Stimulus

Professor: It has been argued that all judges should be elected rather than appointed to their positions. But this is a bad idea. If judges ran for election, they would have to raise campaign funds. Thus, they would be likely to accept campaign contributions from special interests. It is well-known that such be expected that they would produce similar conflicts of interest for judges.

What this question is testing

Principle-Strengthen

Your task

Break the argument into its conclusion and evidence, then do exactly what the question stem asks with that structure.

Common trap

Answers that sound relevant to the topic but don't connect to the argument's actual reasoning.

Winning move

Predict what a right answer must do, then test each choice against the conclusion-evidence gap.

The question

Which one of the following principles, if valid, would most help to justify

Answer choices

  1. Bad Premise Match6% picked this

    If politicians should avoid conflicts of interest, then judges should avoid conflicts of

    If this answer simply said "judges should avoid conflicts of interest", then knowing what we were told about electing judges, this would strengthen the idea that judges shouldn't be elected. But this answer is conditional, so it only has any power if you trigger it. Can we trigger it? Were we told that politicians should avoid conflicts of interest? Nope. So this answer does nothing for us.

  2. Unrelated to Goal2% picked this

    Special interests should not make offers of campaign contributions to those running

    This is a principle that would help us say what special interests should / shouldn't do. We're looking for a principle that would help us say whether judges should / shouldn't be elected. So this is nowhere close to the right type of wording.

  3. Bad Conclusion Match16% picked this

    Judges should be appointed to their positions only if doing so ensures that they will usually be able

    Because "only if" signifies the right side idea, this is saying should → appointment ensures be usually no conflicts appointed of interest If we contrapose this, then we have a rule that says, if there usually is conflict of interest, then judges should not be appointed. That's a bad match for our conclusion, which is "judges should not be elected". The conclusion actually implies we should stick with our current system of appointing judges, so this answer would only help us to disprove the conclusion.

  4. Bad Conclusion Match2% picked this

    If judges should be appointed, then it is likely that there are other public offices that should be changed

    This, structurally, is useless for the same reason (C) was. It's not a rule that helps us to prove "judges should not be elected". Bizarrely, it's another rule that allows you to prove "judges should not be appointed", which is the opposite of our conclusion. Remember, that principles (or conditionals) only allow you to prove/conclude the idea to the right of the arrow. This rule is written should be appointed → xyz So we would contrapose it to see its resemblance to the conclusion, ~xyz → should not be appointed

  5. Correct74% picked this

    No public office for which election campaigning would be likely to produce conflicts of interest should be changed from an

    Why this is right

    No A's are B = A → ~B So this rule reads like this: Public office for should not be which election changed from campaigning would → an appointed office be likely to produce to an elected office conflicts of interest Is judging a public office for which campaigning would be likely to produce conflicts of interest? Yes. Were they to have to campaign, it is likely that they would accept campaign contributions, which is well-known to lead to conflicts of interest. Since we can trigger this rule, we can say that "judges should not be changed from appointed to elected officers", which is a great match for our Conclusion.

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