Your nervous system is still scanning for predators

Jay Appleton’s Prospect-Refuge Theory proposes that humans carry an evolved preference for environments offering prospect (a wide view, the ability to see) together with refuge (enclosure, protection from behind). His formulation is that because the ability to see without being seen is an intermediate step in satisfying many survival needs, an environment’s capacity to deliver it becomes a source of aesthetic satisfaction in its own right.

The theory is a proposal about why certain spatial arrangements feel better, not a measurement of the nervous system. It would predict that a chair with its back to a wall settles an occupant more than an open-backed seat, and that a position diagonal from the entrance reads as commanding rather than exposed. Those predictions have been tested since, with results that are genuinely mixed (see Dosen and Ostwald below). We present Appleton as the framework that named the pattern, not as settled evidence.

Dosen and Ostwald gathered and classified the quantitative research that has tested prospect-refuge theory and closely related parts of environmental preference theory. Their stated purpose was not to judge the rigour of that past research but to sort what it actually found, for and against, into a picture the design disciplines could use. They open by noting that the evidence design professions usually cite for these ideas is largely qualitative.

The results split by setting. Urban and interior studies supported the significance of prospect, and were more neutral about refuge. Studies of natural environments provided evidence for both prospect and refuge, linked to comfort, but also included evidence against and a neutral finding. Complexity in interior space was generally preferred, with no clarity on how much or where. Mystery came out mostly neutral or contrary. Their conclusion is that the quantitative evidence remains inconsistent, and that it is particularly problematic that the results most often cited in architecture come from studies of natural environments rather than interiors or urban settings.
