Psychological Science special issue call 📣 Ever had your research denigrated bc it's "only descriptive", "what's the mechanism though?" and "but what are the theoretical implications?" Now has come your time to shine. Send your best descriptive work! www.psychologicalscience.org/publications...
Psychological Science invites submissions that advance psychological science through careful description of psychological phenomena. Psychological research often focuses on explaining and predicting phenomena before we have a sufficiently detailed understanding of them. It can be difficult to build strong theories on incomplete empirical foundations of the phenomena themselves. Careful descriptive research helps establish shared empirical reference points developed around well-characterized phenomena. As such, descriptive research contributes to psychological science both by improving our understanding of the phenomena themselves and by providing a stronger foundation for future theory-building, explanation, and prediction.

We are interested in manuscripts that:

Deepen our understanding of psychological phenomena, including what they look like, how they vary, and how they unfold;
Draw on a variety of sources of evidence and methods, including qualitative, quantitative, and mixed-methods approaches; research conducted in naturalistic settings; intensive, longitudinal, or small-sample designs; and open or large-scale datasets; 
Provide necessary context for interpreting what is being described, including who is represented in the data, the settings and circumstances in which phenomena occur, and the broader social contexts in which they are situated; and/or
Make a substantive contribution to psychological science through the quality, depth, or significance of the description provided.
The deadline for submitting regular manuscripts is April 15, 2027. Registered Reports will also be considered. The deadline for submitting Stage 1 Registered Reports is November 15, 2026. Authors should indicate in the “Comments to Editor” box during submission that the manuscript is intended for the “Descriptive Research in Psychological Science” special issue.
