#141 Balanced Examination of Positive Publication Bias

Dr. Mark Ramos will examine the conventional view that positive publication bias, favoring statistically significant findings, is inherently detrimental to research quality. By exploring theoretical models across varied assumptions about hypothesis truth values, he will show that such bias can substantially increase the proportion of published true positives while only modestly inflating false positives, provided studies maintain reasonable significance and power. When researchers and publishers act competently and in good faith, positive publication bias may enhance rather than undermine the value of the published literature.

Dr. Mark Louie F. Ramos is an Assistant Research Professor of Health Policy and Administration at The Pennsylvania State University. He completed his doctorate in Statistics at the University of Maryland Baltimore County and received postdoctoral training at the Biostatistics Branch of the National Cancer Institute. Prior to this, he was a tenured faculty member at the University of Santo Tomas, Manila. His research interests includes both statistical methods development in areas such as multiple testing and efficient sampling, and multidisciplinary projects involving large, complex datasets such as the United Kingdom Biobank, the National Health and Nutrition Examination Survey, and the United States Military Health System. He has taught mathematics and statistics subjects for over 20 years.
