Modes of persuasion: Ethos

While most people can spot when a speaker is delivering a logical or emotional argument, ethos is a more complex and subtle thing to determine. The term can be translated as “authority,” although this does not necessarily mean the authority a speaker brings to the subject due to his or her level of expertise or experience.

While such authority can be a component of ethos, an appeal to authority (including one’s own) can also be considered a fallacy, especially if the person claiming authority has not earned this right (or is trying to use his or her authority on one subject to establish credibility in another subject outside their domain of expertise).

If we think of ethos as unit of credibility or character, a speaker can establish credibility by speaking exceedingly well and convincingly. And (as discussed in the podcast), if someone presents an argument based on sound logic, appeals to good vs. bad emotion, and strikes the right balance between logos and pathos, they are well on their way to being awarded ethos by the audience.

But another critical component of ethos is the connection one makes to that audience, whether or not such a connection is directly related to a subject being debated. If a speaker can demonstrate that they are sympathetic with the audience and its concerns, by using language the audience can relate to or establishing some other form of “kinship,” that can be an important (sometimes the most important) means of generating ethos.

When Aristotle was formulating the three modes of persuasion, political speech was primarily that: speech, given before live audiences in popular assemblies or the courts. But in our modern world, we don’t tend to get so much face time with the people who are trying to convince us to vote for them.

Rather, we are forced to create a composite of a candidate based on inputs and information coming from different sources (the news media, breakdowns of a candidate’s personal and political history, campaign ads created by them as well as directed against them). In fact, even when we have celebrated a particular candidate’s rhetoric skill (as we did President Obama during the 2008 election), our evaluation was based more on his ability to enthuse extremely large audiences rather than an understanding of the logos, pathos and ethos behind any one of his speeches.

Ethos is tricky with regard to partisan politics since most of us tend to reward it automatically to the person we were planning on voting for anyway (and similarly denying it to his opponents) regardless of what either candidate says and does.

But this understandable partisan tendency can lead us to misjudgments and surprise, especially if we fail to understand the ethos appeal a candidate might have to people with whom we might disagree.

Earlier, we talked about the Principle of Charity and how it can be used to help us overcome biases that make us vulnerable to errors and narrow thinking. And being a bit more generous in how we reward ethos might be the best starting point to living by this principle.

Modes of persuasion: Pathos

As appealing as it might be to base all of our decisions on cold, hard logos, logic alone suffers from two significant shortcomings.

First, the structure of logic works, regardless of the “facts” it is applied to. For example, IF all unicorns are magical creatures AND Gerry is a unicorn, then the statement “Gerry is a magical creature” is logically true, even if unicorns, magical creatures (or Gerry, for that matter) do not exist.

More significant for those looking for practical ways to apply critical thinking to important problems (such as choosing a President) logic cannot necessarily break a tie between two arguments of equal logical strength. Building on a simple example from the last blog post, there might be a perfectly valid and logical argument why a school band should spend its money on new uniforms (because they will provide benefit for many years) and an equally sound argument why that same money should be spent to play at the Rose Bowl (since it raises the profile of the band and will help recruit new members).

Given that most of the political debates we have (or should have) are based on choosing between equally valid (and often equally good or bad) choices, something other than logic must be used to help us make a choice. Enter human emotion.

Now arguments based on emotion (i.e., pathos) tend to make us uneasy since emotion is seen as non-rational and those who try to argue with it can come off as manipulative. And there is no question that pathos can and has been used to manipulate people throughout history.

But the criticism of pathos being destructive assumes that all emotions are equal, which they clearly are not. Appealing to fear, greed, hate, envy and guilt for example, represent an appeal to bad emotions (or, as I like to think of them, “emotions of the gut”) while an appeal to courage, generosity, love and sympathy appeal to good emotions (or “emotions of the heart”).

So one way to determine if pathos is being used cynically or constructively is to analyze whether the emotions we are being asked to take into account when evaluating an argument (such as a campaign speech) are reaching to our gut vs. our heart.

The other factor to keep in mind is that strong arguments that leverage emotion (good or bad) should not rely exclusively on emotional appeals. In fact, one sure sign of demagoguery is the demagogue’s exclusive or over-reliance on pathos vs. finding just the right combination of logos and pathos to drive the argument forward.

Given that every political debate has an emotional component, we should not become cynical if a political speaker makes use of powerful pathos-based rhetorical techniques. And we should be particularly careful not to fall into the trap of deciding that the emotional content of speeches made by candidates we support are inspiring while those made by their opponents are creepy and manipulative.

Rather, we should judge political speech (made at a campaign stop or TV ad) based on whether the speaker is appealing to the gut vs. the heart, and how well they get the balance right between logos and pathos. And if they get this tricky combination right, they will be rewarded with the highly valuable third component of rhetoric: ethos, the subject of the next posting.

