There was an article a few months ago, I think on HN, with a headline to the effect of "Scientists link <some chemical> to <some mental health issue>". Clicking through a few links to get to a more authoritative source, and it sounded more like "Our results show a correlation with a larger uncertainty than we'd like to see, and this contradicts a similar study done previously". People need to understand the statistical nature of these studies and what conclusions that should be drawing. IMO an understanding of correlation vs. causation, factors, levels and control groups, etc. should be part of any decent education (i.e. well before college). We can't expect mainstream media to help of it's own accord.
