Cutting edge behavioural science for real world applications

Evaluating truthfulness and credibility

This is a four-day programme based on solid research and science, designed to develop a person's ability and skill to recognize emotions in others as a basis for evaluating truth and lies.

Psych model LiesIt covers the psychological models behind truth and lies, plus the skills required to identify 'Hotspots' - instances when the strain between what we are thinking and what we are feeling produce observable/audible leakage across the five channels. The course is designed to help you to read and evaluate the degree of truthfulness and credibility in what others are communicating to you.

As well as the unique, five channel approach to training you will also learn about memory, and how you can work out whether a statement of an event is remembered or being constructed through scientific content analysis.


You will practice and hone those skills in a safe environment with Paul Ekman Approved Trainers. The courses are enriched with unique content, using videos of truth-tellers and liars from high-stake cotexts such as international Embassy visa applications, scientifically validated experiments conducted by Prof Paul Ekman himself and extracts of CEOs from commercial investment contexts. We also use live practice sessions to help delegates build knowledge, skills and application with high quality feedback from the Paul Ekman Trainers.

A graded Certificate of Competence will be awarded to you on completion.

  • Identify the importance of baselines and when they occur
  • Take a structured approach to the detection of leakage
  • Identify and evaluate 'hotspots'
  • Carry out hypothesis testing
