Fallacies – 3

Well the primary race starts today, as does the countdown to when we’ll be applying some of the critical thinking tools we’ve been reviewing to real, live candidates.  But while we still have the luxury to work with abstractions, let’s finish up this discussion of fallacies with a review of best practices regarding how to avoid falling for them.

All three of the major categories of fallacies that were highlighted as likely to come at us over the coming months (including fallacious Argumentsfrom Authority, Emotion or Moderation) have something in common: they all take advantage of our better natures which would normally be respectful of authority, open to moving appeals to the heart, and ready to avoid extremes.  Fortunately, this points to an effective way to avoid falling into rhetorical traps: by letting our better natures prevail.

Take Arguments from Authority, for example.  In a sense, the best way to avoid falling for this type of fallacious argument is to follow the advice on that old bumper sticker to “Question Authority.”  But by this I don’t mean we should be mindlessly skeptical of all authority figures.  Rather, we should be respectful of people with high levels of intelligence and expertise, but not defer to them in all situations.

For starters, if someone is giving advice outside their field of study, they should be respected no less (and certainly no more) than any other smart person talking outside of their discipline.  It is only if they demand to be taken seriously as an authority on a subject about which they have no special knowledge (even if they are held as extremely prominent within that other field) that we should smell a potential rat. 

And even people speaking within their field should never be given an absolutely free ride.  If an expert is at odds with the consensus of his or her profession, they could either be a far-seeing sage or a quack.  In either case, additional evidence is required by them, as is additional analysis by us. 

In fact, any evidence we receive from experts should not be taken as received wisdom, at least not by those who want to be take critical thinking seriously.  Yes, there are some subjects (such as quantum mechanics) where most of us are forced to take an expert’s word that certain non-intuitive and unobservable phenomena can be explained only by complex theories that take years to understand.  But how many political issues that we face during an election cycle are so complex that we cannot bring our own ability to research, learn and think to an evaluation that can include learning from (without unquestioningly deferring to) multiple experts on different sides of the same political issue?

There are similar common sense solutions to the other two fallacies on the table. As was already discussed, Arguments from Emotion are on shaky ground if they appeal to things like fear, greed and hate and if they appeal to emotion only (rather than finding the right balance of logos and pathos to earn ethos on behalf of the speaker).  And if the extremes someone is trying to position themselves between to convince us that they are sane and moderate bear no resemblance to actual, practical political options, chances are someone is trying to manipulate you.

The most difficult part of all these reasonable solutions is that they must be applied across the board: to candidates we support as much as those we oppose.  Otherwise, we end up looking like the Internet debaters I remember from the old Wild West days of Usenet who periodically published (OK, cut and pasted) long lists of fallacies, only to apply them solely to the arguments of their opponents (never to themselves).

The use of a critical thinking vocabulary as a political weapon can itself be considered a fallacy (perhaps a “Fallacy Fallacy” if applied to my Usenet example), one in which the tools of critical thinking are simply used to give a partisan argument unearned weight.  As we get closer to Election Day and passions begin to boil, it will become increasingly difficult to pass judgment on our preferred candidate when they appeal fallaciously to authority, emotion or moderation (or utilize some other rhetorical trick that we know to be problematical).  But being honest with ourselves is how we can keep our preferred candidates honest with us as well. 

Most importantly, such honesty is the only way we can keep our own minds truly independent and ourselves truly free.
