The article suggests that seemingly irrational human decision-making can actually be explained by rational computational processes. By treating decision-making as a series of steps, the researchers created a model that predicts how people choose between options. The model considers factors like the information available, the effort needed to make a decision, and the limits of human cognition. It shows that what may appear as irrational behavior is actually a result of our brains trying to pick the best option based on available information and cognitive constraints.
