The Differential Psychology of Environmental Protection/Exploitation

Differential psychology focuses on how people vary in the way they think, feel and act by measuring differences that distinguish individuals as more similar to themselves over time and across situations than others. In this article I review and discuss available evidence on key individual differences associated with protection and exploitation of the natural environment. The discussion centers on personality traits, basic human values, time perspective and system-justifying ideological orientations. Greater environmental protection has been shown to be consistently related to higher levels of Openness to Experience and Agreeableness traits (and somewhat Honesty-Humility), Self-Transcendence and Openness to Change values, and future thinking. In contrast, greater environmental exploitation is consistently related to higher levels of conservative political orientation, Right-Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). Research examining individual differences provides useful theoretical information that can have applied benefits in designing communication strategies to bring individuals less prone to protect the natural environment on board. Issues with jangle fallacy (measures with different names might not necessarily assess different things) and direction for future research are also discussed.
