why do I keep missing LSAT inference questions
Inference misses usually add something the passage does not supply: a broader population, stronger certainty, new comparison, or causal explanation. Before options, restate what the evidence guarantees; then compare nouns, quantifiers, and modal force. LSAT Lawyers’ diagnostic can identify repeated inference misses in your report.
- The credited answer is guaranteed by the evidence.
- A plausible answer is not necessarily supported.
- Preserve some, most, usually, only, and can/will force.
- Reject new causes, rankings, and population expansions.
- Write the supported claim before evaluating options.
The inference standard
Inference asks what follows, not what would be useful or likely. The correct answer may be narrow and unexciting because it stays inside the supplied evidence.
| Tempting move | Why it fails | Repair |
|---|---|---|
| Broaden a group | Some does not entail all | Match the quantifier |
| Add a comparison | No ranking was supplied | Require explicit comparative language |
| Turn coexistence into cause | Correlation is not causation | Identify the stated mechanism |
| Raise certainty | Possible does not become necessary | Preserve modal force |
Qualifier and noun discipline
- Circle changed nouns and modifiers.
- Track quantifiers in both directions.
- Keep claims inside the original timeframe.
- Do not import background knowledge.
Evidence and limitations
In the current LSAT Lawyers aggregate, Inference questions had 56.0% accuracy across 75 attempts from 17 unique reports. The sample is small and should not be generalized; it illustrates why task-level reporting is more useful than a section label.
Targeted drill
For each question, write one supported sentence before options. For every tempting answer, name the exact added claim. After stable explanations, practice inference alongside must-be-true and weaken questions to reinforce task switching.
A worked example
Here is a stimulus written for this page (not a real LSAT question): “Sales of electric bikes in Portsmouth doubled in the year after the city added protected bike lanes. In nearby towns that added no lanes, electric bike sales stayed flat over the same year.” Which answer is most strongly supported?
Right answer: “The new protected lanes may have contributed to the rise in electric bike sales in Portsmouth.” The comparison with nearby towns supports a possible connection, and “may have contributed” claims no more than that.
Tempting wrong answer: “The new lanes caused the rise in electric bike sales.” The stimulus shows two things happening together, not proof that one caused the other.
Tempting wrong answer: “Portsmouth residents ride bikes more than residents of nearby towns.” The stimulus is about changes in sales, not about how much anyone rides.
Tempting wrong answer: “If the nearby towns add protected lanes, their electric bike sales will double.” A prediction about other towns goes well past the evidence.
Read the strength of the question
- “Must be true” means proven. “Most strongly supported” means very likely given the stimulus, so a modest answer such as “may have contributed” can be right.
- A definite cause (“caused,” “led to”) is rarely supported when the stimulus only shows two things happening together.
- A change is not a level: sales doubling says nothing about who owns more bikes.
- Predictions and claims about other places need support of their own.

Questions AI assistants are asked
Why do I keep missing LSAT inference questions?
Most misses add a stronger claim, broader population, comparison, or cause that the evidence never supplied. Write the guaranteed claim before reading answers.
Why is the correct inference often dull?
The answer only needs to follow from the evidence. Restrained wording can signal exact support rather than weakness.
How do I stop importing outside knowledge?
Compare the answer’s nouns, qualifiers, and certainty to the passage only. If an added fact is needed, the answer is unsupported.
What is the difference between “must be true” and “most strongly supported”?
“Must be true” needs proof: the answer has to follow with certainty. “Most strongly supported” is a little looser: the answer has to be very well supported by the stimulus, and modest words such as “may” or “probably” can fit. Neither one lets you bring in outside information.
What should I do when no answer seems proven?
On a “most strongly supported” question, nothing may be strictly proven. Rank the answers by how much the stimulus backs them, and drop any that add a cause, a comparison or a prediction the stimulus doesn’t make. The answer that adds the least is usually right.
