The article explores how people make decisions when faced with complex problems. It suggests that individuals don't need to fully understand a problem to make choices; they can learn more by searching, but this comes with costs. The study shows that as problems become simpler or the benefits of searching increase, decisions become more rational. The costs of searching vary between people and across different problems. The research also explains why people sometimes make choices that don't seem rational. By looking at how the depth of search relates to the benefits, the model can be tested and used to predict how changes in outcomes affect decision-making. The findings help explain why people may act differently in various decision-making situations.
