Our research group in Bern has been awarded two @snsf.ch project grants! We will hire a number of new postdocs and PhD students. Congratulations to @jamiecummins.bsky.social @malte.the100.ci and @ndevito1.bsky.social whose project deepens the links between @bennettoxford.bsky.social and @unibe.ch

Inhibiting and facilitating conditions of the h̶u̶m̶a̶n̶ smile: a n̶o̶n̶obtrusive test of the facial feedback hypothesis (Strack et al., 1988)

Yay! We took the umbrella observed by @jamesheathers.bsky.social et al. (2016), formalized a version of it, and explored what we can learn from it regarding power and heterogeneity analysis. Article now out at BRM: rdcu.be/eRAyW. Many thx to my coauthors @lbnhr.bsky.social and @renkew.bsky.social!

hurrah! a new preprint*! weee have DAGs! we have Total Survey Error**! WE have MrP (rebranded as RPP)! We have cool plots showing how even high quality random samples can benefit from a good weighting model! What else do you want?! With @ianhussey.bsky.social, @malte.the100.ci, & @ruben.the100.ci

Interested in comparing measurement precision across a bunch of data-sets/administration sites? Tempted to just throw a meta-analysis at reliability coefficients (also known as Reliability Generalization)? Maybe don't, read here on what to do instead: doi.org/10.1037/met0000740 #metasci 1/5

My weekend starts with great news! Our stage 1 registered report received an in-principle-acceptance by @pci-regreports.bsky.social The IPA and manuscript can be found here: rr.peercommunityin.org/articles/rec... Looking forward to start working on the things we planned!

Neuer Job gefällig?

Now accepted at AMPPS: It's not just p-values that get hacked. We present evidence that the distribution of published Cronbach’s alpha values is also distorted in some way due to hacking and/or bias. @malte.the100.ci @ruben.the100.ci @taymalsalti.bsky.social osf.io/preprints/ps...

This year we host in October the META-REP 2024 an international conference focusing on meta-science and replicability in the cognitive, behavioral, and social sciences. The deadline for submissions is April 30. Contribute to vital discussions on meta-science and replicability. #metarep #openscience

Preprint updated because actually submitted - we discuss why differences in reliability might not actually inform you about differences in measuring quality - and what to do instead! Get the full story at osf.io/preprints/ps...

hello yes remember this? we have a new and improved version, check it out! osf.io/preprints/ps...

We love data from replication studies. Together with 146 researchers, we aggregated and coded replication findings. You can browse them in the @forrt.bsky.social #ReplicationDatabase: metaanalyses.shinyapps.io/replicationd... (1/3)

Probably late to the party, but MS Word changed the default font to something most of us never heard of before?

I'm searching for open replication data! Conceptual replications employing either: - same treatment/intervention but different outcome measure or: - different treatment (dose)/intervention but identical outcome measure (or both) Any pointers appreciated! #openscience #metasci

Sometimes, to distinguish a population parameter from an observed estimate, the term "true" is used. For example, sometimes researchers use "true mean" to distinguish the population mu (greek \mu) from the sample mean (x-bar). (1/3) #stats

When you discover new effects using preregistration, high power, & replicate faithfully with open materials, you get a replication rate of 86% & effect sizes 97% as big! Our new published paper with so many wonderful researchers: www.nature.com/articles/s41...

Here too for the X-boycotters: 1st 1st author manuscript, elated, etc. etc., let’s get to it: We need more high-quality norms in psychology and traditional sampling and norming techniques won’t get us there. MRP can help, though!

It's unbalanced advice. It places all expectations of civility on the commentor and none on the original authors or editors. Civility works both ways.
