8.4 Separating Stated Facts From Assumptions
Key Takeaways
- A stated fact is written in the prompt; an assumption is added by the reader.
- The official brief warns that previous experience and outside knowledge are not required.
- Trap answers often sound reasonable while depending on an unstated fact.
- Fact separation is useful for both law-enforcement and corrections scenario settings.
Do Not Supply Missing Facts
The official source brief says CJBAT exams do not require previous experience or outside knowledge. Candidates should use only the material provided in questions or passages. That is one of the most important rules for Deductive Reasoning.
A stated fact is information the prompt gives you. An assumption is information you add. Assumptions may come from common sense, personal experience, television, workplace habits, or guesses about law enforcement and corrections. Even when an assumption is plausible, it is not a valid deduction unless the prompt supports it.
For example, the brief says FDLE says the test is administered only within the state of Florida. It also says registration is available online through Pearson VUE. A valid conclusion keeps those facts separate: online registration does not change the Florida administration rule.
Another example involves results. Pearson VUE provides unofficial results on the day of testing. Official results are recorded in FDLE's ATMS. A valid conclusion is that unofficial same-day results and official ATMS records are different concepts. An unsupported answer would merge those two result sources.
| Prompt detail | Stated fact | Unsafe assumption |
|---|---|---|
| Registration is online. | A candidate can register online through Pearson VUE. | Registration method changes the testing-location rule. |
| Testing is Florida-only. | Administration is only within Florida. | A location exception exists without being stated. |
| Results are pass/fail. | Candidates, academies, and agencies receive only pass/fail. | Another candidate-facing score format exists. |
| Retake fee required. | A new examination fee is required for each retake. | A free retake exception exists without being stated. |
When an answer feels familiar, slow down and ask whether the prompt actually supplied it. Familiar language can hide a missing condition, especially when a question uses an official-looking setting.
A useful habit is to label each answer choice. Write S in your mind for supported, C for contradicted, and N for not enough information. The correct deductive answer is usually supported. Contradicted choices are wrong. Not-enough-information choices may sound possible, but they do not necessarily follow.
This habit protects candidates in scenario settings. The brief says law enforcement scenarios are mostly law-enforcement contexts and corrections scenarios are mostly correctional facility contexts. That does not authorize the reader to import agency procedures. The prompt controls the reasoning.
Use this assumption check:
- Ask, "Where did the prompt say that?"
- Separate online registration from testing location.
- Separate unofficial results from official ATMS records.
- Separate eligibility from hiring or ranking.
- Treat possible facts as not proven unless stated.
- Choose only what must follow.
Deductive Reasoning is often less about complex logic and more about discipline. If you refuse to add facts, many trap answers become visible. The answer that stays inside the prompt is usually stronger than the answer that sounds detailed but brings in unsupported material.