Modes of Persuasion: Logos

This week’s podcast talked about Aristotle’s three modest of persuasion, which includes:

Logos – An appeal to logic

Pathos – The appeal to emotion

Ethos – A somewhat more complex concept relating to the authority and credibility of the speaker

Today, we’ll take a look at logos and see how it can be use by political candidates trying to get our attention and persuade us to do this or that, and by voters to determine the quality of those political arguments.

Despite the fact that classical logic is not automatically part of everyone’s high school or college education any longer, logic is still an enormously popular and ingrained subject in scientific and technical areas. Anyone performing computer programming (from kids playing Scratch to skilled developers working with advanced programming languages) are essentially wrestling with logical problems built on the premise that thought and action can be boiled down to symbols that can be manipulated and tested for accuracy.

In political discourse, our innate passion for consistency can be seen as our natural desire to reject any argument that boils down to the simple logical statement: “A equals NOT A” (a contradiction that automatically disqualifies an argument as having insufficient logos).

Now when we deal with complex issues (such as budget priorities, national defense, social issues and the like), it can sometimes seem like these matters are far too complicated to transform into simple IF-THEN statements. In fact, one of the great frustrations of technically minded men and women (such as scientists and engineers) with politics is that political discourse seems to defy the type of neat categorization they see in their professional life.

But all arguments – even the most complex – can be translated into smaller units, each of which can be tested for logical soundness. For example, a particular spending program (whether designed to help the poor or defend the nation) implies premises (that there exists a category of people needing a certain service or a threat that needs countering by a specific weapon system), which can be identified and analyzed. And once those premises have been studied, we can review the chain of logic between those premises and the conclusions drawn from them.

These logical chains can go in more than one direction. For example, there may be a compelling logic that a spending program will be effective, but an equally compelling logic that demonstrates it will not be cost-effective (which would imply the need to search for other alternatives).

In fact, the greatest problem associated with basing our political discourse and analysis on logos has nothing to do with the inability of logic to help us separate good from bad policies. Rather, it is the fact that logic does not provide us with enough information to decide between competing goods.

Even if we look at a simple, localized political issue (such as whether or not to buy school band uniforms this year vs. use that money to pay for a trip to perform in the Rose Bowl), we are likely to end up with equally compelling arguments on either side of equivalent logical soundness. In fact, most (if not all) of the political arguments worth having are not between the bad and illogical vs. the good and logical, but between two equally good and equally logical alternatives.

For those decisions, we need some additional information (or persuasion) to make a decision. And one of the things we can turn to are our emotions. So tune in next time for a discussion of pathos.

Critical Voter - Podcast 3 - Modes of Persuasion

This week’s podcast covers Aristotle’s three modes of persuasion: logos, pathos and ethos.

Every argument, including every campaign speech, commercial or debate performance, will include attempts to persuade the audience using logic (logos), emotion (pathos) and authority (ethos), which means that an understanding of these three concepts will be central to our ability to think critically about the US election.

While these three elements were created in the past (in ancient Athens) and are relevant in the present (during this year’s election campaign), they also have something to say about the future. This includes the fictional future of Star Trek where we can see logos, pathos and ethos play out in the themes and characters of one of television’s most popular science fiction shows.

References made during this podcast include:

Links to suggested sources for further study of Aristotle and ancient philosophy can be found on the Resources page

Educational material associated with this week’s podcast include:

Critical Voter - Modes of Persuasion - Quiz

Critical Voter - Modes of Persuasion - Lesson Plan

Questions on Questions

Some of you may be wondering what you should do with those quizzes that I’ll be including in the educational resources associated with each Critical Voter podcast.

Like the Lesson Plan that is published each week along with the podcast, the quiz is meant to be a resource for educators interested in integrating the Critical Voter curriculum (in whole or in part) into their classroom.

While the lesson plans, blog entries and other materials on the Critical Voter site can be useful to teachers, the podcast really provides the “meat” of Critical Voter’s educational content.

Because the length of each podcast hovers around 30 minutes, I recognize that some teachers may assign the podcast as a homework assignment and need a way to confirm that students have listened to that program in its entirety. And so, I decided to create a short quiz that goes along with each podcast and include it in the educational resources released each week.

I have a background in professional test development, and designed the quizzes to be fast and easy for someone who has listened to the podcast, but challenging for someone who has not absorbed this material. In other words, they contain no complex or “trick” questions, just basic multiple-choice questions that someone who listened to the podcast should be able to answer easily.

I’m assuming teachers using the Critical Voter curriculum will become podcast listeners and further assuming that they will be able to generate their own answer key by taking the quiz themselves after listening to the podcast. (Although if you’re a teacher and want to receive or confirm the right answers each week, just drop me a note via the Contact form.)

