🚨This preprint is now out in PNAS: www.pnas.org/doi/full/10.... We combine a dyadic foraging paradigm w/ computational modeling + ABM to study how people navigate differing preferences, share responsibility for shared outcomes & what that means for the group! more in 🧵⬇️ @fearbrain.bsky.social

🚨 Excited to end the year with a new preprint w/ Wenning Deng (not on bsky) and Dean Mobbs @fearbrain.bsky.social 🎉 🎉 "Blame and Compromise During Risky Dyadic Foraging" osf.io/preprints/ps... Feedback is very welcome! Thread: 🧵 1/n

Google DeepMind researchers have transformed classic psychological theories of attitude change into executable models using generative AI, simulating historical behavior patterns. This work clarifies theoretical ambiguities and highlights context's role. https://arxiv.org/abs/2604.19791

New preprint w/ @fearbrain.bsky.social, Bo Zhang, @aanixel.bsky.social & @pandascholar.bsky.social where we examine online political debates to understand how interactions become hostile using data from Reddit, real-time online chat experiments & brain imaging during chats - osf.io/preprints/ps... 🧵

I’m excited to share our new preprint: A Multi-Level Examination of How Hostility Unfolds During Online Argumentation. osf.io/preprints/ps... This is the first paper to examine how toxicity manifests from belief differences and how they are represented in the human brain.

✨New Perspective out w/ Wenning Deng and @fearbrain.bsky.social in @cp-iscience.bsky.social ! We argue that social foraging gives us a unifying, and ecologically grounded way to study how decisions unfold across levels — from individuals and dyads to collectives. www.cell.com/iscience/ful...

I wrote a thing on episodic memory and systems consolidation. I hope you all enjoy it and/or find it interesting. A neural state space for episodic memories www.sciencedirect.com/science/arti... #neuroskyence #psychscisky #cognition 🧪

A neural state space for episodic memories

Episodic memories are highly dynamic and change in nonlinear ways over time. This dynamism is not captured by existing systems consolidation theories …

🧵 How do we know Trump is full of sh** when he shrieks about “hydrants running dry”? Because in 2016, a horrendous wildfire hit Gatlinburg Tennessee. Hydrants ran dry and 14 people died. A higher death toll than the LA Fires. But Tennessee had a GOP governor, so newly-elected Trump posted:

I wish the government would understand that open access mandates are (on their own) invitations for profit-seeking publishers to gouge authors, universities, and funders by charging exorbitant fees. The government should directly support open access publishing, so that they can control costs.

More than 75 Nobel Prize winners have signed a letter urging senators not to confirm RFK Jr. The letter marks the first time in recent memory that Nobel laureates have banded together against a Cabinet choice. But Kennedy is a threat they could not ignore, one said. www.nytimes.com/2024/12/09/h...

First time this has happened.

I’ve personally experienced and seen anger at talks. Likewise, we have all experienced the angry reviewer. Both cases are unprofessional and unscientific. Yes, debate, but anger has no place in science (maybe one exception is pseudoscience or religion rejecting real science…).
