Kahneman's Insights for Climate Risks: Lessons from Bounded Rationality, Heuristics and Biases

Area of Science:

• Behavioral Economics
• Environmental Economics
• Climate Change Adaptation

Background:

• Daniel Kahneman's work significantly impacts environmental economics, leading to behavioral-environmental economics.
• Focuses on individual decision-making regarding climate change risks and deviations from rational behavior.

Purpose of the Study:

• To review the application of Kahneman's theories in environmental economics for climate adaptation decisions.
• To analyze how cognitive biases influence climate risk perception and preparedness.

Main Methods:

• Scoping review of existing literature.
• Analysis of methodologies including household surveys and economic experiments.
• Examination of factors like loss aversion and heuristic thinking (System 1 vs. System 2).

Main Results:

• Kahneman's theories explain suboptimal individual preparedness for climate change.
• Identified cognitive biases (loss aversion, underweighting low probabilities, System 1 thinking) impact adaptation choices.
• Diverse methods reveal how these biases affect investments in resilience and insurance.

Conclusions:

• Kahneman's legacy provides a framework for understanding and addressing maladaptive behaviors in climate adaptation.
• Policy strategies like risk communication, nudges, and financial incentives can enhance disaster preparedness.
• Future research should systematically assess Kahneman's ideas across climate contexts and for broader environmental issues.
