Check for the Appropriateness of Comparisons Before Drawing Conclusions • • • • • (bewertet mit 3 von 5 Punkten) Alle meine Rezensionen ansehen (TOP 500 REZENSENT) Rezension bezieht sich auf: Economic Facts and Fallacies (Gebundene Ausgabe) Economists are driven crazy by the misleading conclusions that journalists and politicians draw from using numbers in the wrong way. Dr. Sowell uses this book as an opportunity to challenge some of the conclusions that abound concerning cities, male-female incomes, academia, middle-class incomes and size of the group, racial differences, and characteristics of the third world versus the developed countries. It also points out that these errors have consequences in misallocating resources that could be better applied elsewhere. If you have never sat through a class on what it takes to make a valid comparison, this book is one long essay on that point. That's the meta-message. The micro-messages relate to suggesting that problems aren't as large and serious as they seem from frequently quoted statistics. I thought that Dr. Sowell was at his best in describing mismeasurements about middle class income in Chapter 5. In several of the other chapters, especially Chapter 3, it seemed to me like he was over arguing about statistics at the expense of drawing the right conclusion from looking at the context of what is going on. There seemed to be a desire to show virtuosity that appeared to get in the way of answering the question posed in the chapter. Of course, it's absurd to say that if half of an employer's employees are women that management positions should also be 50 percent female. But if the management positions are only held by women 13 percent of the time, it does seem like something else might be going on (including possible discrimination against women). Dr. Sowell would prefer to leave the argument at the apples and oranges stage. Some of the historical comparisons are interesting (such as how the percentage of highly educated women in the workforce has changed in the last 110 years). Parents who resent the high tuition their children's colleges charge will resent those charges even more after understanding more how those high prices are reached and maintained. The book would have been a lot better if it had included a more solid description of what questions we should be asking and answering in each of these areas to understand what's going on. Without that fully developed foundation, even after reading this book many will be at sea in understanding what's going on in society and the world. Eine Rezension von Ein Kunde vom 17.
