Workshop in Biostatistics

M112 Alway Building, Medical Center

(next to the Dean's courtyard)

DATE: April 20, 2017
TIME: 1:30 - 2:50 pm
TITLE: Measuring scientific bias across disciplines and countries
SPEAKER: Daniele Fanelli
Senior Research Scientist
Meta-Research Innovation Center at Stanford (METRICS)



Science is said to be suffering from a reproducibility crisis caused by growing research and publication biases. How common are these problems in different fields and countries, and have they actually worsened over time? In this workshop I will present past and recent studies that tried to answer this question. I will describe, in particular, two different methods that I have yielded informative results: one based on a very simple and flexible proxy of scientific bias, and one based on second-order analysis of meta-analytical data. I will illustrate the advantages and limitations of each method and I will discuss what the findings obtained using each method can tell us about the integrity of contemporary science.
