Don’t believe everything you read – even if it has been published in a reputable scientific journal:

“Dr John Ioannidis of the University of Ioannina in Greece, writing in the Journal of the American Medical Association, recently analysed 45 well publicised studies from leading journals appearing between 1990 and 2003.

His conclusion: the results of approximately one third of these studies were flatly contradicted or significantly weakened by later work.”
