Resource scarcity, effort, and performance in physically demanding jobs: An evolutionary explanation

Area of Science:

• Evolutionary Psychology
• Organizational Behavior
• Environmental Psychology

Background:

• Evolutionary theory suggests environmental cues influence human behavior.
• Resource scarcity may trigger adaptive responses related to energy conservation.

Purpose of the Study:

• To test the prediction that environmental resource scarcity reduces effort and performance in physically demanding work.
• To explore the applicability of evolutionary psychology to organizational phenomena.

Main Methods:

• A 2-wave field survey with employees assessing perceived resource scarcity and job demands.
• An experimental study manipulating scarcity cues and measuring performance on tasks with varying physical demands.

Main Results:

• Employees perceiving resource scarcity exerted less effort in physically demanding jobs.
• Participants exposed to scarcity cues performed worse on high-physical-demand tasks, irrespective of financial incentives or actual energy needs.

Conclusions:

• Environmental resource scarcity can significantly impact employee effort and performance, particularly in physically demanding roles.
• Evolutionary psychology provides a framework for understanding these effects in organizational settings.
• Findings suggest implications for managing employee motivation and performance in contexts of perceived scarcity.
