How influence personality traits during polygraph instrument?

Personality traits can significantly influence an individual's responses during a polygraph test, as traits like anxiety or sociability can affect physiological reactions such as heart rate or perspiration. For example, a highly anxious person may exhibit heightened physiological responses due to stress rather than deception. Conversely, someone with high emotional stability might remain calm, potentially skewing results. Thus, understanding a test subject's personality is crucial for accurately interpreting polygraph data.
