The current Atlas is an ESC application
The general multi-proxy approach is not limited to environmental behavior. The current Atlas focuses specifically on environmentally sustainable consumption (ESC), mapping the psychological characteristics of behaviors within this domain and providing tools for selecting proxies.
Why a behavioral map can help
Suppose you want to test whether an experimental effect depends on a behavioral characteristic such as normativity. Simply choosing behaviors that seem to differ in normativity may introduce other differences at the same time, such as effort or moral conviction. The Atlas allows you to examine these characteristics together, helping you select proxies more systematically and identify potential confounds.
The research question comes first
The Atlas helps researchers explore and select behavioral proxies, but it does not determine which selection strategy is most appropriate. That decision depends on the specific research question and the goals of the study.
