Overview

Mathematical modeling demonstrates elevated rates of false-positive claims in psychological research, highlighting systemic publication bias against the null hypothesis.

Key Points

To evaluate the systematic consequences of prejudice against accepting the null hypothesis across researcher behavior and editorial decision-making in psychological science.
Constructed a mathematical model simulating the research-publication pipeline, including problem selection, study continuation or abandonment, and editorial acceptance criteria.
Informed model input parameters using survey data from social psychologists and corroborated model predictions against published psychological case studies.
The simulation revealed a dysfunctional publication system that generates very few published papers on questions where the null hypothesis is true.
Among published manuscripts addressing true null effects, the model indicated that an excessively high proportion erroneously reject the null hypothesis.
