50、veral decades, there has been an extensive and organized campaign intended to generate distrust in science, funded by regulated industries and libertarian think tanks (自 由主义 智囊团)whose interests and beliefs are threatened by the findings of modern science. In response, scientists have tended to stres

51、s the success of science. After all, scientists have been right about most things, from the structure of the universe to the relativity of time and space.Quoting successes isnt wrong, but for many people it s not persuasive. What is typically declared to be the scientific method - develop a supposit

52、ion, then design an experiment to test it -isnt what scientists actually do. Science is active so that new methods get invented and old ones get abandoned. The scientific method doesnt always work. False theories can produce true results, so even if an experiment works, it doesn t prove that the the

Scientists are human. But if we look carefully at historical cases where science went wrong, typically there was n

57、o agreement reached by all. Some people argue that we should not trust science because scientists are always changing their minds. While examples of truly settled science being overturned are far fewer than is sometimes claimed, they do exist. But the beauty of this scientific process is that it exp

58、lains what might otherwise appear paradoxical （矛盾的）：that science produces both novelty （新颖性） and stability. New observations, ideas, interpretations introduce novelty: trans-formative questioning leads to collective decisions and the stability of scientific knowledge. Scientists do change their mind
