📊 New resource: ISAAC, an open corpus for studying social group attitudes 💬 527M+ Reddit posts (2007–2023) 🧠 Covers race, sexuality, age, ability, and skin tone 🗺️ Validated against Gallup and Google Trends 🔍 No-code or Python/SQL: isaac.psychology.illinois.edu 📖 Preprint: arxiv.org/abs/2609.27059
We introduce the Illinois Social Attitudes Aggregate Corpus (ISAAC), an open, modular, and accessible corpus of 527 million+ English-language Reddit posts selected for relevance to six key social group distinctions based on race, sexuality, age, ability, body weight, and skin tone, covering the 17-year period from 2007 to 2023. A multi-step, human-audited filtering pipeline was used to keep irrelevant content in the curated dataset below 10%, both overall and for each social group distinction. Each post was then algorithmically annotated with the user's estimated home region, along with a suite of validated off-the-shelf and custom semantic labels including moralization, sentiment, emotion, and linguistic generalization. We confirm the validity of the resulting corpus through convergent evidence linking ISAAC to macro-level societal trends, such as online search behavior, temporal spikes during major societal events (both nationally and regionally), and long-term shifts in public attitudes. By offering a unified, public infrastructure, ISAAC eliminates research fragmentation and enables seamless replication while supporting diverse empirical workflows at scale. Specifically, ISAAC allows investigators to perform cross-category comparisons, conduct high-precision tracking of long-term temporal shifts in social group discourse, and map spatial variation onto localized public opinion and policy outcomes. ISAAC's fully public, modular pipeline facilitates easy extension of the corpus to new platforms, languages, and social categories. To accommodate various research needs, ISAAC is accessible both without coding through a point-and-click website and labeler web-apps, and programmatically via an SQL playground, a Python package, and HuggingFace.

Project Implicit Continues its Critical Work
We are more excited than ever to not only continue but to expand the scientific collabora-tion at the heart of Project Implicit. With the non-profit that served as our operational home for two decades shutting down, a new organizational structure is being finalized to carry our research and educational mission forward.
In the meantime, the Project Implicit website (http://implicit.harvard.edu/) remains fully operational and continues to collect data 24/7. New studies, programs, and educational ef-forts are actively underway. We expect public data to remain available in perpetuity, and new data from 2026 will be released in January of next year.
We express our deep gratitude to everyone who has helped create, sustain, and grow Pro-ject Implicit. This includes the founders, members of the Board of Directors and the Scien-tific Advisory Board, staff members of the non-profit, international collaborators, and the students across dozens of labs tending to tasks big and small. We are also thankful to our generous donors who have answered our calls and supported our mission, and especially the millions of annual visitors who continue to honor us with their curiosity, time, and data.
We look forward to providing more details in the weeks ahead.

New paper out now 🥳 When psychologists discuss generalisability, they often refer to vague notions of representativeness. We provide an accessible intro to the total survey error framework as a tool to reason about this more rigorously. w @taymalsalti.bsky.social @ruben.the100.ci >
Thinking Clearly About Sampling and Representation With the Total Survey Error Framework

Collecting a sample that represents the population of interest well constitutes a challenge across the social and behavioural sciences. Psychology in particular frequently relies on convenience samples—most notably students and, increasingly, online participants—with a tendency to either (implicitly) assume representativeness without substantive justification, or to acknowledge a lack of it only in passing. In contrast, researchers rarely engage with the actual implications for their inferences, which undermines the generalisability of psychological findings. Critically, representativeness must be defined with respect to variables relevant to the target of inference, rather than superficial demographic diversity. Here we present the Total Survey Error (TSE) framework as a methodological tool that systematically addresses the multifaceted sources of error—particularly those related to representation—that emerge throughout the research cycle. Although TSE originated in survey research, its principles are broadly applicable to any psychological study seeking inference from sample to population. We offer practical strategies for identifying, preventing, and mitigating representation errors to improve the credibility and generalisability of psychological research.

Illustration of the total survey error framework with the representation strand highlighted. It shows how coverage error, sampling error and non-response error arise during the sampling process.

Are the mental contents underlying implicit evaluations accessible to conscious introspection? Prior studies show high predictive accuracy, leading to a growing consensus that people can introspectively access their implicit biases. New paper out in JPSP! 🧵🧵🧵
The tide is turning against a major idea in social psychology: that implicit evaluations reflect mental content that lies beyond conscious awareness. This view is being reconsidered in light of mounting evidence that people can predict their own implicit evaluations with high accuracy. However, there are reasons to question whether such predictive accuracy reflects introspective access. First, prior studies have relied almost exclusively on familiar targets (e.g., racial groups), allowing predictions to be informed by background knowledge (e.g., knowing that a group is stigmatized) rather than introspection. Second, implicit and explicit evaluations have been highly correlated in prior work, enabling accurate predictions simply by assuming that implicit evaluations mirror explicit ones. Here, we report eight experiments (five pre-registered; N = 6,794) designed to minimize these nonintrospective routes to predictive accuracy. We introduced participants to novel targets and shifted implicit and explicit evaluations of these targets in opposite directions, rendering explicit evaluations an unreliable cue. Under these conditions, predictive accuracy ranged from low to nonexistent; participants frequently anticipated shifts in their implicit evaluations in the opposite direction of the actual change. These results generalized across two learning paradigms (impression formation and attribute conditioning), two implicit evaluation measures (Implicit Association Test and evaluative priming task), and between-participant and within-participant designs. We consider multiple interpretations of these findings, including the possibility that implicit evaluations reflect mental content that is largely or even entirely inaccessible to conscious awareness.

findanexpert.unimelb.edu.au
Realigning interpersonal regulation in everyday life : Find an Expert : The University of Melbourne
<p> Our societies are becoming more socially disconnected. To address this problem, we need to understand how social connection is created. One powerful method to build social connections is interpersonal emotion regulation, which involves the processes through which people seek and offer emotional support. However, people report providing more emotional support than they receive, suggesting that the provision of emotional support is often unnoticed or unsuccessful. This project aims to understand and reduce this misalignment between the perception and provision of emotional support in everyday life. To do this, we investigate these processes in romantic couples, using new dyadic experience-sampling tools to capture both partners’ perspectives in real time. The project consists of three work packages. Work Package 1 will determine whether perception-provision misalignment is most frequently driven by the receiver or the provider, and which type of misalignment is more consequential for emotional and relational outcomes. Work Package 2 will identify the antecedents of perception-provision misalignment, establishing contextual, individual, and couple-level factors to see who is more at risk when. Finally, Work Package 3 will test a brief intervention to reduce misalignment between perception and provision of support. In determining when and why there are gaps between perceived and provided interpersonal emotion regulation, the project will generate practical methods to strengthen everyday social connection. </p>
