Deductive & Inductive Reasoning Flashcards

All armed robbery suspects must be photographed and fingerprinted. Marcus is a suspect in an armed robbery. Which conclusion is definitely true?

Answer: Marcus must be photographed and fingerprinted

The rule applies universally to all armed robbery suspects, so it must apply to Marcus.

Officer Reyes notices that the last four burglaries in the district all occurred between 2 AM and 4 AM on weekdays. What is the most reasonable inductive conclusion?

Answer: The burglar works a day job and strikes at night on workdays

The consistent pattern of weekday late-night timing inductively suggests the offender has daytime obligations.

If a vehicle is reported stolen AND the driver cannot produce a valid license, the officer must detain the driver. A driver produces a valid license but the car is reported stolen. What must the officer do?

Answer: Detain the driver because the stolen vehicle condition is still met with both together

Both conditions (stolen vehicle AND no valid license) must be present to trigger mandatory detention; here only one is met so the rule does not automatically apply — but the officer must still investigate the stolen vehicle.

Investigators find that three separate witnesses described the getaway car as dark-colored, four-door, and American-made. A detective spots a dark-colored, four-door Ford. What is the strongest inductive inference?

Answer: The Ford matches witness descriptions and warrants closer investigation

Matching multiple independent witness details raises the car's investigative priority but does not confirm guilt.

Policy: Officers must complete a use-of-force report within 24 hours of any incident involving force. Officer Chen used force during an arrest on Monday at 11 PM. By when must the report be submitted?

Answer: Tuesday at 11 PM

24 hours after Monday at 11 PM is Tuesday at 11 PM, regardless of shift schedules.

Every time Officer Park has responded to calls at a particular apartment complex, she has found at least one person without proper identification. She responds there again. What is the most reasonable inductive prediction?

Answer: She will likely encounter someone without ID based on the established pattern

Past consistent outcomes support a probable — not certain — expectation of a similar outcome.

No juvenile suspect may be held in the same cell as an adult suspect. Offender A is 17 years old. Offender B is 19 years old. Which statement is definitely true?

Answer: Offender A and Offender B cannot share a cell

Offender A is a juvenile (under 18) and Offender B is an adult, so the rule prohibits them from sharing a cell.
