This recent blog post provides a very accurate and useful summary of Bertram and I's recent Nature Reviews Psychology article on the value of self-reports relative to "implicit measures" (as we defined them in the original article):

Self-report measures outperform implicit tools in assessing thoughts and feelings, new psychology paper argues
Self-reports outperform implicit measures, according to a new review, offering greater reliability, predictive validity, and flexibility. The paper challenges beliefs about implicit tools’ robustness,...

In a large, preregistered study (see preprint), we compared InteroMap to emBODY. Overall, InteroMap demonstrated superior construct validity and usability

Very excited to introduce InteroMap, a new bodily mapping tool designed to measure how we subjectively experience our bodily sensations, what we call interoceptive phenomenology 🧵👇

New publication. Congrats to the whole team, and especially @paulbertin.bsky.social who led this effort. Thanks also to the editor (Nicolas Sommet) and reviewers, who desserve credit for improving our paper.

We discuss whether this Truth Beliefs Conditioning effect should be considered an experimental demand artifact, and whether it matters.

This research follows-up on a recent article that examined three outstanding questions raised by instruction-based procedures:

doi.org/10.1525/coll...
Instruction-based Replication Studies Raise Challenging Questions for Psychological Science
A variety of psychological effects have been recently replicated in studies where participants merely received information describing experimental tasks, while participants experienced these tasks in ...

In this new research, we found that truth beliefs can be successfully conditioned:

Statements - true and false - are rated as more true after their pairing with positive than negative pictures.

This effect bridges research on evaluative conditioning and misinformation.

In this research, we found that individuating information dominates social group information when forming impressions about members of newly learned social groups. This dominance was observed both on self-reports *and* more automatic measures *despite* conditions favoring group-level impressions.

🚨 New paper alert, at @jexpsocpsych.bsky.social:

Classic person perception models argue that group information (e.g., group valence) dominates impression formation, especially in less-than-optimal conditions. But is this really the case?

This overturns familiar assumptions of perceivers as “cognitive misers” and calls for rethinking how we conceptualize automatic evaluations.

Even with skin tone as a group marker and explicit instructions to form group-based impressions, people relied more on the actual characteristics of the individual they encountered.

Olivier Corneille @ocorneille.bsky.social · 13d
I found the general discussion rather cautious, but this point might be further elaborated on. Another issue is that these manipulations are sometimes totally ineffective (Ps simply don't trust a hypothesis that runs against commonsense) but this does not seem to apply in this case 3/
Olivier Corneille @ocorneille.bsky.social · 13d
As a result, demand effects may operate differently in these studies vs. in original procedures where the experimental hypothesis is not directly communicated. The same issue applies when probing demand effects based on instruction-based replication procedures 2/
Olivier Corneille @ocorneille.bsky.social · 13d
If I may add a few thoughts, a major issue with this widespread approach to demand effects is that experimenters usually do not tell their Ps about their hypothesis. This communication creates unique demand characteristics that may consequentially depart from the original procedure 1/

Major new paper by finds implicit measures like the IAT are no better than asking people directly about their biases. After decades of avoiding self-reports, turns out our sophisticated replacement tools work no better than what we abandoned. New post!

It is amazing that most organizations (businesses, media, NGOs, political parties) that worried about the threat of the far right for decades have spent no time or energy to thinking how to operate in a far right world. They just continue to do the same and are surprised by a different outcome.

74% of Europeans say their country benefits from EU membership—the highest support recorded in 42 years.

With peace and security top of mind.

66% want a greater role for Europe in protecting them against global crisis & security risks.

We hear you. And we’re ready to deliver.
