Face image resolution and perceived attractiveness: An 8K display study.
Article in PloS one, 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
backgroundFacial attractiveness is shaped by multiple visual cues, yet the influence of image resolution on attractiveness judgments remains underexplored. Advances in display and imaging technology now allow for image presentation at resolutions approaching the limits of human spatial vision, enabling investigations under higher-fidelity spatial sampling conditions that more closely approximate retina-like detail at typical viewing distances.
objectivesThis study aimed to determine whether facial image resolution, specifically matched to the spatial resolving power of the human visual system, affects perceived facial attractiveness.
methodsHigh-resolution facial images of 180 Japanese female models were captured using an 8K imaging system (7680 × 4320 pixels; 283.2 ppi). Low-resolution versions (35.3 ppi) were created by downsampling the originals using pixelation. Both high- and low-resolution images were presented on an 8K display in a within-subjects design. Participants rated the attractiveness of each face using a standardized 6-point scale.
resultsFacial images presented at higher resolution received slightly higher attractiveness ratings than their low-resolution counterparts, as confirmed by linear mixed-effects models accounting for crossed observer and identity effects. The effect was especially pronounced for faces with higher baseline attractiveness. Age-related declines in attractiveness ratings were observed in both conditions.
conclusionsUltra-high image resolution yields a small but reliable increase in perceived facial attractiveness, particularly for faces with higher baseline attractiveness. These findings suggest that increased spatial detail may amplify attractiveness-related cues that are otherwise diminished in conventional-resolution displays.
