In a new @Nature paper, #BCFGTeamScientists David Yeager, @chrisjb1, James Gross, and colleagues demonstrate that a short, low-cost mindset intervention buffers the negative effects of stress among adolescents.

@CamHostinar @CamHostinar, Study 4 in the paper is a pre-registered replication of the cardiovascular outcomes

A 30-minute self-administered intervention that combines growth mindset and stress-is-enhancing mindset intervention seems to show benefits for reducing stress in adolescents and college undergrads. Wish cardiovascular and cortisol analyses had been pre-registered, but promising.

How can you help your stressed teen cope? A @nature paper presents a new, 30 min intervention that reduces perceived and physiological stress in multiple groups of highschool and undergraduate students nature.com/articles/s4158…

I can’t count the number of times @davenuss79 has helped me come up with just the right framing for a media pitch about one of my papers or op-Ed ideas. He has contacts at top media outlets and an insider’s feel for how to get them interested in academics’ ideas.

I'm incredibly thrilled to announce that today @psychgeistmedia is officially open to the public! We've been working toward this for a long time and we're incredibly grateful to everyone who has helped us along the way. Come see: psychgeistmedia.org twitter.com/PsychgeistMedi…

This is what lunch prep looks like with 5 kids. Ugh, I really need to get more reusable containers.

@mddidomenico @DataColada @USGSA But, I asked a friend who was involved in the work and he confirmed that @mddidomenico is correct. The tests were signature at the top vs. no signature. Bottom line: I think more tests are needed before we have clarity on the effectiveness of this nudge.
English
@chrisjb1 @DataColada @USGSA Important to note that the OES study is not a test of signing up front versus at the end but adds a signature at the top when there was none in the control--which is properly called out in the PNAS replication paper.
English
The revelation on @DataColada about fraud in the Shu et al paper seems incontrovertible but it’s worth noting that there is one legitimate demonstration of the effectiveness of the sign-at-the-beginning nudge from @USGSA’s OES: oes.gsa.gov/projects/iff-r… (1/2)
English
@mddidomenico @DataColada @USGSA Quick update. I was trying to figure out why I had the impression that the OES tests used the same top-vs-bottom signature manipulation as the original paper. Turns out they described it that way in the published summary of findings (see: psychologicalscience.org/policy/the-us-…).

You, too, could find yourself in gauzy beauty shots of the CASBS campus that also vaguely convey stimulating intellectual interaction...

This is one example of why it’s critical that we begin to take heterogeneity more seriously in our research as @stats_tipton, David Yeager, and I argue here: @https://rdcu.be/cpu1A
English
They later tried to replicate the finding in a subsequent year and found more equivocal evidence: oes.gsa.gov/projects/iff-c… . To me, this suggests the effect may be real but heterogeneous.

Let's move beyond the replicability crisis
NEW PAPER: In @NatureHumBehav, fmr CASBS fellows @chrisjb1(2018-19) & David Yeager (2014-15) & Beth Tipton propose steps for a shared research infrastructure for studying behavioral interventions in heterogeneous & generalizable samples

Behavioural science is unlikely to change the world without a heterogeneity revolution. That revolution is coming, @stats_tipton, David Yeager, and I argue in a new paper out today in @NatureHumBehav. Check out the paper here: rdcu.be/cpu1A

This paper fueled a TON of conversation in July & (thoughtful) arguments over it are still going strong! Want to weigh in? The paper in question is now published HERE: pnas.org/content/116/51… @PNASNews @chrisjb1 #replication
CASBS@CASBSStanford
How big a problem is replicator degrees of freedom? CASBS fellows Chris Bryan & David Yeager show that common #replication practices allow authors to publish attention-grabbing “failed replications” even when they actually DID replicate the finding PAPER: bit.ly/2XBaFHZ

@BrianNosek Wanted to express my gratitude to @BrianNosek for sharing his take on our paper and thank all others who have offered constructive comments.

The vote outcome is pretty close to my prediction of the probability that this effect will replicate following the original authors clear methodological criteria (23% chance). 1/

The theoretical analysis is plausible, and the effort on reanalysis is substantial. Look at the paper, then consider: If a replication with new data is conducted meeting the authors' clearly specified methodological criteria, do you think it will replicate the finding? Why?
