The file-drawer effect refers to the practice of researchers filing away studies with negative outcomes. Negative outcome refers to finding nothing of statistical significance or causal consequence, not to finding that something affects us negatively. Publication bias is also called the file drawer problem, especially when the nature of the bias is that studies which fail to reject the null hypothesis (i. Decisions Revisited: The Effect of the Outcome of Statistical Tests on the Decision to Publish and Vice Versa, The American Statistician, 1995, vol 49 No. Radin is aware of the file-drawer effect, in which only positive results tend to get reported and negative ones are left in the filing cabinet. This obviously can greatly bias any analysis of combined results and Radin cannot ignore this as blithely as he ignores other possible, non-paranormal explanations of the data.
Publication bias, or the file-drawer effect, refers to the possibility of a systemic bias in published research in a field due to over-reporting of positive results. Accumulating evidence, including a report in this issue by Bhandari and colleagues, (see page 477) suggests that commercially sponsored clinical trials are biased toward obtaining positive results. Under pressure for positive results, economists, business and social science investigators are distorting the research record, suggests an analysis of the scientific literature.
What is the file drawer effect? The problem of selective reporting is not limited to students reporting family legends; it is a major problem for researchers as well. The File Drawer Problem is actually related to another serious scientific problem known as the Desk Problem. The reason this is a problem is that, over the long term, if only (or mostly) positive findings ever get published, researchers can get a very skewed picture of how strong an effect really is. Vocabulary words for Research Methods Exam 1 (Literature Review and File Drawer Phenomenon). Includes studying games and tools such as flashcards.
This bias, often called the file-drawer effect because the unpublished results are imagined to be tucked away in researchers file cabinets, is a potentially severe impediment to combining the statistical results of studies collected from the literature. Key words: publication bias meta-analysis file drawer effect statistics. Psychologists are up in arms over, of all things, the editorial process that led to the recent publication of a special issue of the journal Social Psy. This contributes to the so-called file-drawer phenomenon, whereby studies that do find sex differences get published, but those that don’t languish unpublished and unseen in a researcher’s file drawer. When we relegate our non-significant findings to the file drawer, we deny others in the field the opportunity to learn what phenomena do not reliably influence one another.
