Inflation of Conflict

Description: Reasoning that because authorities cannot agree precisely on an issue, no conclusions can be reached at all, and minimizing the credibility of the authorities, as a result.  This is a form of black and white thinking -- either we know the exact truth, or we know nothing at all. 

Logical Form:

Authority A disagrees with authority B on issue X.

Therefore, we can say nothing meaningful about issue X.

Example #1:

My mom says that I should study for at least 2 hours each night, and my dad says just a half hour should be fine.  Neither one of them knows what they are talking about, so I should just skip studying altogether.

Explanation: A disagreement among experts does not mean that both are wrong, the answer is a compromise, or that there is no answer to be known; it simply means that there is disagreement -- that is all we can infer.

Example #2:

Scientists cannot agree on the age of the universe.  Some say it is 13.7 billion years old, some say it is only about 13 billion years old.  That’s a difference of almost a billion years!  It should be clear that because there is so much disagreement, then the 6000-year-old universe should be carefully considered, as well.

Explanation: Scientists who “disagree” with the estimated age of the universe do so primarily on slightly different interpretations of the same objectively valid dating methods.  The difference is fairly minute in terms of percentage.  Suggesting 6000 years is valid is one thing, but doing so based on the difference in interpretation from mainstream science is completely fallacious.  The differences have no bearing on the truth claim of the argument (the actual age).

Exception: When the difference in professional disagreement is critical, it should be carefully examined. For example, if two doctors were debating on what medicine to give a patient, and both were claiming that the other medicine would kill the patient.
