Explore the intersection of psychology and environmental modeling in this 59-minute Santa Fe Institute colloquium. Delve into the historical development of behavioral decision theory and its application to energy-related decisions and global low-carbon futures. Examine how non-rational decision processes are being integrated into climate change models, moving beyond traditional economic assumptions. Learn about an innovative collaborative effort to create agent-based models that incorporate individual decision processes and social network dynamics, potentially leading to tipping points in energy and climate-related behaviors. Gain insights into concepts such as Weber's Law, bounded rationality, query theory, and status quo bias, and their relevance to environmental decision-making. Discover how this integrative approach could contribute to understanding and promoting rapid behavioral changes needed to address climate change challenges.
