Evaluating Truthfulness and Credibility (ETAC) Course

What You’ll Learn

In most interactions, individuals put too much emphasis on the spoken words. This approach results in a significant loss of information and is ineffective in assessing the credibility of others.

The Evaluating Truthfulness and Credibility course 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.

Participants will learn how to read and evaluate others through their verbal and nonverbal behaviors and use this skill to accurately evaluate their credibility or uncover any deception.

During this program you will go far beyond just analyzing the words, you will learn how to read and interpret all 5 core channels of communication (facial expressions, body language, the voice, verbal style, and verbal content) and how these can be used to expose the true thoughts of others.

Among the content covered is:

  • Identify the importance of baselines and when they occur
  • Take a structured approach to the detection of leakage
  • Identify and evaluate ‘hotspots’
