New large scale registered replication project probing Construal-Level Theory.
It shows the typical pattern: Hundreds of published studies (with positive effects), but virtually no replication attempts. Metaanalytic bias correction suggests true effect close to zero.

The preregistered replication:

* N = 11,775 from 27 countries and regions; 99.995% power for g = 0.23
* direct and paradigmatic replications

Results (positive effects are consistent with hypotheses):

* temporal, d = 0.08, 95% confidence interval [CI] = [0.003, 0.16] (effect in original study: d = 0.92);
* spatial, d = 0.04, 95% CI = [−0.03, 0.11] (effect in original study: d = 0.55);
* social, d = −0.27, 95% CI = [−0.34, −0.19]; and
* likelihood, d = 0.03, 95% CI = [−0.05, 0.11].

"These findings provide limited evidence for the predictions of the theory and present a critical challenge for CLT.“

📄 "To Be FAIR: Theory Specification Needs an Update"

New paper in Perspectives on Psychological Science: https://journals.sagepub.com/doi/10.1177/17456916251401850

Semantic versioning of theories? Citable theory objects that are reproducible and published independently of classical papers?

Van Lissa et al. (2025) argue that psychological theories need clearer and more systematic specification. The paper adapts the #FAIRprinciples (Findable, Accessible, Interoperable, Reusable) – well known from open data – to the way theories are defined, documented, and communicated.

Adopted and donor-conceived children were way less likely to confound nature and nurture than traditionally-conceived kids (ages 4 to 8).

👨‍👩‍👧‍👦 And this difference wasn’t explained by differences in parents.

For baseball fans: research suggests complaining to umps gets you more favorable calls.

"After being excessively criticized, home-plate umpires (N = 110 adults, employed in the United States) were less likely to call strikes to batters from the complaining team and more prone to call strikes to batters on the opposing team."
