Not unexpected, but still shocking…

Overall, our results differentiate norm inference from norm adoption and highlight behavioral prevalence as a stable normative driver. They also raise concerns about how visible peer behaviors may facilitate the diffusion of risky disclosure practices.

(9/end)

Reinforcement signals (likes and comments) showed no observable effect on norm formation or disclosure intentions. This challenges common assumptions about the centrality of engagement metrics in shaping behavior.

(8/9)

Similarity moderated these processes. Participants relied less on prevalence cues when evaluating similar others, yet similarity amplified the impact of norms once they were formed.

(7/9)

Written disclosure had a more limited role. It shifted norm perceptions modestly but did not meaningfully influence disclosure intentions, suggesting a modality-specific sensitivity to normative information.

(6/9)

The findings were quite consistent: prevalence was the dominant mechanism. Higher levels of visual disclosure among peers led to stronger descriptive and injunctive norms, which in turn increased participants’ own disclosure intentions.

(5/9)

We therefore developed a new platform called Travelgram, closely resembling Instagram. It simulated the full social media experience. Participants scrolled, posted, liked, commented and we manipulated what they saw.

(4/9)

Across two preregistered experiments (n=590; n=1337) using a ecologically valid, but simulated platform, we independently manipulated two elements: the prevalence of others’ disclosures and reinforcement via likes/comments. We further measured perceived similarity of other users.

(3/9)

Building on my previous work (doi.org/10.1371/jour...), we argue that platforms are saturated with signals about what others do, and these signals structure users' own decisions to share.

NEW PREPRINT 💡

Together with @dougaparry.bsky.social, I just published a new preprint experimentally examining how specific normative cues on social media shape self-disclosure using an innovative simulation approach.

New paper on algorithmic gatekeeping & news engagement out at JOC!

Lucien Heitz, @masurphil.bsky.social, @judith-moeller.bsky.social, @vanatteveldt.com & me ran a 1-week long field experiment to test if we can nudge people to read (and learn from) environmental news.

Oh, this is old. I think I should revisit this. :D

Thanks, Cameron!

Thanks so much, Ye!

Using specification curve analyses, we show that this relationship is sensitive to analytical decisions, highlighting the importance of transparency and replication in survey-based privacy research.

(4/4)

Only 32.5% of the original effects replicated exactly, though 67.5% were significant and in the expected direction. Interestingly, the widely reported negative link between privacy concerns and self-disclosure did not replicate—in our data, it turned positive.

Together with Giulia Ranzini, we closely replicated three foundational studies in privacy research:
🔹 Krasnova et al. (2010) on the privacy calculus
🔹 Vitak (2012) on context collapse
🔹 Dienlin & Trepte (2015) on the privacy paradox

Hello world! Meet our consortium—15 organizations, 10 countries—joining forces to rethink the digital political information space. 🚀

Last week, we kicked off our project WHAT-IF, setting the stage to build a digital twin that will help us test the impact of policy interventions.

More in the 🧵!
