It discusses how memory can mislead investigators, leading to wrongful convictions, and highlights the gap between popular myths about criminal profiling and the realities of forensic psychology. Host Sana Qadar invites listeners to question confident but faulty assumptions and to explore the tools used to crack cases with humility and scientific caution.

• Memory reliability governs evidence handling and justice.
• Nonverbal behavior is a poor stand-alone lie detector.
• Profiling serial killers is often off the mark.
• The episode emphasizes critical thinking and myth-busting in forensic science.
