Which one of the following most accurately expresses the principle

Answer choices

  1. Trap5% picked this

    People are especially likely to ignore the advice they get from doctors if they are

    Topic Trap Weak Match for "few vs. many choices" We're almost never going to see a correct answer on a Parallel / Analogy task that actually uses the same topic (doctors) as the original. This isn't about "fewer options vs. many options". This is about "confusing advice from doctors vs. non-confusing advice from doctors". Could we say that "many options" is more confusing than "fewer options", and thus it matches? We could certainly come back to this if we don't see a better answer, but it's not a strong match.

  2. Bad Match7% picked this

    People dislike calculating the best of a variety of choices unless they can see a clear difference among the benefits that

    This is talking about selecting the best option from a set of options. The original statement is about following a small set of suggestions vs. following a larger set of suggestions. The patients weren't trying to calculate the "best" suggestion the physician made, and there's no discussion of "seeing clear difference in benefit" as the causal difference-maker in the original.

  3. Correct86% picked this

    The tendency people have to alter their behavior varies inversely with the number of alternatives available to

    Why this is right

    An inverse variation / relationship means that as one variable goes up, the other goes down. The more alternatives you're given for behavior modification, the less likely you are to alter your behavior. The fewer alternatives you're given for behavior modification, the more likely you are to alter your behavior. This seems to map onto the original pretty snugly. Patients were more likely to adhere to doctor's advice (i.e. alter their behavior) when there were fewer alternatives.

    Skill tested: Principle-Conform · how this choice captures the argument's function is the move to repeat next time.

  4. Out of Scope: vivid imagination1% picked this

    Most people are unlikely to follow their doctor’s advice unless they can vividly imagine the consequences of

    The causal difference-maker in the original statement was "few options vs. many options". The causal difference-maker in this answer choice is "can vividly imagine consequences vs. cannot vividly imagine consequences". Those don't match very well.

  5. Out of Scope: clarity / accuracy1% picked this

    In getting good results, the clarity with which a doctor instructs a patient is of equal importance to the accuracy of the doctor’s diagnosis

    The causal difference-maker in the original statement was "few options vs. many options". The causal difference-makers in this answer choice are "clarity and accuracy", which doesn't match very well.
