As a climate-focused psychologist, my paper introduces the "Capital-Climate Nexus" to examine how capitalism and climate change converge to shape the human experience. My new article came out before this one👇, but Albert (2025) offers a similar analysis. 7/n www.tandfonline.com/doi/full/10....

"Capitalism, despite being one of the most dominant and pervasive forces in contemporary society, remains remarkably invisible within mainstream psychological discourse," Bettache notes in the below video. A "Big Idea" to be overlooked in psychology, indeed. 🧵 5/n vimeo.com/1069464662

Simultaneously, Bettache (2025) was making the same argument beautifully in the journal Personality & Social Psychology Review. Importantly, he distinguishes between neoliberalism and capitalism. Whereas the former has made it into mainstream psych, the latter has not. 🧵4/n doi.org/10.1177/1088...

Research by Nisbet & Wilson suggest when people report on why they made a particular choice, they do not rely on true introspection, but refer to a priori, implicit causal theories or judgments about the plausibility that a particular stimulus caused it: buff.ly/1wUmUyV

PhD Isabel Pacheco and co-authors Ellen van der Werff and Linda Steg found that people rarely engage in #circular citizenship behaviours. How can we access all that untapped potential for #systemicchange through more citizen action in the future? Here's a thread on one of our recent papers🧵

Proud advisor moment. Check out my student, Emily Zohar's, new paper (her first first-authored paper) on how norms shape how effort. Yes, when we see hard workers around us, we work harder. But...when we see lazy people around us, we also work harder. Check it out! psycnet.apa.org/record/2027-...

You need one of GPT-5.2 Extended Thinking, Opus 4.6 Thinking, Gemini 3 Pro - yes you need to pay $20 Also, I hate to say it because it is very expensive, but GPT-5.2 Pro is the best for very hard high stakes problems.

What makes life most satisfying—prosperity, excitement, a coziness, or a sustainability? Research by Delhey et al using German panel data finds excitement and coziness are most important, with sustainability a distant 4th (negative for some groups): buff.ly/usYWmPL

A Heterogeneity Revolution in Psychology "When studies that may appear similar are repeated, findings often vary more than we would expect due to sampling error. This is not necessarily a problem if we understand why this happens."

New blog post, inspired by the excellent recent qualitative paper by Makel and colleagues: On the reliability and reproducibility of qualitative research. I reflect on how I will incorporate realist ontologies in my own qualitative research. daniellakens.blogspot.com/2026/02/on-r...

Is overconfidence a personality trait that applies across domains? The question divides the field of psychology, and an adversarial collaboration, while not settling the matter completely, let to agreement on a clear conclusion: buff.ly/Y4SvKC8

Note that this in itself is a well-replicated finding. At least a dozen studies show that when researchers replicate qualitative research, or re-analyze it, they come to basically identical themes. There is nothing special about qualitative research with respect to replicability.

“Positivism Creep” “The subtle, often unacknowledged infiltration of positivist or post-positivist assumptions into methodologies where they do not naturally, philosophically, practically, or epistemologically belong.” By @thomasgraves.bsky.social @maddipow.bsky.social @annayahprosser.bsky.social

Humility Revolution "Humility is not a threat to scientific authority; it is a strength. It shows disciplinary maturity, intellectual honesty, and methodological pluralism. A humility revolution must, surely, lead to better science." By @maddipow.bsky.social #PsycSci #MetaSci #Methodology

"I outline why modesty matters for science including the reform agenda, provide some practical steps that we can take to embrace modesty..." Ramsey (2021): psycnet.apa.org/record/2021-...

"Although intellectual humility is presented as a widely accepted scientific norm, we argue that current research practice does not incentivize intellectual humility." Hoekstra & Vazire (2021): www.nature.com/articles/s41...

New paper from Google on accelerating science using Gemini (as opposed to its specialized research AIs). Lots of case studies and interesting advice on ways to work with these system. "We view the AI as a tireless, knowledgeable, and creative bright junior collaborator." arxiv.org/pdf/2602.03837

Our new paper, with colleagues from the Strategic Council of the National Academies, offers an integrative framework of the several components that contribute to making research findings trustworthy including ethics, methodology, transparency, inclusion, assessment, etc www.pnas.org/doi/10.1073/...

Design can drive socially-desirable behaviour change, so our colleagues tested whether environmentally-focused packaging designs promoted recycling. They found that intention to #recycle, and actual recycling, increased with stronger #biospheric values. gep.psychopen.eu/index.php/ge...

every once in a while I read a paper that changes me. If you do research involving between-Ss experiments or interpreting between-people correlations in any way (e.g. SEM) read this paper, weep, & don't ignore the implications. from Michael D Hunter pmc.ncbi.nlm.nih.gov/articles/PMC... #psych

Professor Goda Perlaviciute explains how everyone has altruistic, biospheric, hedonic and egoistic values, and why all of them need to be taken into consideration when large-scale infrastructure, transport or sustainable energy projects are being planned.

People who engage in altruism that benefits themselves are derogated. Why? Social rewards are treated as being reserved for costly prosocial actions. Claiming such rewards without incurring costs seems like cheating and thus deserves moral derogation journals.sagepub.com/doi/full/10....

I like the word "mechanical" here. You can't discover novel info with a mechanical process. Reminds me of the factory metaphor for replications and the industrialization of science.

Our preprint has evolved! v2 of “Digital Behaviourism” is out now with a new title, new co-authors, and a deeper dive into the behavioural concepts that shape our online lives. It’s time to move beyond “screen time” and focus on function of online behaviours. osf.io/preprints/ps...

Why do I need to know this? Great blog by @nsachdeva.bsky.social and @jim-hewitt.bsky.social open.substack.com/pub/scienceo...

Super excited to see that somebody finally wrote about this 🥳 If you do research about research, you really need causal thinking (just like when you do research about anything else really).

People have so many epiphanies in the shower because it’s one of the few places without phones or other distractions. Imagine how many life-changing realizations you’d have if you were undistracted for more than 15 minutes a day…

The theory that underpins much of decision-making science falls short as a way to think about how we actually make decisions and how decisions should be made, argues Barry Schwartz in a new article. behavioralscientist.org/a-day-in-the...

When students offload cognitive effort to chatbots, their critical thinking ability suffers. But it is a rational response to results-based learning. Restricting or banning chatbots is the wrong reaction—competency-based learning is a better solution: buff.ly/QgQtK6V

Most people don’t benefit much from chatbots because what people lack is not good answers so much as good questions. It’s no longer enough to curate your feed; you must now also curate your curiosity.
