The article discusses how people make decisions when faced with risks. It suggests that individuals simplify decision-making by using different strategies based on their experiences and information. Decision-making involves breaking down complex structures into simpler ones, which can lead to changing preferences. The most effective way to simplify decision-making is by calculating expected value or focusing on a few key factors. The time taken to make a decision involves different stages, such as substitution and calculation time. The study also shows how decision structures can help explain paradoxes and anomalies in decision-making.
