The undergrowth of science Book

Walter Gratzer's themes in the stories he relates in this book are collective delusion and human folly. Science is generally seen as a process bound by rigorous rules, which its practitioners must not transgress. Deliberate fraud occasionally intrudes, but it is soon detected, the perpetrators cast out and the course of discovery barely disturbed. Far more interesting are the outbreaks of self-delusion that from time to time afflict upright and competent researchers, and then spread like an epidemic or mass-hysteria through a sober and respectable scientific community. When this happens the rules by which scientists normally govern their working lives are suddenly suspended. Sometimes these episodes are provoked by personal vanity, an unwillingness to acknowledge error or even contemplate the possibility that a hard-won success is a will o' the wisp; at other times they stem from loyalty to a respected and trusted guru, or even from patriotic pride; and, worst of all, they may be a consequence of a political ideology which imposes its own interpretation on scientists' observations of the natural world.
