Research scams

How often do you come across research studies saying a variety of things? At the time of this writing (mid June 2012) there is a study in the news, that says that taking vitamin D and calcium supplements does not help older women. And another that says Omega-3 fatty acids don't help the brain after all

I did not read the two articles. The reason? I don't know how I can take them with any seriousness anymore.It seems they always say one thing today only to completely reverse their opinions just a few days later.

What is the reason for this inconsistency? Are not these studies properly vetted, especially when they contradict long-established theories? Where is the research community's sense of responsibility when publishing their claims in the media?
Are these studies merely for someone trying to complete their PhD? If so, what a nice way to begin a life of quack doctorship!
And to think of some of them --- I get the feeling, even I could dream up a theory like that. Now if only I were among the "right" crowd, that is entitled to publish their papers in prestigious journals.. and here is one more point: why is Research shielded from "outsiders"? Is it because they have not studied the topic, at least for grades? But look at what the people who "studied" came up with. Indeed, laughable
In my opinion, to have a paper vetted and published there should be no prerequisites. Only sufficient training in the scientific process, that includes all formalities, all formats, and ways to scourge information and access to books/other sources

Come on researchers, I challenge you! Do you have the guts to compete against the torrent of ideas from the general people? Do you really want to take Science to the new frontiers? I very much doubt, because you are all namby pamby self-preservers
