ISP209s9 Lecture 9 -4- The Scientific Method • Science – No theory can ever be proven true. We are always looking for theories that work better. • Pseudoscience (not bad, just not science) The hypothesis is not at risk. If data does not agree with the hypothesis, then the data is assumed to be wrong. – Some facts are ignored. – Exploit the controversies and inadequacies in a competing theory. – Portrayed as an underdog being punished by the scientific establishment. – Reliance on fear and other emotions, or reliance on a lack of knowledge – People who do pseudoscience usually do not publish in normal scientific journals.
