Need to backup your Qualtrics?
I needed this urgently given a revocation of my Qualtrics account with my former affiliation.
Found William Ryan's R code, but it didn't work for me, so I made some tweaks, and it works now.
Hope it's helpful to others:

Too often, I see people talk about a replication as if the first study has established something, and the replication study is a double-check. What people often fail to understand is that we do not do replication studies to *check* a finding, but to *establish* a finding. 1/x

Leveraging London's streets as one of its most valuable assets, Strand Aldwych transforms one of Westminster's busiest and most polluted corridors into a vibrant and verdant destination. By filtering out through traffic, 7000 m² of roadway is reclaimed into an accessible and welcoming public space.🧵

Expressing intentions is not climate action letter published in PNAS: https://www.pnas.org/doi/10.1073/pnas.2512457122
In our now published letter in @pnas.org, we raise two wider issues for behavioral science:
1) Intentions are poor predictors of behavior
2) Effects on intentions need not generalize to effects on behavior
We join calls for researchers to measure actual behavior: www.pnas.org/doi/10.1073/...

Truth is that over 90% of nations in the Paris Agreement can make that same claim. We are not special. All countries must play an ambitious role, & no time to lose

(5/5)
Before participants learned their rank, the Injunctive Distribution Task (IDT) asked how much top global earners should donate annually. While the IDT didn’t significantly raise donations, follow-ups will explore whether this is due to the gap between annual income (IDT) and windfalls (DV).
(4/5)
Exploratory analysis further showed that after exposure to their rank, participants were more accurate in predicting the global distribution of income, relative to those who were not.
(3/5)
People in high-income countries underestimate their rank position relative to others globally – therefore communication of one’s rank position relative to others (Rank-Based Nudge, RBN) led to an increase of the windfall bonus (from a raffle) donated to Against Malaria Foundation (AMF).
(2/5)
New preprint w/ @glenspiteri.bsky.social , @maxmaier.bsky.social & Falk Lieder: Telling people their global income rank (RBN) increased charitable donations. Also explored RBN’s effect on perceived global income distribution + whether asking how much others should donate increased giving (IDT)
