To review current scientific practices that elevate false-positive rates and provide practical guidelines for improving research reliability.
Review of scientific practices, statistical pitfalls, and psychological biases affecting the probability of false-positive conclusions.
Analysis of key drivers of irreproducibility, including small sample sizes, publication bias, researcher flexibility, and pseudoreplication.
Identified that false-positive findings proliferate due to small sample sizes, an excessive focus on novel results, flexible data analysis, multiple testing, and unaccounted pseudoreplication.
Demonstrated that systemic publication bias favoring statistically significant outcomes undermines the validity of meta-analyses and hinders hypothesis falsification.
Proposed actionable mitigation strategies, including study preregistration, observer blinding during data collection and analysis, comprehensive reporting of all findings, and dedicated replication efforts.
