"The intrusion of ideological concerns into science endangers public health. In this well-informed and balanced account, Finkel demonstrates that especially since the 1980s, scientific findings have often been misrepresented to serve sectarian interests. Avoiding polemics, especially in her discussion of the debate over stem cell research, Finkel surveys several medical issues to show how distortion of science for politically expedient purposes has deprived Americans of health care often readily available in Europe and Canada. The religious right and other conservative groups have pressured politicians to erode women's reproductive freedom and deny federal funding for needle exchange programs (for AIDS prevention), and have made therapeutic marijuana unavailable to those it would benefit. At the other extreme, conservatives' protection of business freedom has left the food supplement industry virtually unregulated. Finkel provides lucid explanations of the public health significance of each topic she presents; then, in language easy for laypeople, she details the surrounding controversies and scientific findings. For most areas she highlights, politicians and local officials have undermined definitive scientific conclusions by yielding to emotional rhetoric, e.g., the FDA's handling of Plan B emergency conception--a form of birth control, not an abortifacient. This is an important book that will benefit all reading audiences. Recommended. All levels." - Choice
