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):

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 🧵👇

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.

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.
November 14, 2025 at 4:40 PM
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?

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!

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇

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.

We also recruited “observers” who were matched with the original “actor” participants, shown their choices, and asked to predict the actors’ choice process. Actors were more accurate than observers, suggesting that their accuracy came from some kind of first-person introspection.

Honest people don’t lie. Or do they? Liars aren’t honest. Or are they?
One puzzling conundrum in contemporary politics is that politicians who seem to be estranged from facts and evidence are nonetheless considered honest by their followers.
