🧠 Why:

Emotional memory is harder to fake consistently.

Truthful people:

• Recall genuine feelings
• Show natural emotional variation

Liars may:

• Over-exaggerate emotions
• Sound flat or rehearsed
• Change emotional tone when repeated

🔄 7. “Has anything changed in your version of the story?”

This encourages self-correction.

🧠 Why:

Liars may:

• Adjust their story when pressured
• Forget earlier statements
• Unintentionally contradict themselves

Truthful people are usually more consistent.

🧠 Important reality check

These questions do NOT guarantee that someone is lying.

👉 There is no single “lie detection question”
👉 Human memory is naturally imperfect
👉 Stress can also cause inconsistencies

Even truthful people may:

• Forget details
• Misremember timelines
• Confuse sequences

⚖️ Signs of possible deception (not proof)

Psychologists look for patterns like:

• Changing versions of the same story
• Avoiding specific details
• Overly rehearsed answers
• Excessive or unnatural detail in some areas but not others

👉 But none of these alone confirm dishonesty.

🧠 Why interrogations use open-ended questions
