In philosophy of perception, we find different intuitions pulling people in opposing directions

New studies from Eugen Fischer et al. show something important about that opposition:

It is not different people having different intuitions; it's each individual person having *conflicting intuitions*
Scientific or naïve? Perceptions of direct and indirect realism, and why they matter
Philosophical debates about the nature of perception are standardly informed by an empirical assumption about folk beliefs: They assume there is such a thing as “the” common-sense conception of visio...

my latest investigation for @consumerreports.org is based on months of reporting and 60+ lab tests of leading protein supplements

we found that most protein powders and shakes have more lead in one serving than our experts say is safe to have in a day (🧵)

CR tests of 23 popular protein powders and shakes found that most contain high levels of lead.

🚨New Preprint: We develop a novel task that probes counterfactual thinking without using counterfactual language, and that teases apart genuine counterfactual thinking from related forms of thinking. Using this task, we find that the ability for counterfactual thinking emerges around 5 years of age.

This is a big one! A 4-year writing project over many timezones, arguing for a reimagining of the influential "core knowledge" thesis.

Led by @daweibai.bsky.social, we argue that much of our innate knowledge of the world is not "conceptual" in nature, but rather wired into perceptual processing. 👇
Screenshot of a paper abstract:

“Core knowledge” refers to a set of cognitive systems that underwrite early representations of the physical and social world, appear universally across cultures, and likely result from our genetic endowment. Although this framework is canonically considered as a hypothesis about early emerging conception — how we think and reason about the world — here we present an alternative view: that many such representations are inherently perceptual in nature. This “core perception” view explains an intriguing (and otherwise mysterious) aspect of core-knowledge processes and representations: that they also operate in adults, where they display key empirical signatures of perceptual processing. We first illustrate this overlap using recent work on “core physics”, the domain of core knowledge concerned with physical objects, representing properties such as persistence through time, cohesion, solidity, and causal interactions. We review evidence that adult vision incorporates exactly these representations of core physics, while also displaying empirical signatures of genuinely perceptual mechanisms, such as rapid and automatic operation on the basis of specific sensory inputs, informational encapsulation, and interaction with other perceptual processes. We further argue that the same pattern holds for other areas of core knowledge, including geometrical, numerical, and social domains. In light of this evidence, we conclude that many infant results appealing to precocious reasoning abilities are better explained by sophisticated perceptual mechanisms shared by infants and adults. Our core-perception view elevates the status of perception in accounting for the origins of conceptual knowledge, and generates a range of ready-to-test hypotheses in developmental psychology, vision science, and more.

Our paper in annual review of dev psych is out! It's a big-picture look at the development of social cognition from a computational perspective: compdevlab.yale.edu/docs/2025/an...

When some kids say "any", they seem to mean no. Huh?

We show they really do, and why. The key idea: kids figure out what "any" means from the sentences it's in. But a concord negator in the same spots can look the same ("I don't want anything" vs. "I don't want nothing") doi.org/10.16995/glo...
When the syntactic bootstrap breaks: Some children think <em>any</em> means <em>no</em>
Children can use distributional information about where words occur to figure out their meanings. But what happens when two very different words not only have most of their distribution in common, but...

New publication forthcoming in BBS, co-authored with John Krakauer: a commentary on @smfleming.bsky.social & @matthiasmichel.bsky.social's groundbreaking target article.

We critique widespread assumptions in cognitive neuroscience about the role of internal models in implicit cognition. (1/7)

The following article is now in press at Psychological Review. Interested to hear what people think! "The successes and failures of Artificial Neural Networks (ANNs) highlight the importance of innate linguistic priors for human language acquisition".

Really excited to share my first ever published paper, forthcoming in Philosophical Psychology: "From Monkeys to Infants: The Empirical Challenges Facing Mental Fictionalism"

It's open-access, which I'm really happy about.

Brief 🧵 on what it's all about!

Really happy to have a new paper forthcoming at PPR!

Ever wondered if there’s any point in feeling regret? In this paper, I argue that regret is valuable because it helps us overcome temptation. Check it out: philpapers.org/rec/GOHRLA
