Pediatrician: Swollen tonsils give rise to breathing problems during sleep, and the surgical removal of children's swollen tonsils has been shown to alleviate sleep disturbances.

Conclusion

Removing tonsils before swelling will ensure that children don't experience any breathing problems during sleep.

Evidence

Swollen tonsils give rise to breathing problems, and surgically removing swollen tonsils can alleviate sleep disturbances.

Evaluate

This conclusion is comin' in hot!

It's promising us that if we remove a kid's tonsils before they start to swell, it guarantees that kids will not experience any breathing problems during sleep.

Really? They'll never have any breathing problems? - what if they have asthma? - what if they have sleep apnea? - what if they have COVID / flu / cold / congestion? - what if they cry themselves to sleep headfirst in a pillow (just me?)

Goal

If we were trying to describe this in formal terms, we might say that the author thinks . Conversationally, we can object as we just did by saying, .

The pediatrician's argument is most vulnerable to the criticism that it

  1. relies on an inappropriate appeal

    Wrong Flaw

    This is the famous Inappropriate Appeal flaw, but this argument didn't rely on a dubious expert.

  2. relies on an assumption that

    Wrong Flaw

    This describes the famous Circular Reasoning flaw, in which the evidence restates the conclusion or assumes the conclusion is true. But we're not critiquing this argument by saying that the author's evidence involves repeating or already-believing the conclusion. We're saying the author only managed to prove that preemptively removing tonsils would make children less likely to experience breathing problems during sleep; she didn't prove that kids would never have breathing problems. The author relies on the assumption that "swollen tonsils are the only possible source of breathing problems", and that does not match her conclusion. (tantamount = essentially the same as) I could say, "Asking Jill to move in with me was tantamount to proposing that she marry me."

  3. infers from the fact that

    Wrong Flaw

    This refers to the famous Intent vs. Result flaw, in which authors conflate whether or not an action was intended to do X with whether or not the action had the consequence of doing X. We definitely weren't complaining about that kind of switch.

  4. fails to consider the possibility

    Not an Objection

    Since this starts with fails to consider, we can ask ourselves, "Would it weaken the argument to tell the author that there may be other reasons to remove tonsils?" Nope. It would only hurt the author if we said, "there may be other medical conditions that give rise to breathing problems at night."

  5. Correct

    fails to consider the possibility

    Why this is right

    Since this starts with fails to consider, we can ask ourselves, "Would it weaken the argument to tell the author that there may be other causes of breathing problems during sleep?" Sure! The author thinks that as soon as we surgically remove the possibility of swollen tonsils, we have guaranteed that kids won't experience any breathing problems during sleep, but we could call that conclusion highly into question by reminding the author, "Yo --- there are other potential causes of breathing problems. Even if little Johnny doesn't have breathing problems from swollen tonsils anymore, he still might have them from his asthma."

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