Is Joe Rogan really just a voice of the right? Our new @csmapnyu.org piece for @goodauth.bsky.social shows heโs just as much a space for the left and the center, too. A look inside todayโs surprisingly complicated podcast information ecosystem. ๐๏ธ

We are seeking a Fellow to lead cutting-edge research on short-form video content and its societal implications.
Bridging the gap between computer vision, causal inference, and computational social science, the Fellow will focus on the large-scale analysis of TikTok data (using an existing, massive dataset).
The position involves developing novel multimodal methods to understand how short-form algorithmic content shapes public opinion, political polarization, and online culture.
This is a unique opportunity to work at the forefront of the field, combining rigorous social science research designs with state-of-the-art computational techniques.
The Center for Information Technology Policy at Princeton invites applications for a Postdoctoral Fellow to work with an interdisciplinary team (me, @bstewart.bsky.social, and @manoelhortaribeiro.bsky.social).

Please apply by THIS SUNDAY, Dec. 14!

New in Science: Reranking partisan animosity in algorithmic social media feeds alters affective polarization www.science.org/doi/10.1126/...
Key from @jennyallen.bsky.social @jatucker.bsky.social: (1) important new paradigm (2) but not clear why results differ

Today, social media platforms hold the sole power to study the effects of feed-ranking algorithms. We developed a platform-independent method that reranks participantsโ feeds in real time and used this method to conduct a preregistered 10-day field experiment with 1256 participants on X during the 2024 US presidential campaign. Our experiment used a large language model to rerank posts that expressed antidemocratic attitudes and partisan animosity (AAPA). Decreasing or increasing AAPA exposure shifted out-party partisan animosity by more than 2 points on a 100-point feeling thermometer, with no detectable differences across party lines, providing causal evidence that exposure to AAPA content alters affective polarization. This work establishes a method to study feed algorithms without requiring platform cooperation, enabling independent evaluation of ranking interventions in naturalistic settings.
New paper in Science:
In a platform-independent field experiment, we show that reranking content expressing antidemocratic attitudes and partisan animosity in social media feeds alters affective polarization.

Examining news on 7 platforms:
1)Right-leaning platforms=lower quality news
2)Echo-platforms: Right-leaning news gets more engagement on right-leaning platforms, vice-versa for left-leaning
3)Low-quality news gets more engagement EVERYWHERE - even BlueSky!

Now in PNAS! With @mmosleh.bsky.social and @dgrand.bsky.social
Examining news engagement across 7 platforms, we find:
- differences WRT political lean ("echo platforms")
- similarities WRT news quality (posting low qual news => more engagement)
Read paper and thread for more!

Divergent patterns of engagement with partisan and low-quality news across seven social media platforms | PNAS
In recent years, social media has become increasingly fragmented, as platforms evolve
and new alternatives emerge. Yet most research studies a sing...
"While high-quality content is posted more and receives more total engagement across platforms...a given author attracts higher levels of engagement when they post lower-quality content"
"pattern we find seems to be driven more by an underperformance of particularly popular high-quality outlets"

2 โ Study behavior - not just belief
Many ppl see falsehoods, but who acts and when? Esp harmful acts like dangerous alt medicine or mob vandalism
3 โ Test interventions in fuzzy settings, not just black/white true/false content

This means 3 shifts for misinfo researchers:
1โDiscover misleading content from the bottom up. e.g. sample climate messages test which increase disbelief in climate change

Itโs time to reframe โthe misinfo problemโ: Instead of โWhy do people believe fake news?โ we need to study
- What leads to misperceptions
- How do they impact real-world behavior
- What interventions actually help reduce misperceptions

There IS a problem: Misperceptionsโeg election denialism, vax and climate skepticismโare common & impactful. But problem is less โPope Endorses Trumpโ style fake news, more stories like these ๐
Not false, but misleading โ and massively popular (see

People are worried re fake news, BUT studies show that outright false news is rare w limited impact. Critics say this means misinfo is a not a problem and we should stop studying it.
We disagree!

New in TiCS w @dgrand.bsky.social @gordpennycook.bsky.social
Itโs been ~10yrs since misinfo research exploded but our paradigms are stuck in the post-2016 โfake newsโ model
Time for new approaches:
o True/False โ Content that misleads
o Belief โ Behavior
o Eval interventions in ambiguous settings

New WP!
The illusory truth effect (repetition -> belief) is core to psych of beliefs, & thought to be a deep bias impacting misinfo, persuasion & advertising
Why would cognition include such a flaw? We argue it is a rational adaptation to high-quality info environments ๐งต1/
