Perhaps we can keep on being negative after all. A new paper (linked below) asserts that as much as 50% of scientific studies are actually wrong.
For some, it's the usual culprits, too small of a sample size and researcher bias. Keep with me, I'm not going to start talking about multiple regression, I promise! Anywho, even with larger studies, this paper states that some conclusions are "massaged".
Personally, I think a lot of it has to do with people setting out to prove something and finding the data to support it while throwing away anything that doesn't support their theory. Of course, I could just be saying that because I'm having an absolutely crap day and can only be cynical and pessimistic and now I learn that I'm going to die early because of it!
