Behavioral scientists and police use ________ to narrow criminal investigations to suspects who possess certain behavioral and personality features revealed by the way the crime was committed.

• A. Brain scans
• B. Criminal profiling
• C. K9 units
• D. Polygraph measures

Answer: (B)

Profiling uses how the crime was carried out to infer the offender’s behavioral tendencies and personality traits, then narrows the suspect pool to those who fit that inferred profile. By examining the crime scene, investigators look at patterns in the offender’s actions—the modus operandi, any signature elements, level of planning, control, and victim choice—to build a psychological sketch of who might have committed the crime. This helps focus interviews and investigations on individuals whose behaviors and traits align with the inferred profile, making the search more efficient. Brain scans aren’t used to identify suspects based on personality in real investigations, and K9 units are primarily search and detection tools rather than methods for inferring offender characteristics from crime scenes. Polygraph measures assess physiological responses to questions and aren’t reliable or commonly used to narrow suspects by behavioral traits in standard investigative practice.
