Avoiding Outside Assumptions

The cardinal rule: answer from the passage only

The single most damaging mistake in reading comprehension is importing information the passage never states. Candidates who have worked in security, watched corrections shows, or simply have strong common sense are especially prone to it, because their outside knowledge feels reliable. On the test it is a liability. The exam is measuring whether you can read a document and apply its words — not whether your independent judgment is good. Every time you choose an answer, you should be able to point to the sentence that supports it. If you cannot, you are assuming, and assuming is how candidates lose otherwise easy points.

This matters on the job too. An officer who acts on "what we usually do" instead of the current post order or directive can violate policy, override a supervisor's authority, or miss a step that protects safety and accountability. The exam's insistence on textual fidelity mirrors the professional value of policy adherence. So the test answer and the right professional habit point the same way: do and conclude only what the written source supports.

Four kinds of outside assumptions to refuse

The traps cluster into recognizable types. Train yourself to name them when they appear.

The last one — filling a gap — is subtle. When a passage is silent on a point, the correct reading is usually that the passage does not address it, not that you may supply the missing rule. A question that asks "Based on the passage, what should the officer do about X?" when the passage never mentions X often has a correct answer like "the passage does not provide guidance on X" or an answer that stays inside what the passage does cover. Resist the urge to invent the missing piece.

Inference is permitted, but only the strict kind. A valid inference must follow from the passage — if the passage says every visitor is searched and Jordan is a visitor, you may infer Jordan is searched. A guess that is merely likely ("the unit was probably short-staffed") is not a valid inference because the passage does not force it. The test for a legitimate inference is: could the conclusion be false while every sentence in the passage stays true? If yes, it is a guess, not an inference.

A worked example

Passage: "During recreation, officers supervise the yard from fixed posts and conduct headcounts every thirty minutes. The directive does not address inclement weather."

Question: Based on the passage, what should officers do during a sudden thunderstorm?

Work it: The passage covers fixed posts and thirty-minute counts but explicitly does not address weather. A strong reader notices the gap and refuses to fill it. The best answer is the one acknowledging the passage gives no weather guidance (in practice an officer would follow a separate inclement-weather policy or supervisor direction, but that is outside this passage).

Distractors will offer confident, sensible weather responses — "return everyone indoors immediately," "continue recreation," "suspend counts" — each of which sounds reasonable and each of which the passage does not support. The obviousness of those choices is exactly the bait.

A quick self-check before you commit:

1. Can I underline the words that prove this answer? If not, stop.
2. Am I using "usually," "obviously," or "in real life" to justify it? Red flag.
3. Does the passage actually address the question's topic, or is it silent?
4. Is my inference forced by the text, or merely likely?
5. Does the answer add authority, urgency, or facts the passage never gave?

Why obvious answers are suspect

Test writers build distractors from the most plausible outside assumptions, because those are what most candidates reach for. That makes the answer that feels obvious a warning sign rather than a green light. When a choice seems too easy and matches your gut more than the text, slow down and demand the supporting words. The passage is the only authority inside a reading item; treat everything you brought with you — experience, instinct, common sense — as inadmissible unless the words on the page invite it in.

A useful drill is to articulate, for each answer you keep, the exact sentence that licenses it, and for each answer you reject, the assumption it smuggles in. "I'm choosing this because the passage says officers conduct counts every thirty minutes" is a textual justification; "I'm choosing this because that's what any reasonable officer would do" is an assumption you should distrust. Over time this habit becomes automatic and fast — you stop being tempted by sensible-sounding distractors because you have trained yourself to ask for the receipts.

On a job where directives, post orders, and court-tested policies govern conduct, that same discipline keeps you out of trouble: act on the document in front of you, escalate when it is silent, and never substitute your own assumption for a written rule.
