Critical Thinking and Analysis Flashcards

An officer notices that a store's alarm is sounding, the front door is ajar, and a car is idling nearby with no one inside. What is the MOST logical initial conclusion?

Answer: A possible burglary is in progress or just occurred

Multiple converging indicators — alarm, open door, and abandoned running vehicle — most logically suggest a burglary in progress or recent crime.

Which of the following is an example of a hasty generalization?

Answer: Two officers responded to similar calls this week, so crime must be rising citywide

Concluding citywide crime is rising based on only two incidents is a hasty generalization drawn from an insufficient sample.

A supervisor receives two conflicting reports about the same incident from two officers. The BEST first step is to:

Answer: Identify specific points of disagreement and seek corroborating evidence

Identifying specific conflicts and seeking additional evidence is the most analytically sound approach to resolving contradictory accounts.

If every officer on Watch A completed their report on time last month, and Officer Davis is on Watch A, what can be concluded?

Answer: Officer Davis completed reports on time last month

The only valid deduction is that Officer Davis completed reports on time last month, since that is directly stated in the universal premise.

An investigator is reviewing surveillance footage and notices a suspect enters a building at 9:02 AM and exits at 9:47 AM. The crime occurred between 9:15 and 9:30 AM inside the building. What does this evidence establish?

Answer: The suspect had opportunity to commit the crime

The footage establishes that the suspect was present during the crime window, proving opportunity but not guilt.

Which reasoning pattern is demonstrated here: 'Crime rates drop whenever more officers are on patrol. We added patrols last month. Therefore, crime dropped because of the patrols.'

Answer: Post hoc ergo propter hoc fallacy

Assuming that because patrols increased before a crime drop, patrols caused the drop is a post hoc fallacy — correlation is not causation.

A witness states: 'I'm not totally sure, but I think the car was either blue or green.' How should an investigator treat this statement?

Answer: Note it as tentative information to be verified with other evidence

Uncertain witness statements should be recorded as tentative leads to be corroborated, not accepted as fact or discarded.
