@louisareins.bsky.social and I started this project shortly before my nephew was born - he will start school soon. The drinks were consumed during the revisions. Link to paper (let me know if you don't have access), summary and preprint below. With S. Orr, M. Mizumoto, A. Erut & Q. Li.

Moreover, lie and falsity attributions correlated strongly in our between-subjects design. In a follow-up experiment (in only three countries), we found this strong correlation also with a within-subject design design. Preprint: osf.io/preprints/ps...

In one condition, we asked whether the speaker lied, in another whether what s/he said was true or false. Although DIs can be considered borderline cases (true on the explicit level, false on the implicit level), we found a high degree of similarity between the ten countries.

In our main experiment, we presented participants from ten countries (Chile, China, Germany, Israel, Japan, Mexico, South Africa, Spain, UK, US) with ten cases of deceptive implicatures (DIs). DIs are literally true but can nevertheless trick the hearer into a false belief.

Randomly discovered that I have a signed book by Daniel Dennett 🤯 (the book was left, among others, in the office of a former colleague)
Signed book page by Daniel Dennett. Title of the book: breaking the spell.

Lay people clearly think you can lie with pictures in form of a Content lie and a Target lie, and also tend to agree that deceiving in form of 3. constitutes lying.

Preprint: osf.io/preprints/os... Experimental setting: Two persons communicate via a messenger. A wants to buy a used bike from B and asks whether it is scratch-free. The bike has a scratch. B replies with a picture of the bike.

🚨paper alert🚨 with Emanuel Viebahn Can you lie with pictures? Some (says-based) theories deny this possibility but lay people clearly think you can lie with pictures – and in at least three different ways. Forthcoming in AJP. Short thread with link to paper below.

Happy to announce a new volume in the Bloomsbury series “Advances in Experimental Philosophy”: Lying. It will mainly about (experimental work on) the concept of lying, but also about related concepts and non-conceptual issues. Hopefully out 2024. Table of contents below.

Finally, participants were quite confident in their lie and truth evaluations, and moral evaluations of the cases were also similar between countries. Preprint: osf.io/preprints/ps...

Alex Wiegmann @alexwiegmann.bsky.social · 03/04/2024
Perhaps surprisingly, lie attributions (r=.93) as well as falsity attributions (r=.91) were quite similar between the ten countries.

Alex Wiegmann @alexwiegmann.bsky.social · 03/04/2024
As in previous studies, different cases of deceptive implicatures received different lie and truth evaluations. Overall lie attribution was 57%, overall falsity attribution 49%, and lie and falsity attributions correlated strongly (r=.94).

Alex Wiegmann @alexwiegmann.bsky.social · 03/04/2024
We employed cases of deceptive implicatures (DI), i.e. speaker said something literally true but implicitly communicated something false, and asked participants whether the speaker lied and whether what she said was false (between-subjects).

In Exp 2 we additionally asked participants to guess how other participants (either R or D) would judge the respective cases. It was found that partisans massively overestimate bias in political opponents (and, to a lesser agree, also in members of their own camp). (4/5)

Alex Wiegmann @alexwiegmann.bsky.social · 21/12/2023
We found that republican and democrat participants exhibit only a small bias: lie ratings for members of the same party were only slightly lower. Surprisingly, there was no big difference in the degree of bias between clear lies and deceptive implicatures. (3/5)

Alex Wiegmann @alexwiegmann.bsky.social · 21/12/2023
In Experiment 1 we presented Democrats (D) and Republicans (R) with short stories in which a politician makes a deceiving statement. We manipulated the political party of the speaker (D vs R) and whether the speaker deceived by a clear lie or by a deceptive implicature. (2/5)

New paper (Social Psychological & Personality Science) by @louisareins.bsky.social (did all the heavy lifting) and I on partisan bias in lie judgments. Upshot: Democrats and Republicans exhibit only a small bias but think the other side is massively biased. Short thread and link below. (1/5)
