Many people have been falsely accused of wrongdoing at some point. In fact, several previous surveys have found that thousands of innocent individuals languish in our corrections facilities while the guilty ones remain on the outside.   

Intimidation in polygraph tests isn’t new. Indeed, cases abound where unprofessional examiners deployed underhanded tactics to extract confessions from examinees.  

Some polygraphers may threaten their subjects with severe consequences

Failing a lie detector test can be a distressing experience. But it’s not the end of the world. In fact, failing a polygraph test doesn’t necessarily imply guilt or deception. While a Deception Indicated (DI) verdict may cast severe aspersions

The United States and the United Kingdom are the two biggest users of polygraphs worldwide. The US alone conducts some 500,000 – 2.5 million lie detector tests annually. And while UK figures pale in comparison to that, the country reportedly

Doping is a nagging concern in professional bodybuilding competitions. Despite proactive efforts by many federations, hardly a month goes by without reports of acclaimed bodybuilders testing positive for performance-enhancing drugs (PEDs). Track-and-field

The human brain is the primary organ involved in truth suppression. While polygraphs don’t directly measure an examinee’s mindset, all tracked parameters are regulated by the brain and central nervous system (CNS).  Therefore, it’s unsurprising that many misconceptions 

John A. Larson is widely credited for inventing the modern polygraph machine. While many inventors preceded and succeeded him, Larson’s efforts laid the groundwork for the lie detector equipment as we know it today. Larson is perhaps best known

Polygraph evaluation is a rigorous process that requires a detailed, methodological approach. To make accurate inferences, examiners must carefully analyze the physiological data collected by the lie detector machine.  

Polygraph examination is a rigorous process that often culminates in careful data analysis.

Before inferring deception, examiners must determine whether the information collected is sufficient to enable accurate interpretation of the lie detector test findings.

When it comes to polygraph exams, there’s no one-size-fits-all strategy. Each lie detector test requires a unique approach. To conduct a credible polygraph evaluation, examiners must follow certain industry-stipulated guidelines. The question design rules typically apply across the board.
