12 years separate these two pictures, and in the meantime we moved from Maître de Conférences (assistant professor) to Professor. The big difference? We lost the French style! ^^

...and this globally fits with the non-effect of choice we got from the dissonance RRR (2024)

More preregistered cognitive dissonance without choice findings! Choosing for people makes them rationalize they like the task more. From @kurtmunz.bsky.social papers.ssrn.com/sol3/Deliver... #psych

A (serious) game to guess if a study has been replicated based on the abstract! (and IF). lukasroeseler.github.io/GuessTheRepl... Amazing but very hard! Nice job @aufdroeseler.bsky.social! This is fun and useful. Best conclusion so far: you cannot trust anything based on the abstract! :)

I'm not a big fan of rituals, but I truly wish us all a better world! Let's remember that people are not their governments. Several of the latter must be stopped now, while many of the former must be supported and empowered to change the game.

happy new year 2006 (crossed)

What is the current position of @improvingpsych.org concerning the Washington meeting after the last Trump's administration proposal? Requiring 5 years of social media history, phone numbers, and email addresses is invasive and concerning for anyone who values privacy and freedom of thought.

Moreover, self-persuasion as well as self-perception do not rely on discomfort. Anyway, it makes me a feeling of déjà-vu and I believe we already had this discussion before! :) My main conclusion with the RRR is that the paradigm is flaw, but I cannot discard the whole theory with this results.

010

David C. Vaidis @vaidis.bsky.social · 08/11/2025

Yes but they were all informed about this tuition raise so they should all experienced such discomfort thus? But we observed the discomfort and conflict in the inconsistency behavior conditions with all ds > .66 and they all answered the same item about attitude. Not perfect, but not discarding.

David C. Vaidis @vaidis.bsky.social · 08/11/2025

It does make sense to consider that changing the others is a way to make the social reality consistent with your thoughts but the current experimental or observational evidence are scarce.

000

David C. Vaidis @vaidis.bsky.social · 08/11/2025

Only a few models, like the EIM could explain proselytism. More generally, the most common reactions to disconfirmation are maintain or change (or assimilation/accommodation, or exploitation/exploration; depending on your theoretical background), not proselytism.

100

David C. Vaidis @vaidis.bsky.social · 08/11/2025

I really did not want to write on this but as many people talk about it, I think it is necessary to restate some basic elements. The proselytism has never been a strong assumption (this is even sometime hard to explain why it should occurs).

110

David C. Vaidis @vaidis.bsky.social · 08/11/2025

You should read Chapanis & Chapanis (1964)! They had almost the same conclusions more than 60 years ago! So nothing new here. But things move forward in the meantime.

010

David C. Vaidis @vaidis.bsky.social · 08/11/2025

So hard critic is okay to move forward but Science is much more. a/ Read the papers (not just abstracts) b/ Put them in perspective with the full literature Critique the ethics AND maintain scientific rigor. #replication #cognitivedissonance #scienticrigor

061

David C. Vaidis @vaidis.bsky.social · 08/11/2025

Bottom line: Yes, condemn the unethical methods. But don't dismiss cognitive dissonance theory based on one inconsistent secondary effect. We must be serious in engaging in Science.

150

David C. Vaidis @vaidis.bsky.social · 08/11/2025

The proselytism effect was never robust. Hardyck & Braden (1962)—just 6 years later!—found disconfirmation and maintenance of the belief but NO proselytism. Batson (1975) confirmed: not everyone becomes a proselyte after disconfirmation. #replication

140

David C. Vaidis @vaidis.bsky.social · 08/11/2025

Kelly (2025) emphasizes two points: a) unethical research methods and b) lack of proselytism effects. I completely agree the ethics were problematic—this has plagued social psychology for decades (see: Belmont Report, Milgram, Zimbardo). #ResearchEthics #PsychologyResearch

130

David C. Vaidis @vaidis.bsky.social · 08/11/2025

I didn't want to get into this discussion, but after seeing strong reactions to Kelly (2025), I think it's worth helping colleagues think more critically about what the paper actually shows—and doesn't show. Spoiler: not the bombshell some claim. #SocialPsychology #CognitiveDissonance

Debunking “When Prophecy Fails”

In 1954, Dorothy Martin predicted an apocalyptic flood and promised her followers rescue by flying saucers. When neither arrived, she recanted, her group dissolved, and efforts to proselytize ceased.....

Was looking into what Cognitive Scientists mean by ‘domain-general’ cognition, and then hit upon this. This is definitely NOT how we use that term. Tip: read the last sentence to understand what went wrong here. Sigh.

Domain-General Cognitive Ability
In subject area: Psychology
Domain-general cognitive abilities refer to cognitive skills that are not unique to humans but are present across various primate species and potentially other mammals and birds, indicating a general factor underlying cognitive performance that correlates with brain size and is associated with selective attention and working memory capacity.
