The study looked at how people's emotions and thinking affect their decisions about investing in property. They found that using mental shortcuts (heuristic) and following others (herding) can lead to irrational investment choices. The researchers studied 100 investors in Surabaya and found that heuristic behaviors like making decisions based on limited information significantly influence investment decisions. However, overconfidence and herding did not have a significant impact. Men are more likely to exhibit heuristic and herding behaviors compared to women, and experienced investors are more prone to these biases than inexperienced ones.
