The Study

Peak-End Rule explores how individuals' decisions and perceptions are influenced by underlying psychological mechanisms. Research on this bias has revealed its role in everyday behaviours and decision-making processes. Studies often involve experiments where participants' reactions are observed to determine the bias's impact. This understanding helps designers and marketers craft more effective, user-centric experiences.
