Psychometric framework for coexistence with large carnivores

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...
