Session Description: 

This workshop focuses on practical investigation techniques, where credibility assessment will be considered from a legal perspective, but also from a psychological theories’ perspective. 

Some of the following questions will be considered: 

  • How much importance should be placed upon body language and “demeanour evidence”? 

  • Are investigators naturally skeptical, or naturally inclined to believe the evidence provided by witnesses? 

  • What are the common pitfalls of witness credibility assessment, and how may we avoid them? 

  • What role does cognitive bias play in credibility assessment?  

  • Are credibility assessment techniques impacted by a virtual/remote investigation environment?  

The workshop will include practical scenarios in which attendees will be encouraged to participate. 

Learning Objectives: 

Through attending this session, students will understand and be able to apply the following topics to their investigative practice: 

  • Credibility assessment skills, both in person and virtual

  • Underlying legal and psychological theories and concepts (e.g. demeanour evidence, truth-default theory) 

  • The impact of cognitive bias on credibility assessment
