The Study

Primacy Effect 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.

The result

The results indicate that primacy effect significantly influences decision-making by altering perception, recall, or emotional response. These findings provide valuable insights into cognitive behaviour, informing design strategies.
