UMAT Critical Thinking 1 — Questions and Answers
Question 1: In a UMAT problem-solving question, you are told: 'All registered nurses have completed clinical training. Jane has completed clinical training.' What can you validly conclude?
- Jane is a registered nurse
- Jane may or may not be a registered nurse (Correct answer)
- Jane is definitely not a registered nurse
- Jane is a doctor
Correct answer: Jane may or may not be a registered nurse
Completing clinical training is a necessary condition for being a registered nurse but not sufficient — others may also complete it, so Jane's status cannot be confirmed.
Question 2: A researcher claims that eating breakfast causes better academic performance because students who eat breakfast score higher on tests. What is the main flaw in this reasoning?
- The sample size is too large
- Correlation is being mistaken for causation (Correct answer)
- The researcher used the wrong statistical test
- Academic performance cannot be measured
Correct answer: Correlation is being mistaken for causation
Observing a correlation between two variables does not establish that one causes the other; confounding factors may explain both.
Question 3: Which of the following is an example of a deductive argument?
- Most students who study pass; therefore some students will pass
- All mammals are warm-blooded; whales are mammals; therefore whales are warm-blooded (Correct answer)
- It has rained the last three Mondays, so it will probably rain next Monday
- Studies suggest exercise improves mood, so exercise might help this patient
Correct answer: All mammals are warm-blooded; whales are mammals; therefore whales are warm-blooded
A deductive argument moves from general premises to a specific conclusion that must be true if the premises are true, as in the classic syllogism format.
Question 4: A clinical study shows a new drug reduces symptoms in 60% of patients compared to 40% on placebo. A critic points out both groups improved. The critic is raising the issue of:
- Sample bias
- The placebo effect complicating interpretation of results (Correct answer)
- Statistical significance being too high
- Lack of a control group
Correct answer: The placebo effect complicating interpretation of results
When placebo groups also improve, it complicates causal attribution because the improvement cannot be entirely attributed to the drug itself.
Question 5: Which of the following best defines 'ad hominem' reasoning, which the UMAT tests as a logical fallacy?
- Arguing from authority without evidence
- Attacking the person making an argument rather than the argument itself (Correct answer)
- Making an argument based on popular opinion
- Presenting a false choice between two options
Correct answer: Attacking the person making an argument rather than the argument itself
Ad hominem is a logical fallacy where someone attacks the character or credibility of the person making an argument instead of engaging with the argument itself.
Question 6: In evaluating evidence for a UMAT critical thinking question, which source of information is generally most reliable?
- A single anecdotal report from a respected person
- A peer-reviewed meta-analysis of multiple randomized controlled trials (Correct answer)
- A widely shared social media post about health outcomes
- An opinion piece in a popular magazine
Correct answer: A peer-reviewed meta-analysis of multiple randomized controlled trials
Peer-reviewed meta-analyses synthesize multiple controlled studies and undergo rigorous expert review, placing them at the top of the evidence hierarchy.
