What is it?

Survivorship bias occurs when analysis focuses only on users or outcomes that completed a journey, while ignoring those that dropped out.

This bias can distort interpretation.

• Reviewing feedback from successful journeys only
  
• Overestimating experience effectiveness
  

Typical Outcomes / Results

• Incomplete understanding of behaviour
  
• Missed optimisation opportunities
