Is there a measurable psychological benefit to being able to regularly see the horizon, vs living in an urban setting with occluded sightlines.

There is strong evidence that exposure to natural environments and greenspace confers measurable psychological benefits (reduced stress, improved mood, better attention/cognition) compared to urban settings. However, the specific claim about *horizon visibility* or *open sightlines* per se is not directly tested in the available literature; benefits are attributed to nature exposure broadly, and some related work on 'prospect' (open views) from biophilic design and Kaplan's restorative environments theory suggests open vistas may contribute, but this is inferred rather than directly measured.

Largest vulnerability: Moderate uncertainty — methodological concerns is the main limit: 69% of sources rated medium-or-low quality.

The competing claim

Psychological benefits attributed to natural environments may be primarily driven by physical activity, social interaction, and pollution reduction rather than visual access to nature or open sightlines per se.

These systematic reviews acknowledge that confounding variables — including increased physical activity, reduced air and noise pollution, and greater social cohesion in green spaces — may account for much of the observed benefit. This diverges from the consensus by suggesting that visual features like horizon visibility or open sightlines are not independently causative. The counter-claim risks a correlation/causation confusion: because greenspace, physical activity, and open views co-occur, isolating the visual component is methodologically fraught, and attributing benefits to any single factor (including prospect/horizon) may involve cherry-picking the mechanism that fits a preferred theoretical narrative.
