From abstract

Of these, 7 (16%) were contradicted by subsequent studies, 7 others (16%) had found effects that were stronger than those of subsequent studies


Isn't this how science is supposed to work?

It would be strange if medical studies always got the same result. There is always going to be differences. If a study finds a slightly different result, or even if a study contradicts a previous study, it does not necessarily mean that the original study was flawed. There is so much variation that is difficult to control for. Maybe the first study was conducted when there was a flu epidemic was going on, and people were generally healthy during the second.

Saying that, it's worrying that some pharmaceutical companies are being dishonest in their publishings. Some have conducted loads of trials, but only reported the most positive ones. Sometimes they haven't published results regarding side effects. As someone who loves science, I find this disgusting.

This reminds me of Todd Snider's great song, Statistician's Blues.

Well since this study shows that one third of studies are wrong, how do we know that this study is accurate?

Sorry, I just couldn't resist.

Yeah but medical studies or not, aren't we always going to get some percentage of research that proves to be ... not so good. After all we expect them to be peer reviewed and then repeated and so some findings are going to contradict others.

Shouldn't we be expecting similar types of statistics for research in all fields?

But sooner or later, all of the failed studies are known for what they are. There is a bit of knowledge to be gained from them, even in their failure. I am reminded of Archeoraptor and National Geographic's blunder.

There a great documentary about that. I'm impressed by the work done on both the forgers and palaeontologist sides.

Indeed. It was a masterful fraud. And the great part about it is that it is still a valuable find in that it was pieced together from two, previously unknown species.
