Seven minds wrote a paper on seven questions on mind perception. Why seven you ask? Well this is not a complete list, they merely reflect questions that we have been thinking and working on over the last couple of years. This was so fun writing with the team. A real collaborative piece!

Seeing a mind isn’t just about looks. From humans to robots, this study explores how we recognize thinking & feeling, why context matters, and why beliefs shape judgment.🧠 #OpenAccess doi.org/10.1163/1568... @fabioladiana.bsky.social @annhogenhuis.bsky.social @ruudhortensius.bsky.social
Mind perception across agents and species. Example of an interactive setup from our lab that tests mind perception across agents and species using a mobile neuroimaging setup. A human participant engages in an interaction with another human, AI chatbot, or a Border Collie dog (Canis familiaris). Photographs by Dorka Boda. All individuals gave permission for publication of the photographs.

A fun new preprint with the 🌟 team. We discuss 7 questions on mind perception we have been thinking and working on in the last years and it also features a picture of a dog! I mean what's more to like?

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.
Experimentology cover: title and curves for distributions.

So normally I go to gigs at TivoliVredenburg, but yesterday I was standing on stage at the sold out Social Animal event at TivoliVredenburg organised by KLI and ASPO. I really felt like a rockstar. 🤟🤟🤟 Great evening with super cool talks and people. If you can, do visit it next year!

Now that Bitcoin ETFs have been approved, let's recap the colossal waste of resources in BTC mining over the past year. During 2023, Bitcoin's proof-of-useless-work mechanism consumed almost as much electricity as the entire traditional financial sector combined.

While I don't like the loser/winner dichotomy, this comic made me laugh
Comic showing a winner posing as a winner first, but slowly transforming into a superloser, saying: "people think there are winners and losers, but the winners also lose. They lose more than the losers. They're secretly just superlosers. don't be a loser, be a superloser"

The "I only worked 35hrs a week as grad student & am successful, so you should do it too" rationale mistakes work hours for the *one* main factor of academic success: Ability, luck, mentors, resources, family support & many other factors play crucial roles.

This tweet by Alessandro Nai is one of the real life examples of deviating from a preregistration that I use in my new preprint. osf.io/preprints/ps... Mistakes in a preregistration happen! If they are obvious enough, peers should agree they do not impact the test severity.

Does the use of a state-of-the-art LLM change how we judge the capabilities of artificial intelligence (AI) to evaluate the morality and competence of someone? Find out in our new preprint: osf.io/preprints/ps...
Interaction plots of the perceived plausibility of AI origin by Dimension and Pole of the behavior behind an impression description across three experiments. Result show that people tended to attribute competence-related impressions to AI rather than morality-related ones, particularly for behaviors scoring high on morality or competence.
