Emotions Are Folk Concepts in a Predicting Brain.
Article in Brain sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The question "what is an emotion" is as old as the study of the mind and brain. Scientists from Western, English-speaking, Industrialized, Rich, and Democratic (WEIRD) nations tend to adopt certain definitions, but these definitions do not map onto the lived experiences of all people around the world. My approach to the question "what is an emotion?" is thus to accept that emotions are folk concepts that do not "cut nature at its joints." Instead, I draw from models of predictive brain function to ask, "how does the brain make mental states in general, and experiences that we call "emotions" in particular?" I discuss recent models of predictive processing and how it is thought that the brain gives rise to feelings of valence and, arousal, and how, in some cultures, categorical emotional predictions (e.g., "anger") might have evolved as a particularly useful class of predictions for navigating humans' social worlds.
