Proud of this paper; five years in the making. Correcting consumer beliefs about carbon impact of meat products (controlling for salience and social norms) does *not* lead to any change in consumption behavior in our setting. Any effects of carbon labels are likely to work through salience/norms.
Colleagues and I happy for any feedback. 🧪 #HBES

The joint @ces2026.bsky.social / #HBES2026 is a wrap. Local organizers @zhgarfield.com, @edseabright.bsky.social, @sarahalami.bsky.social, & @matcharbonneau.bsky.social & their amazing support team pulled off TWO back-to-back conferences. The vibe, food, high-tech venue & talks were fantastic!
Looking forward to be in Toulouse next week, talking about "The cultural ecology of social media", and meeting people at IAST. Thank you for inviting me!
