\begin{abstract}
Scientists value transparency and reproducibility, but are rewarded for
highlighting the novelty of unexpected findings. This is one reason why
published research findings are hard to reproduce. See, for example, the
recent work done by us and the scientists involved in the Open Science
Collaboration on Estimating the Reproducibility of Psychological Science
(https://osf.io/ezcuj/wiki/home/). When scientists preregister their
research, they are making key decisions without being biased by the data
they collect, which makes standard statistical tests more effective.
Though preregistration is required by law for clinical research
involving human medical studies, it is not widely practiced by most
scientists. We at the Center for Open Science have \$1,000,000 to hand
out as prizes for researchers who publish the results of their
preregistered research. See https://cos.io/prereg We'll be back at 12 pm
ET (9 am PT, 5 pm UTC) to answer your questions, Ask us anything!
Answering questions today: Courtney Soderberg is our Statistical and
Methodological Consultant who advises researchers on best practices in
experimental design and statistical analysis to make their work more
reproducible. Jolene Esposito works with researchers in Africa to to
improve the rigor of their work using the tools we've made, such as the
Open Science Framework (osf.io) April Clyburne-Sherin is our
Reproducible Research Evangelist who conducts workshops to train
researchers on reproducible research methods and open science tools.
David Mellor works on encouraging researchers to preregister their work
on the Open Science Framework. Hello Reddit! http://imgur.com/DpMrjKV
(edits for formatting, picture, our names) Edit 2 PM EST: Thanks for all
of your questions everyone! We've enjoyed talking to you. We will come
back later today to see if any more questions are up. Follow us on
Twitter! @OSFramework%
