Stimulus

Student: My university recently enacted new penalties for drinking alcohol in on-campus student housing. But the university has attempted to curb on-campus drinking many times in the past, and these attempts have never been bound to be just as ineffective.

What this question is testing

Flaw

Your task

Describe the reasoning error the argument actually commits.

Common trap

Answers that name a real logical flaw the argument doesn't actually make.

Winning move

Articulate the gap in the reasoning yourself, then match it to the choice that describes that gap.

The question
1.

The reasoning in the student's argument is most vulnerable to criticism on the grounds

Answer choices, explained

  1. Never a Flaw1% picked this

    fails to specify what new penalties the university enacted for drinking alcohol in

    If we say that an author fails to establish X, does not state X, neglects to specify X then we're complaining that the author "should have said X. He was implicitly assuming X, but he needs to say it out loud for his argument to work". For example: "Paul applied to Notre Dame. Thus, Paul must want to go to a great dental school." Correct answer: (A) fails to specify that Notre Dame is a great dental school Incorrect answer: (A) fails to specify that Notre Dame's school ranking among dental schools This latter answer is too specific / too quantitative. That's never the correct answer on Flaw. We're never complaining that we lack a specific number / measurement / definition. Here, being told the specific penalties the school has in mind wouldn't actually have any logical force, because ultimately what we care about is whether the penalties this time around are different from the previous failed attempts. This could be a correct answer fails to consider that the new penalties enacted are much harsher than those of previous attempts to curb drinking. We care whether and how the penalties are different from before, not what they specifically are.

  2. Not an Objection1% picked this

    overlooks the possibility that many students did not drink alcohol in on-campus housing even before the

    Whenever Flaw answers start with fails to consider / overlooks the possibility we can ask ourselves whether the argument would be hurt by this new idea. Does it hurt this author's argument that "since previous anti-drinking campaigns failed, this new one is also going to fail" if we say, But, Author, did you know that many students on campus don't even drink? Nope, that's not an objection. We all know some drink, some don't. The issue is whether these campaigns can get some of the current drinkers to stop drinking on campus. Since the author was never assuming that everybody on campus drank in the dorms, it can't weaken her argument to say, "You know a bunch of people don't drink in the dorms".

  3. Out of Scope: preferred location1% picked this

    presumes, without providing justification, that students' preferred location for drinking alcohol

    Whenever Flaw answers start with presumes / takes for granted we can ask ourselves whether the argument needed to assume this idea. Does this author need to assume that drinking in the dorm is students' favorite choice? Does it hurt this author's argument if we say, "drinking in the dorm is not their preferred location"? No, that doesn't hurt anything. I drank in the dorms my fair share, even though it wasn't my preferred location. My preferred location would have been at a bar (which I was too young to get into and too broke to afford) or at a sporting event / concert (which I was too broke to afford) or in a desolate field looking at the stars (which wasn't available near where I went to college). So even though drinking in the dorms was my 4th choice, I still did plenty of it. Even if the students at this university would prefer to drink somewhere else, many of them still do drink in the dorms and hence the university is trying yet another scheme to try to shut that down.

  4. Correct97% picked this

    overlooks the possibility that the new penalties are relevantly different from the university's past attempts

    Why this is right

    This says Overlooks the Possibility and it does indeed work as an objection. We can say, "Even though previous attempts failed, these new penalties have a chance of being effective, after all ... the new penalties are importantly different from the previous ones". When an author is assuming that "what was true in the past will be repeated again", we object to that argument by saying, "Past ? Present".

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

  5. Not an Objection: other consequences1% picked this

    fails to consider whether the new penalties will have any other positive consequences besides reducing drinking

    Whenever Flaw answers start with fails to consider / overlooks the possibility we can ask ourselves whether the argument would be hurt by this new idea. Does it hurt this author's argument that "since previous anti-drinking penalties failed, these new penalties are also going to fail to curb on-campus drinking" if we say, But, Author, these penalties will have other positive consequences, even though they won't curb drinking in the dorms. No, that doesn't hurt the author. If she were arguing, "We shouldn't impose these new penalties", then we would be able to do this whole pros and cons discussion that even if this plan doesn't help the drinking problem it has other advantages that make it worthwhile. But this isn't should. This conclusion is speaking narrowly about whether the plan will or will not have one specific effect: curbing on-campus drinking. Any other effects it has are irrelevant to whether the author's conclusion is right or wrong.
