First and foremost, as an avid fan of the topic of Statistics in general, I felt compelled to read this book. I had read another of Joel Best's book, More Damned Lies and Statistics: How Numbers Confuse Public Issues, and it was shocking to say the least. In the process of deciding which book I was going to read I contemplated between How to Lie with Statistics by Darrell Huff, but I felt that book was more of a `pocket-guide' instead of a dense book. Also, I wanted to read a book that was perhaps more current, in terms of publication than Huff's book. Published in 2001, Best's book shows some current social statistics, which perhaps may be more relevant in our time period.
Upon finishing Best's book I notice that it was jam-packed with information that the average person wouldn't know about every day statistics. For example, he touches on the topic of AIDS statistics, and prostitution statistics, in an effort to show that the statistics are skewed. In my opinion, I think it was very appropriate that a sociologist wrote this book because, it is virtually a reflection of how society reports, views, and interprets statistics. It is mind-stirring when he shows that statistics on the same subject cannot be accurately compared if they are from a different time-period. Due to the fact that Ceteris Paribas is not present when comparing statistics from different time periods, in essence they are like comparing, as Best puts it, "apples to oranges".
Also, another startling area of the book is when Best describes the misunderstanding and the fallacies that occur with reporting and interpreting statistics. For instance, in chapter three of his book, he reports that an estimated 150 thousand women are diagnosed with anorexia, or better known as the most common eating disorders among young women. While that may be a `good' statistic, people began to misinterpret that statistic with the conclusion that 150 thousand women die because of anorexia. This fallacy occurred because people assume that anorexia can be fatal, and since 150 thousand of them had it, they then assumed all of them died. This, as Best puts it, is far from the truth, as less than 100 of them actually die (roughly around 70). He gives other examples of common social problems with statistics and shows that a post-hoc fallacy is very common in a world where people are rather naïve when it comes to statistics in general.
Perhaps the notion of statistics causing social problems is one too radical for the average American to recognize. How can statistics be the cause of problems? Best also addresses that a `bad' statistics can cause social problems. On page fifty, Best explains how "measurement decisions are hidden" and often times some statistical reports ignore controversies about measurement, and even well-established measures can be controversial. Not surprisingly, some of the measurement decisions, are just plain wrong. The reports to some statistics that the media feeds us are just completely wrong.
Best mentions another rather relevant problem; "questionable definitions". He cites that often times the definitions for a particular statistic are vague and can easily be manipulated. He asks us to consider the flurry of media coverage about `epidemics'. We must ask ourselves, what is an epidemic? More importantly, how does the particular author reporting the statistic define what an epidemic is? Making a vague statement like that can be very dangerous to society. It can spread false fears, and in essence, a misrepresented sense of reality. Another important factor when determining if a statistic is manipulated is based on sample size. Best gives us examples of how a small sample size is really a poor basis for generalizations. For example, let's consider that I ask 3 women to give their view on abortion and they can either choose pro-life or pro-choice. My results are going to be 0%, 33.3%, 66.6%, or 100%, depending on their responses. However, it is absurd to think that a true conclusion can be drawn from such a small sample size.
I feel this book is a great book to read, not only for entertainment purposes, but also as a preventative measure regarding everyday statistics that we encounter. In his final chapter "The Critical Approach", he requests that we use a method of critical thinking when viewing statistics. The author encourages us as a society, to interpret statistics in a skeptical manner, but warns us not to be cynical. We cannot just take statistics at face value. I feel that we hold a responsibility to inform ourselves and view new information with a skeptics view. It is vital to prevent social chaos by swallowing every bit of numbers from the media, politicians, and activists. I think that perhaps if society took a less naïve approach to things of this nature, then we would not have so many "stat wars" in our society. Finally, the most important part of the book is that it encourages the reader to take a skeptic view on social statistics. I recommend this book to virtually any active member of our culture.
