When pseudoscience turns into policy

Principal Scientific Adviser, Government of India, Prof K Vijay Raghavan in his post on Indian Science Congress fiasco outlines some instances of harm caused by the pseudoscience influenced policy decisions.
  1. Trofim Lysenko’s (under Stalin and Kruschev) rejection of Mendelian genetics, ruined the study of genetics and plant breeding in’ the Soviet Union, ruined Soviet Agriculture and caused famines through the acceptance of what was, then too, clearly pseudoscience. Millions of lives were lost because of the introduction of a process where Lysenko was complicit.
  2. In South Africa, tens of thousands lost their lives when the President and Health Minister asserted that HIV does not cause AIDS. This has long been recanted, fortunately.
