This article offers a cognitive account of the means versus ends focus of e
nvironmental regulation. The first of two studies suggests that standards (
the means) exert an influence on judgments of proposed environmental soluti
ons that is independent of the extent to which those solutions protect the
environment (the ends). Standard-based decisions produce cognitive distorti
ons, artificially enhancing the attractiveness of standard-conforming solut
ions over that of nonconforming solutions. Our second study suggests that "
means" solutions tend to be preferred over "ends" solutions when one enviro
nmental proposal is examined. This pattern of preference can be reversed th
rough the simultaneous evaluation of two proposals.
