How does behavioral economics challenge the traditional assumptions of rational consumer behavior?

Traditional economic theories often assume that consumers are perfectly rational, always making decisions that maximize their utility. However, the growing field of behavioral economics suggests that this assumption does not always hold true. By incorporating insights from psychology, behavioral economists have identified a range of cognitive biases and psychological factors that influence decision-making. These include phenomena like loss aversion, anchoring, and overconfidence. Understanding these deviations from rationality provides a more nuanced view of consumer behavior and has significant implications for policies and business strategies. How do these insights alter our understanding of market dynamics and consumer power?
