Peter Doherty won a Nobel Prize for his co-discovery that T-cells must recognize both virus and MHC antigens on the cell surface to kill virus-infected cells. He continues in his immunological research. But he is making perhaps an even greater contribution by authoring books that explain the process and uses of science to both scientists and nonscientists.
“The Knowledge Wars” is written for the non-scientist (though there is much to learn for all), examining and explaining the culture of science through the prism of environmental change. Rather than another tedious description of the scientific method, he explains the culture though history, both the way knowledge is defined and publicized, and the times the scientific culture has been perverted by fraud or greed or stupidity. Doherty makes it clear that scientists are human, that anyone can be a scientist (“And don’t think you have to attend a fancy school or Ivy League university….”, and that plenty of non-scientists are contributing in a major way to scientific knowledge. He does this without being patronizing, using the huge amounts of vital data gathered by birdwatchers as an example of science that could not be done without non-scientists.
But knowledge is power, and knowledge becomes a tool for those who want power. So politicians, individuals, and corporations whose profit or loss depends on data will do their best to obscure the public message and promote the interpretation of data that they want. Doherty explains how layfolk can interpret these coded messages, and he added an appendix with advice on how to judge the credibility of particular scientists via web information, and to read a scientific paper.
Knowledge is power!
