper or magazine sales, than with the real situation. This can be dangerous as over the MMR scandal as it was because of them that a number of parents left their kids unprotected against measles which they and others later contracted.
The socialist angle on all this is that under capitalism people are forced to make money, one way or another, in order to live and, given this, some will adopt dubious and even dangerous ways of doing this. And that there’ll be no snake-oil salesmen in socialism.
