On 3 May 2016 guest speaker Michèle Nuijten will give a lecture: 'Judging the quality of research: Detecting and preventing (human) errors in statistics and the Replication Paradox'.
Huge quantities of articles are published every day. As scientists, we should be quickly able to judge whether an article reports trustworthy and valid results. Unfortunately, scientists make many errors in reporting and evaluating statistics. Michèle Nuijten’s research focuses on these “Human factors in statistics”. For example, she developed a module in R called “Statcheck”, which can be used to automatically detect statistical errors in articles. Using this software, she found out that statistical inconsistencies show a systematic bias towards reporting statistical significance.
Furthermore, we have to estimate whether the effect we are interested in actually exists based on a body of existing literature. Researchers tend to believe that “more information is always better”, and thus that replication studies are automatically valuable. However, Michèle Nuijten’s research on the “Replication Paradox” has shown how replications can do more harm than good, and how we are researchers are not very good at judging this…
These tendencies are of course detrimental for the health of the literature in a scientific field. However, how can we as readers detect these errors, what can we do to prevent them, and how can we learn to better evaluate research? In this talk, Michèle Nuijten will discuss the detection, causes and characteristics of false positives in the literature and the effects of the Replication Paradox.
Michèle Nuijten is a PhD student at Tilburg University. Her work on the Replication Paradox was featured in the Volkskrant and Retraction Watch, she was a co-author on “Estimating the reproducibility of psychological science” project, which was recently widely discussed in the international media and published in Science, and was also nominated for the VIVA400 in 2015 (for women who achieved something remarkable).
