写论文上关于哪些写，哪些不写的问题，其实研究伦理上规定得并不严格，很多都是作者自行判断。所以那些不好的或者不显著的成果往往都沉眠在抽屉之中，也许就只有刚好那5%显著的结果被发表出来也说不定。哎哎，这么说还真是自己给自己找堵啊。

The file drawer effect, or file drawer problem, is that many studies in a given area of research may be conducted but never reported, and those that are not reported may on average report different results from those that are reported. An extreme scenario is that a given null hypothesis of interest is in fact true, i.e. the association being studied does not exist, but the 5% of studies that by chance show a statistically significant result are published, while the remaining 95% where the null hypothesis was not rejected languish in researchers’ file drawers. Even a small number of studies lost “in the file drawer” can result in a significant bias.[5].

The term was coined by the psychologist Robert Rosenthal in 1979.[6]
