Encounter Norm Analysis
Encounter norm analysis is the normative-survey pipeline used to set standards for visitor impacts in parks and protected areas. Building on Vaske, Shelby, Graefe, and Heberlein's 1986 formalization of backcountry encounter norms, it asks recreationists to evaluate the acceptability of a range of conditions — most classically the number of other groups encountered per day, but also people at one time, campsite sharing, or depicted impact levels — and aggregates those evaluations into a social norm curve. The curve locates the minimum acceptable condition where acceptability crosses from positive to negative, supplying a defensible numeric standard. The method also quantifies the structural properties of norms: their intensity (how strongly conditions are evaluated), prevalence (whether respondents hold a norm at all), and crystallization (the degree of agreement), the last now commonly indexed by the Potential for Conflict Index (PCI2). Robert Manning's synthesis in Parks and Carrying Capacity made this normative approach the empirical core of indicators-and-standards frameworks.
