“I once was blind”: experimental manipulation of religious attitudes via choice blindness Given ongoing debates about the nature and consequences of religious belief, effective procedures for experimentally controlling such beliefs are highly desirable. To date, however, there are few r...

Can people be led to defend the opposite of their religious beliefs? A new study by Prof. Ryan McKay and colleagues shows they can, shifting later attitudes too. The paradigm holds real promise for illuminating big questions in the field. Open access: doi.org/10.1080/2153...

It’s not that people doubt biodiversity is declining—it’s that we underestimate how many others already share this concern.

In our new Perspective, we review work on pluralistic ignorance and set out a research agenda to:

Also thank you very much, Robert (@robertboehm.bsky.social) for having me in your lab and for the discussions and mentorship. I’ll be back again with more interesting stuff!

I had an amazing time in Vienna☀️

Thank you Qinyu (@qinyuxiao.bsky.social) very much for hosting me!

It was great to host Hiro @hirotakaimada.bsky.social for a few days in Vienna to discuss research on in-group favouritism, indirect reciprocity, and intergenerational cooperation!

We found future ingroup favoritism and outgroup derogation in both minimal and national group contexts: people made more and less sustainable choices when future beneficiaries were ingroup and outgroup members, respectively.

When Confidence in Institutions Backfires: Power‐Distance Orientation Moderates the Relationship Between Institutional Trust and Civic Honesty Across Eight Countries Confidence in institutions is a key predictor of civic honesty, yet evidence shows that this relationship varies across contexts and individuals.

New paper orchestrated by @giotravaglino.bsky.social

Using data from 8 countries (🇬🇧🇺🇸🇮🇹🇰🇷🇯🇵🇩🇪🇨🇱🇨🇴), we found that the relationship between institutional confidence and civic honesty is moderated by power distance.

New work led and orchestrated by @sandrajgeiger.bsky.social🌍 We replicated pluralistic ignorance in climate beliefs in 11 underrepresented countries. Public-consensus intervention? Not really effective. We also looked at cultural differences using secondary data.

Had a great time visiting London Interdisciplinary School. I’m very excited for potential future collaborations🧠💡

Thanks to everybody who chimed in!

I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist.

So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>

Trait dissociation is associated with dissociative experiences arising from disrupted multisensory integration - Scientific Reports Scientific Reports - Trait dissociation is associated with dissociative experiences arising from disrupted multisensory integration

Really pleased that this paper from my PhD has been published in Nature Scientific Reports!

We used mixed reality to explore how manipulating multisensory integration leads to dis-ownership from the body and how those experiences relate to trait dissociation

We explored how individuals evaluate negative gossipers. We found that those high in social anxiety tend to like negative gossipers more than those low in social anxiety - suggesting that such gossipers may be seen as useful allies who help mitigate social anxiety

The evaluation of negative gossipers: testing the role of group membership and social anxiety While negative gossip serves important functions for groups, previous studies have revealed that individuals negatively evaluate negative gossipers. Given the ubiquity of gossip, there should be co...

We discused those results in relation to the previous literature on ingroup favouritism (i.e., social identity and group-bounded indirect reciprocity). For more detail, check this out🌞

Some players play for the Israeli national taem - do national team players change their cooperation depending on the number of national team players in outgroups? ...no, but we found that they cooperate more with ingroup members when their ingroup include more national team members.

Do players display an increased level of self-other overlap and cooperation with *former ingroup members (former team members) than outgroup members?
...self-other overlap was higher for former ingroups than outgroups, but players did not cooperate more with former ingroup members:

Do players show less cooperation toward outgroup members when they are set to compete against them the following day (high conflict salience: HCS).
...we did not find conflict salience influence cooperation:
