We outline our key points in a series of bite-size tables. E.g.,

For democracy to be truly representative we need to include many more voices. But young voters (18-25yo) face unique barriers and are often overlooked.

We describe these barriers, and propose a psychologically-informed approach to support and increase voter turnout among youth.

Interesting! Although it actually looks like the proportion of political tweets that a user posts—not their *potential exposure* to toxic tweets by accounts they follow—is the strongest consistent predictor of a user's likelihood of posting BOTH impolite or intolerant tweets.

🚨Excited to announce the full-day Moral Psychology pre-conference at #SPSP2026!

We sold out last year, and with this year’s incredible speaker lineup, we expect the same.

Submit your poster or data blitz abstract by Oct. 23! spsp.wufoo.com/forms/2026-p... There’s a best poster award!

🚨Excited to see our new paper out in @pnas.org led by @asinclair.bsky.social!🚨

We tested 17 psychological interventions head-to-head in a “tournament” to see what motivated people to take action and share info about climate change.

Winners depicted here for brevity; read our paper for details!

Interesting! Where did Meta announce this? Is it from this blog post re: this section here? ai.meta.com/blog/llama-4...

Moral Psych community: @jowylie.bsky.social & I will be organizing the pre-con at SPSP again! This past year was sold-out and we expect next year to be even bigger!

Who do you YOU want to hear from next year? Recommend a speaker with this quick form: tinyurl.com/moralpsychrecs

Plus nice commentary by Dean Knox & Jonathan Mummolo emphasizing that since actual speeding was rare (3.4% of data), racial disparity is even larger. I.e., denominator should be conditional on speeding

Using GPS data from 220,000+ Lyft drivers in Florida to look at actual speeding behavior (not just police reports), Aggarwal et al find:

White & Minority drivers drive similarly, BUT minority drivers were 33% more likely to be cited for speeding + paid 34% more money in fines.

New research finds that people form swirling ‘vortex’ patterns in densely-packed crowds, with individuals moving in circles. Collective oscillations in massive human crowds! www.nature.com/articles/s41...

Interesting paper finds that Republican elected officials are not fact-checked more often than Democratic officials. Politician prominence predicts fact-checking, but partisanship does not. t.co/K0F6oJ3V1m

In the end, most people understand that most scientists try to get things right. About 76% of Americans trust scientists today even after the pandemic dip, and people around the world overwhelmingly want scientists to share their work and be involved in policy-making

But we also shouldn't just write off economists, left or right, as "totally politically biased".

Instead, we should examine the evidence and debate any model assumptions that drive differing elasticity estimates (e), which in turn drives differing optimal top tax rates.

Excited to announce the return of the Moral Psychology pre-conference at #SPSP2025! A crowd-pleaser for over 20 years!

We have an incredible lineup of speakers! 🚨Deadline to submit an abstract is tomorrow night (Oct. 17, 11:59pm PT).🚨 Submit here: bit.ly/3NsJiaQ

UPenn's MindCORE Postdoctoral Fellowship is accepting applications (due Dec 3)! t.co/hX34aZHAQy

Funding is available for 3 years. Fellows receive $68k in salary, $20k in a research/travel budget, assistance in relocation (e.g., $5k), and benefits.

Highly recommend it!

Excited to be sharing some research at SESP in Madison WI this afternoon 4:50-6pm in the Senate Room! It's a great lineup with Karina Schumann, Erik Santoro, and Leaf Van Boven so don't miss it!

AI can suggest rephrasing of messages during cross-partisan online conversations that improve reported conversation quality, promote democratic reciprocity, and improve the tone, without shifting people's policy positions www.pnas.org/doi/10.1073/...

Partisan incivility on social media (Reddit) is more driven by toxic people being toxic and opting in to partisan discussions (the troll hypothesis) -- less from actual disagreement about political issues or from status competition between groups academic.oup.com/pnasnexus/ad...

Groups can "fail" to reach a decision if some minimum number of votes is not met (e.g., hung juries). Often a pivotal jury member can decide whether to "tip" the group into making a decision. And they appear to do so, often in the direction of punishment. www.pnas.org/doi/abs/10.1...
