personalitymap.io is an AI driven tool that integrates known individual differences correlations into a database that allows searching and extrapolation to scale items that don't exist yet. In June, they announced the expansion of their scope to cover an even wider set of items and variables, including the DSM personality disorders. Registration to use the tool is free.

It is well-known from twin studies that some psychological traits display evidence of being heritable (passed-on from parent to child). But large, high-powered genetic studies have found some genes that explain only a small amount of the supposed heritability. This "missing heritability" has led to debates about whether the evidence for heritability is flawed. Scott Alexander in a blog post does a good and even-handed job of explaining the problem and debate.

Your friendly neighborhood dominatrix might be more well-adjusted than you, or so we might conclude from findings covered by psypost.org. In a paper published in the Journal of Homosexuality, Oscar Lecuona and colleagues surveyed 1,907 people in Spain on a range of individual difference variables as well as their participation in BDSM activities. It as found that "BDSM participants were more likely to have secure attachment styles, lower rejection sensitivity, and higher levels of well-being"

In a recent paper to be publihsed in the Journal of Experimental Psychology: General, Tal Boger, Sami Yousif, Samuel, McDougle, and Robb Rutledge report that there seem to be stable individual differences when people are asked to perform "randomly", that these seem to persist across different tasks, and even more interestingly, could display consistency evern after 1 year later. Whatever process, strategy, or interpretation of "randomness" that people rely on, it appears to be different for different people but also remarkably stable.

An article in the APA Monitor on Psychology magazine talks about efforts to set up "adversarial collaborations". These are projects where scientists who have strongly contrasting theories or hypotheses work together to test whose account is better supported. This way of doing research is meant to increase rigor and trust in the findings achieved.

Itai Yanai and Martin J. Lercher, in a letter published in Nature, talk about something that most personality psychologists already know: that trait Openness is implicated in scientific creativity. While they seem to rebranding familiar things (turning "context of discovery" into "night science") and putting forward unorthodox takes (Openness as a "skill"), the essay is useful in that it introduces a wider scientific community to research on personality traits.

At the recent IAFOR 2025 Conference on Psychology & the Behavioral Sciences, Luan Nguyen Huynh of RMIT University Vietnam presented new findings on the connection between alexithymia—a personality trait marked by difficulty in recognizing and describing one’s emotions—and interoceptive sensibility, or the ability to sense internal bodily states. The study found that individuals who struggled more with emotional clarity also reported lower sensitivity to internal bodily cues. Two specific dimensions—how vividly people perceive bodily sensations and how much they trust those signals—were especially linked to levels of alexithymia. The study serves as a valuable reminder that personality traits like alexithymia are not just cognitive, affective, and behavioral—they also have physiological and perceptual components.

A study published in Personality and Individual Differences and reported in psypost.org claims to find evidence that some basic moral positions are heritable. Timothy C. Bates used data on 439 identical twins and 627 fraternal twins from the Brisbane Adolescent Twin Study, together with responses on the Oxford Utilitarianism Scale to estimate an overall heritability of 52%. It should be noted though that heritability estimates also reflect cultural context, which may magnify or minimize genetic influence on behavior (see Uchiyama, Spicer, and Muthukrishna for an excellent explainer).

AJ Galang, PIRLab's very own coordinator, facilitated a workshop on a new framework for teaching and theorizing about personality. AJ calls this approach "The Psychological Imagination", which sets out a meta-theory that describes, in broad terms, what a personality theory should be able to do. He also introduced the "Simulation Project" as an assessment method for teaching undergraduate personality psychology. Future workshops that will elaborate on specific aspects of the framework are planned for the later part of 2025.
In a preprint of a study that is due to be published in the journal Psychological Review, Dorsa Amir and Chaz Firestone review the evidence that perception of the famous Müller-Lyer illusion (https://en.wikipedia.org/wiki/Müller-Lyer_illusion) is dependent on culture. They claim that once methodological differences are accounted for, the Müller-Lyer illusion might be less dependent on culture than we previously thought. There was immediate pushback from some cultural psychologists on social media, so expect a lively debate and rejoinders to this paper in the near future.

Even for personality psychologists, the image of a narcissist as someone so self-absorbed so as to lack awareness of what others are doing and saying might be tempting. At the same time, there is agreement that social context matters for personality traits. Reconciling these two intuitions, a study published in the Journal of Research in Personality found that indeed state narcissism (personality tendencies in the situation) was affected by perceived features of the situation, and vice versa. For example, if the person thought that the situation was fun and enjoyable, the state of naricissistic agency was higher on average. Apart from the findings, what makes this paper from Sophie C. Bauditz, Aidan G.C. Wright, Ursula Hess, and Matthias Ziegler such an interesting read is how they used repeated controlled interpersonal interactions and sophisticated longitudinal modeling to analyze how past states and perceptions affect future states and perceptions.

