Professors from universities in California and Finland conducted a study that came to the conclusion that there are too many studies. Sadly, as long as people are handing out money for studies, regardless of how ludicrous or useless, professors and scientists will be lining up with their hands out.
To me, this study is the antithesis of valuable research. If you believe (or suspect) there are too many studies, isn't accepting money to study studies proof that many studies are not designed to enlighten and inform, but rather to line the pockets of the researchers? It seems to me that the world would be better off if the funds for that study had been used to fund research devoted to finding a cure for cancer or feeding the hungry.
