The study aimed to measure how people make decisions about their health using a theory called Prospect Theory. The researchers found that people are more afraid of losing something than they are happy about gaining it. They also discovered that people are more likely to take risks when there is a chance of a big gain. However, when it comes to losing something, people are more cautious and prefer smaller losses over bigger ones. These findings suggest that when it comes to health decisions, people's behavior is influenced by their fear of losing something important.