AI news is always hot news these days, so it isn't surprising that the APA posted a press release about an article recently published in the journal Psychology of Aesthetics, Creativity, and the Arts, giving it the reassuring headline "Professional artists viewed as more creative than AI programs". Except of course that that wasn't what the study was about, and that is clear even from just reading the press release. It actually compared 15 professional artists against 15 people with no artistic training, and both groups were asked to provide prompts for an image generation program. That the professionals fared better doesn't seem surprising, nor is it fair to characterize the non-artist humans as being merely "AI programs". But the actual article from Paul Seli and colleagues is probably more interesting without the hype so you should go read it for yourself.

Why do we like sad art? In a series of experiments published in Cognitive Science, Venkatesan et al. examined two competing hypotheses: we like sad art because it's not real, we are safe from it, and we can thus appreciate the merits of the piece from a detached distance (fictionality hypothesis), or we like sad art because it expresses our own emotions (appropriation hypothesis). Through mixed-effects modeling and mediation analyses, the authors found more support for the appropriation hypothesis. Generally, people expressed more liking when a piece is described as art (short story, poem, etc) vs nonart (blog post, tweet). This liking was mediated by the extent to which the participant felt that the emotions expressed in the piece also expressed the participant's own emotions. On the other hand, if a piece is presented as fictional, there is decreased liking for it. These results suggest that the maxim "Art as self-expression" may not just be talking about the artist's self-expression -- it involves the audience's as well.

In an episode of the Personality Psychology Podcast hosted by René Mõttus, two researchers talk about the use and impact of AI on scientific personality research. Both of the guests, Sandra Matz and Michal Kosinski (the latter notable for conducting some of the first large-scale studies using Facebook data to predict personality traits) express both optimism and caution about the abilities of language models to understand human personality. We might point out that the correctness of LLM-based understanding of personality depends on how correct the current theoretical literature is, which is something we cannot take for granted.

Two decades ago there was enormous hype around techniques like the Implicit Association Test (IAT), which then spawned whole literatures and pop-psych trends (contributing to the spread of ideas like "implicit racism"). While procedures like the IAT are not valueless, Olivier Corneille and Bertram Gawronski, writing in Nature Reviews Psychology, offer a welcome anti-hype paper unambiguously titled "Self-reports are better measurement instruments than implicit measures". They even include a helpful explanation of a technique that allows you to use self-reports to study automaticity in cognition. The article is unfortunately paywalled (thanks, Nature) but the authors have shared full-text access to people to ask for it.

We all know that if a respondent skips an item in a summated psychometric scale we cannot just assume their answer as "zero", which makes this troublesome for our analyses. With the statistical technique of multiple imputation, missing data doesn't have to mean a smaller sample size. Although it sounds like cheating, multiple imputations allow you to predict what the missing quantities would have been using a firm principled procedure (assuming that you know what you are doing). Quanta did a very accessible explanation of the history and rationale behind this statistical equivalent of a Photoshop touch-up.

The idea that our lives and our sense of self is a narrative has become so ubiquitous in the social sciences that it feels like there could be no alternative. That by itself should be a warning signal that we are becoming complacent. The good news then, is that in an essay for Psyche/Aeon, Karen Simacek offers an alternative point of view.

Procedures like the "trolley problem" find that different people will have different responses. Often we interpret this as evidence that people have stable individual differences on moral issues. But what if that wasn't the case? A paper from one of the leading researchers in experimental philosophy, Joshua Knobe, to be published in Ergo: An Open Access Journal of Philosophy argues that there is evidence to show that a better picture is that people often have conflicting philosophical intuitions. This seems to imply that the variance in philosophical reasoning data could be mainly within-person rather than between-person variance. In related news, an interesting online questionnaire claims to measure the degree to which your philosophical intuitions are consistent (or not). We cannot vouch for its psychometric validity.

In an essay for Aeon/Psyche, Stephen Gadsby and Sander Van de Cruys argue that it was incorrect to think of conspiracy theorists as passive consumers of disinformation. Instead, they point to the possibility that such people are motivated in large part by the excitement of discovery and the desire to have insight ("aha!") experiences. This ties nicely with Neil Levy's "serious play" hypothesis of conspiracy theorists.

