We can't wait to learn from our keynote speakers at the PHAIR Animal Advocacy Conference 2025 📣 #animaladvocacy

Welcome to the Society for the Psychology of Human Animal Intergroup Relations (PHAIR) BlueSky page! 💙 Here we aim to advance and promote scientific research on moral and social psychology, diet and health, human-animal relationships, sustainability and environmental psychology. 🌱 phairsociety.org

It happened again, I revamped my website: www.willemsleegers.com

Check out the commentaries to our paper, as well as our response! For those interested in cognitive dissonance, I think these make for an interesting read.

What is the status of Nisbett & Wilson's (1978) Telling More Than We Can Know paper? Are there any good replications/reviews? (I couldn't find any quickly).

🐶Now out in PHAIR 🐶 Does generalized prejudice extend across species lines? I used data from the LISS panel & the European Values Study to test if people who devalue human outgroups also tend to devalue the welfare and interests of non-human animals. doi.org/10.5964/phai...

I feel like social media has failed me. Somehow I didn't hear about this failure to replicate the induced compliance paradigm for cognitive dissonance: journals.sagepub.com/doi/full/10.... - would love to hear what people closer to this research make of the finding.

Very pleased to see this project led by @vaidis.bsky.social and @willemsleegers.bsky.social published! If you have any interest in the replicability (or lack thereof) of a classic cognitive dissonance paradigm you'll want to read the paper 👇

It's finally out! Our large-scaled replication attempt of the induced compliance paradigm in the study of cognitive dissonance: journals.sagepub.com/doi/10.1177/...

Now out at EJP w/ @willemsleegers.bsky.social, @juliastern.bsky.social, @larspenke.bsky.social, @alexjonesphd.bsky.social doi.org/10.1177/0890... We tested how accurate people are at judging others' personality based on a facial photograph & whether they are aware of their own (in)accuracy. A🧵

Time to be more active on social media, starting with a tidystats update. I've been working on a big update, both to the R package and the Word add-in. I just submitted the update to Microsoft, so hopefully it will be available soon!

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...

What are the benefits and challenges of collaborations between psychological scientists and advocates? Read the interview with Chris Hopwood, Editor-in-chief of the PHAIR Journal, about the history and purpose of the ‘roadmap for collaboration’ @chopwood.bsky.social phairsociety.org/2023/10/20/a...

Hi everybody. Is this where all the psych science people are at?
