Is too much personal dread stifling alternative pathways to improving urban water security?

Area of Science:

• Environmental Psychology
• Water Resource Management
• Decision Science

Background:

• Water resources face dire prognoses due to urbanization and climate change.
• Traditional water planning persists despite emerging threats.
• Psychological risk perception, particularly dread, influences decision-making in other fields.

Purpose of the Study:

• To investigate if psychological biases, specifically dread, affect water practitioners' risk perceptions.
• To assess the impact of cognitive bias on decision-making regarding alternative water projects.
• To analyze the relationship between personal biases and risk scores in the water sector.

Main Methods:

• Survey methodology based on risk psychology (Slovic et al., 1985).
• Psychometric testing of 77 water practitioners in Melbourne, Australia.
• Analysis of cognitive biases influencing risk perception and decision-making.

Main Results:

• A significant role of 'Dread' in the variation of risk scores among participants.
• 'Fear of the Unknown' and 'Dread related to perceived fatal risk' were statistically significant factors.
• Cognitive bias demonstrably influences risk perception in water planning.

Conclusions:

• Feelings of dread may inflate risk scores, hindering the adoption of alternative water projects.
• Understanding psychological influences is critical for effective water resource planning.
• Addressing cognitive biases can improve decision-making for sustainable water management.
