APS just wrapped up. Geoff and I were privileges to help host a symposium on making progress moving the field away from p values towards the New Statistics. Our co-conspirators were fellow text-book author Susan Nolan, Psychological Science editor Stephen…

Getting the whole story: journals could be more encouraging
Even though replication is a cornerstone of the scientific method, psychology journals rarely publish direct replications (though that situation may be changing). Why not? Is it self-censorship, with authors not bothering to conduct or submit such studies? Or is it…
from the APS Convention in Boston
Bob and I are in Boston this weekend for the annual APS Convention. It’s great to catch up, and discuss a million things about ITNS and this blog, and our future plans. Our publisher told us yesterday that early signs…
Confirmatory Research – A special issue of JESP
Catching up a bit, but in November of 2016 the Journal of Experimental Social Psychology published a special issue dedicated just to confirmatory research. http://www.sciencedirect.com.proxy.cc.uic.edu/science/journal/00221031/67/supp/C The whole issue is well-worth reading: There is an excellent guide to pre-registration (ostensibly for…
A cool new journal is Open
APS (The Association for Psychological Science) recently launched its sixth journal: Advances in Methods and Practices in Psychological Science. A dreadful mouthful of a title–why not drop ‘Advances in’ for a start–but it looks highly promising. Maybe it will become…
Publishing unexpected results as a moral obligation for scientists
Amen! A revised European Code of Conduct for Research Integrity now specifically calls on researchers and publishers to not bury negative results. Specifically, the guidelines formulate this principle for publication and dissemination: Authors and publishers consider negative results to be…
What the datasaurus tells us: Data pictures are cool
In various places in ITNS, especially Chapter 11 (Correlation) we discuss how important it is to make good pictures of data, to reveal what’s really going on. Calculating a few summary statistics–or even CIs–often just doesn’t do the job. Many…
Now for some good news: SIPS
The Society for the Improvement of Psychological Science (SIPS) held its first meeting last year, with around 100 good folks attending. Working groups have been–would you believe–working hard since then. The second meeting is 30 July to 1 August, in…
Methodological awakening: backlash against the backlash
Science has had some rough times lately, no doubt. No need to rehearse the many findings indicating that we have some problems that need a fixing. As Will Gervais put it, we’re in the midst of a “methodological awakening”. The…
Replication problems are not competence problems
Why do some replication studies fail to produce the expected results? There are lots of possible reasons: the expectation might have been poorly founded, the replication study could have been under-powered, there could be some unknown moderator, etc. Sure, but…
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
