People are losing their heads out there because they don't understand how to interpret studies.

The most infuriating offenders are the media, who have been irresponsible with the presentation of clinical study results. They'll take the results of an observational study and herald it as some revolutionary insight, when in reality the doctors, nurses, and pharmacists interpreting these results are saying "hmm okay, well let's be cautious in our approach and wait for other studies to be done".

Clinical practice should never change, and has never changed (to my knowledge) from the whims of a single OBSERVATIONAL study. But outside medical circles, people will see the results they want to see, and never look past the first 10 words of a headline.
