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.

Actionable tips

1.

Present key info first for better recall.

2.

Use strategic sequencing to influence decisions.

3.

Test order effects for optimal messaging.
