Can a sociopath pass a lie detector test if they are lying?

Yes, a sociopath can potentially pass a lie detector test even when lying. Lie detectors measure physiological responses such as heart rate and galvanic skin response, which can be influenced by anxiety and stress. Sociopaths may lack the emotional responses that typically trigger these physiological changes, allowing them to remain calm and potentially deceive the machine effectively. However, the accuracy of lie detector tests is still debated, and various factors can influence their reliability.
