Here is an interview with Peter Wilmshurst, cardiologist, researcher, and courageous advocate for doing science better. He discusses some of the enormous pressures that can be brought to bear to shape the outcomes of industry research, and how, as a…
Introduction to the New Statistics
The online community and blog for ITNS
Month: September 2016
Sample sizes are too dang small…
Here’s another incredible paper by John Ioannidis and associates. This one uses text mining to examining the statistical results of thousands of cognitive neuroscience and psychology papers. It finds that sample sizes being used remain far too small: the typical…
More on the dangers of p values
Here is an interesting new paper in which experienced researchers were asked to make judgements about research results expressed using the NHST approach (p values!). A free copy of the paper is here, but it is easier to read the…
NIH and the push for better science
Science is vital and it is also big business. In the U.S., one of the biggest founders of scientific research is the National Institute of Health (NIH). As the NIH writes the checks, you can imagine that it finds the…
Is Science Sick? Bob’s talk on the replication crisis
Here’s a video of a talk Bob gave to first-year honors students about the replication crisis and what lessons it might have for their own lives. Enjoy!
Good research in the service of more effective activism
Research can be vitally important, helping shape how we see the world and the policies we enact. Here is an example of an applied research lab aiming to use applied research to figure out the most effective ways to lobby…
Get involved: registered replication project on “professor priming”
Registered replication reports are a new initiative sponsored by the APS where labs around the world collaborate to conduct a large-scale, precise replication of an important finding in psychology. The really cool thing about these projects is that they are…
Studying statistical cognition is essential for improving rigor and reproducibility. You can participate! Here's a link to a short study of statistical cognition: https://t.co/EKAAdbkQUN
This study is being conducted by @lonnibesancon and @jouni_helske .

Finally had time to check out @russpoldrack on reproducibility in neuroscience:
“First, we must acknowledge that we have a problem, and that all of our careers have benefitted from the research practices that we now realize to be questionable.”
Amen.

Thanks, Nick! It was great to visit with the MCB grad students and postdocs. Lots of energy for planning strong research.
Went to a phenomenal seminar about sample-size planning by Bob Calin-Jageman @TheNewStats. I have a LOT of work to do in how to plan experiments and determine relevance (not P values!) of results. He would make a great speaker at any department! Check out https://t.co/U5Ztw630a0
New preprint.
Adversarial team collaborated to specify when facial feedback effects should most reliably emerge. 2 pilots revealed evidence for the facial feedback hypothesis. Next, 18 labs (17 countries) will test whether these findings are replicable.

Oh sh-t. Why can't we have nice things?
The study showing handwritten notes are superior to typed notes fails to replicate https://t.co/2RdBOwVh9O
In my first pre-print, working with @lakens we present 2 methods from clinical/health research & show how they can be used in basic psych research to determine the smallest noticeable change/difference & thus the SESOI for research questions interested in noticeable change. 1/2 https://t.co/udPb9UomF1
