Facts about publication bias

In 1995, only 1 percent of all articles published in alternative medicine journals gave a negative result.  The most recent figure is 5 percent negative.

That is from Ben Goldacre’s excellent Bad Science, right now available only in the UK.  This is one of the best books I have read on how to think like a scientist and how to critically evaluate evidence and also on why we don’t have a better press corps when it comes to science.

I thank Michelle Dawson for the pointer to the book.
