  3. Data Interpretation: Interpreting the data captured by the polygraph machine requires an analytical mind, an understanding of human behavior, and meticulous attention to detail.
  4. Emotional Intelligence: Polygraph examiners need high emotional intelligence to make examinees feel comfortable and interpret non-verbal cues accurately.
  5. Ethical Conduct: Conducting a polygraph examination is governed by a strict code of ethics that ensures fairness, respect for examinee rights, and confidentiality protection. Adherence to these ethical standards is crucial for maintaining the integrity of the test results.
