Frequently Asked Questions
The feet and legs are directly linked to our ancient limbic system, which governs survival instincts. Long before humans developed complex language, our lower extremities evolved to react instantaneously to threats or rewards—such as turning toward an exit or preparing to flee. Because most people focus their conscious energy on controlling their facial expressions to mask emotions, they often neglect their feet, allowing honest "intention cues" and "gravity-defying" behaviors to leak out.
A baseline is the collection of normal, idiosyncratic behaviors a person displays when they are relaxed and comfortable. Establishing this "starting position" is crucial because every individual has unique quirks, such as nervous habits or specific postures, that might be mistaken for deception. By first observing how someone acts under normal conditions, you can accurately identify "deviations"—sudden changes in behavior that occur in response to a specific stimulus or question.
No. The script clarifies that many common beliefs, such as the idea that looking up and to the left or avoiding eye contact indicates lying, are nonvalidated myths. Science shows these behaviors do not reliably correlate with deception. Instead of looking for a single "Pinocchio effect" gesture, experts look for "clusters" of validated stress indicators and behavioral anomalies that suggest a person is experiencing discomfort or a high cognitive load.
Pacifying behaviors are tactile self-touching actions, such as stroking the neck, biting nails, or "leg cleansing" (rubbing palms on thighs), that the brain uses to calm itself down under stress. These behaviors are not proof of a lie; rather, they are indicators of discomfort. They signal that a specific topic has hit a "nerve," suggesting the area requires further exploration to determine if the stress stems from deception or a naturally difficult memory.
The framework breaks an interaction into four phases: when the question is asked, while the person processes it, when they answer, and the period immediately after they respond. By observing these windows, an interviewer can look for specific reactions like the "freeze" response, signs of "cognitive load" while constructing a story, a lack of physical commitment to the words spoken, and "cathartic breathing" once the person believes the danger of the question has passed.
