From intention-behavior gap to dietary affordances: an active inference account of sustainable eating.
Article in Frontiers in psychology, 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
Faced with the urgent challenges of climate change and environmental degradation, governments, and frameworks like the EAT-Lancet Commission advocate for sustainable diets. Yet a persistent gap remains between individuals' intentions to eat sustainably and their actual behavior. Current approaches often attribute this gap to deficits in individual attitudes or motivation. In this paper, we challenge that view. We introduce the construct of dietary affordances to describe how opportunities for action emerge from the interplay between individuals and their environments. Drawing on ecological psychology and contemporary active inference accounts of perception and action, we formalize dietary affordance as a relative selection weight shaped by three components: pragmatic value
