this is a question that as a trainee psychologist i have pondered for a while …. what is the file drawer phenomena and why is such a problem when it comes to publishing major research.
the file drawer problem/ phenomena which was coined by Robert Rosenthal in 1979, is to do with publication bias ; essentially it draws on the issue which arises when researches reject their null due to the statistical insignificance of the results thus leading less likelihood of their data being published. these negative or inclusive results often never reach the public reasachers , editors, pharmaceutical companies and medical journals are wary of publishing such data which may go against/ contradict common belief. this in my eyes is a major problem as it shows a direct representation of the data field thus leading to direct problems when it comes to continuation if experiments or extreme bias of data. http://www.ma.utexas.edu/users/mks/statmistakes/filedrawer.html
the file drawer problem has major implications when it comes to question validity as the effect reduces validity: the literature produces by the file drawer effect is largely unrepresentative of the population of the studies for example Merck’s research on Vioxx (arthritis drug) had the results that showed that the drug wasnt as effective. this research is deretimental both those adminstration and taking the drug as the pseudo result gives an inaccurate image of its true effect as it largely distorts the data thus giving a bias slant on the results.
Iyangar and Greenhouse in 1988 suggested a plausible way of fixing publishing bias; the sensitivity of effect size( 0.05). as this scale can directly show the level of significance an entity posses, thus creating a stricter more efficient presentation of the data without ruling out haf he results ……… the more stringent the alpha level , the better the test of significance is. http://projecteuclid.org/DPubS?service=UI&version=1.0&verb=Display&handle=euclid.ss/1177013012
to conclude in my opinion the file drawer effect is an out dated practice which should be replaced for a method that best equips the psychological community.