The UP PIRLab, in partnership with the Pambansang Samahan sa Sikolohiyang Pilipino (PSSP), facilitated a two-day workshop on August 1 to 2 on pagsasakatutubo (indigenization) of psychological research methods. Topics such as experimentation, psychometrics, and assessment were covered.
AJ Galang presented a paper about the problem of student creativity measurement at the National Conference on Educational Measurement and Evaluation (NCEME 2024), which was hosted by De La Salle University from August 29 to 31. AJ explained how the psychometric issues surrounding creativity measurement should make us cautious about making policies based on the PISA 2022 creative thinking results, which showed that Filipino students scored poorly. The organization behind the NCEME, the Philippine Educational Measurement and Evaluation, Inc. (PEMEA), awarded AJ with one of the best paper recognitions for the conference.
We often think that people who are organized and focused in the way they approach their lives probably do so by exerting effort and willpower constantly to avoid distractions or temptations. In effect, we think that state self-control explains trait self-control. In a paper published in Current Opinion in Psychology, Michael Inzlicht and Brent Roberts effectively dismantle this idea and argue that trait self-control is mostly independent and is not predicted by state self-control. Highly recommended read.

The PIRLab convened a group psychological scientists on the 18th of July to discuss the results of the PISA 2022. The latest round of the international assessment of high school students included items that were meant to assess "creative thinking". The group concluded that there were psychometric issues which greatly limit how relevant the PISA 2022 might be assessing and improving the creativity of Filipino students. The PIRLab decided to take the lead in drafting a policy brief that would state the group's position on the issue. It should be noted that the Philippines ranked very low on "creative thinking" among the countries included in the last PISA

AJ Galang facilitated a workshop on the use of psychophysiological methods for graduate students and faculty on 19 July. The training session covered gaze and pupil recording techniques, electroencephalography (EEG), electrocardiography (ECG), and electrodermal activity (EDA).
Over at The Psychologist, which is the blog/digest of the British Psychological Society, Naomi Fisher writes about how the diagnostic categories that were invented to guide clinical practice are increasingly being appropriated and reframed by lay people as social identities. This seems to be part of a larger trend where people, especially the young, are seeking ever more specific forms of belonging by self-diagnosing or self-labeling and seeking like-minded people (often online).

Finally, it seems not a year goes by without someone claiming to discover a single latent factor for something that explains everything. We've already seen single factors for personality and psychopathology, all of which are very dubious. A new paper in PNAS claims to have found a single factor for "impulsivity". Thankfully, Eiko Fried and Orestis Zavlis were immediately on the case and have done a very good job of deflating these claims (especially on why bifactor models should always be viewed with suspicion; Google for "fit propensity" to find out more).

A major review paper covering personality psychology research on what predicts scientific creativity was published in the open-access journal Collabra: Psychology, the journal of the Society for the Improvement of Psychological Science. The paper points out unresolved issues about this field and how to incorporate or test previous findings with the changing nature of careers in science in the 21st century.

The open-access journal Personality Science announced its relaunch. As the official publication outlet of the European Association of Personality Psychology, the journal had already been operating since 2020. As the front page of their official website states, "The journal publishes highest-quality theoretical, methodological, empirical, applied, and commentary papers continuously once they are ready – exclusively in an online open-access format (i.e., with no article processing charges or paywalls)."

Although it is a very vague term, it is often pointed out that one thing that is similar between Rodrigo Duterte, Donald Trump, Boris Johnson, Jair Bolsonaro, and many other politicians of a similar vein is that they are populists. This roughly means that they claim to represent "ordinary people" against some demonized "elite". PsyPost reported on a study published in the journal Electoral Studies that found links between Dark Triad personality traits (Machiavellianism, Narcissism, Psychopathy) and having populist leaning attitudes. The good thing about the study is that it had a decent sample size (more than 6,000 across a few European countries), but on the other hand they used short versions of the already brief Short Dark Triad scale, and the infamous Ten Item Personality Inventory (TIPI) which, to put it mildly, is not a very good measure of personality traits.

It might be that some people neither choose their lives to be happy and enjoyable, nor be something full of meaningful achievements. Shigehiro Oishi and Erin Westgate had previously explored the possibility of a third dimension (or is it mode?) of what might be considered a "good life" by articulating the notion of a "psychologically rich" life focused on exploration and change. In a new paper with Youngjae Cha, they tried to further characterize the differences between these forms of the good life by investigating whether they are differentially related to measures of cognitive complexity (e.g. whether they prefer simple vs. complex explanations, or whether they prefer to consider things holistically). In an initial study (n = 436, US sample) and in a pre-registered replication (n = 516, US sample) published in the Journal of Research in Personality, they consistently found that a psychologically rich life was associated with more attributional complexity and holism, but the other dimensions were not. This is further reason to believe that possibly there is indeed something distinctive about lives that seek something else other than happiness or meaning.
