Brains Wired for Stories: Why Anecdotal Evidence Can Trump Scientific and Rational Argument
Posted by: Robert Sandberg in Culture, Science, Theory, tags: anecdotal evidence, brain research, evolutionary biology, Michael ShermerIn his recent Scientific American article, Michael Shermer brings out some facts that may explain why and how untested stories—theories in search of an hypothesis, if you will—can trump scientific reasoning. I think that some of the facts about brain functioning that Shermer discusses also provide an insight into possible reasons for why the conflict between science and religion and other mythic types of thinking has persisted for so many centuries and appears set to persist for many centuries into the future.
Here is a quote from the article; you can read more via the link that follows;
We have evolved brains that pay attention to anecdotes because false positives (believing there is a connection between A and B when there is not) are usually harmless, whereas false negatives (believing there is no connection between A and B when there is) may take you out of the gene pool. Our brains are belief engines that employ association learning to seek and find patterns. Superstition and belief in magic are millions of years old, whereas science, with its methods of controlling for intervening variables to circumvent false positives, is only a few hundred years old. So it is that any medical huckster promising that A will cure B has only to advertise a handful of successful anecdotes in the form of testimonials.