I’m exploring additional options, including adding automated quizzing to the site and creating a weekly mailing list just for instructors which can include answers to this week’s quiz. But until I can figure out a secure option (and determine if such features are necessary), please feel free to use the existing quizzes in their current PDF format and contact me if you’ve got any further questions.

Resource: Critical Thinker Academy

I made mention a few times to Kevin deLaplante’s Critical Thinker Academy in this week’s podcast, and the Academy site is linked on both the blogroll and resources pages of this site.

But I wanted to give an official shout-out to this resource which includes both a paid set of formal lessons and a wealth of free tutorials and podcasts (available on iTunes, YouTube and elsewhere).

The Academy is in transition right now as its owner prepares to make a full time commitment to expanding the content on the site to a comprehensive suite of critical thinking lessons. But even the free resources available on the Academy can make an invaluable contribution to your understanding of key critical thinking subjects, especially with regard to the role played by cognitive studies in understanding how we think and reason.

Cognitive Challenge

I linked to this example of a cognitive illusion in the educational resources section of this week’s podcast. But this one is so much fun that I wanted to also make it available as a separate blog post.

The only hint I’ll give you is that the answer to the question is greater than 10.

Good luck!

 

Think Fast!

Throughout this week’s podcast, I made multiple references to Daniel Kahneman’s Thinking Fast and Slow, a recent best seller that describes the author’s work with the late Amos Tversky that revolutionized the way we think of ourselves and the way our brains work.

The heart of Kahneman and Tversky’s theory is that our brains are separated into two “processes.” Our “fast process” rapidly takes in information from our senses and makes sense of it by creating associations and working those associations into stories. And a second “slow process” is slower and more deliberative but when it is engaged (which isn’t often, since it is rather lazy) it can overwhelm our fast process as it processes information in ways the fast process cannot do.

This model helps explain a number of observable phenomena such as our susceptibility to visual and cognitive illusions. It also helps explain pan-human tendencies towards certain types of cognitive biases, notably confirmation bias which makes us readily accept information that already conforms to our beliefs, but treats information that contradicts or confounds those beliefs with suspicion.

After all, if our fast associative fast processor uses stories to categorize and understand information coming at us from all directions, what makes more sense than to create a story that plays up our preferences and plays down or rejects our dislikes?

There is a lot more to Kahneman and Tversky’s work beyond what I described in this week’s podcast. And while it’s not required reading to follow along with the rest of the lessons we’ll be covering in Critical Voter, Fast and Slow is a great read and surprisingly accessible, given the complexity of the theories the author is discussing. So grab and enjoy a copy if you’re inspired to find out why we human beings think the way we do.

The Principle of Charity

In this week’s podcast, I talked about recognizing our own biases while also trying to recognize which biases are relevant to a particular issue and which are not.

Complex challenges such as navigating the treacherous waters of bias can often be mitigated through the application of a bit of “folk wisdom,” vs. ruthlessly logical proofs. And philosophy offers us something that can serve this role in the “Principle of Charity.”

This “Principle of Charity” requires participants in debate to extend certain “benefits of the doubt” to one another. One manifestation of this principle would be to consider and engage with the strongest interpretation of an opponent’s arguments. As I mentioned in the podcast, the philosopher Nigel Warburton uses this terrific example to illustrate the concept:

“… in a debate about animal welfare, a speaker might state that all animals should be given equal rights. One response to this would be that that would be absurd, because it would be nonsensical, for example, to give giraffes the right to vote and own property since they would not understand either concept. A more charitable approach would be to interpret the claim ‘All animals should have equal rights’ as being a shorthand for ‘All animals should have equal rights of protectionfrom harm’ and then to address that.”

If we were to apply the Principle of Charity to this year’s presidential contests, the first thing we would have to do would be to take the candidates at their word that their primary motivation for running for President is their love for America and their desire to contribute to improving it. While it is possible that one or both of next year’s Presidential candidates are Manchurian in nature, secretly planning to turn the country over to its enemies or transform us into a plutocracy, we are likely to get a better understanding of the candidates and the issues if we start with the charitable (and, likely, more accurate) position that the primary motivations for these candidates are positive.

This principle is similar to other concepts, such as the Golden Rule or Aristotle’s Golden Mean in preventing our own biases from overwhelming our judgment through a healthy application of balance and open mindedness.

To take one small example, last year, we had a brief political dustup in my home state between the two likely candidates for Senator next year: one male, one female. In this instance, one of the candidates had posed for fashion photos in their youth which led the other candidate to joke that they “didn’t need to take [their] cloths off to get through college,” to which the other candidate replied “Thank God.”

Now this could have been interpreted as light political banter between rivals (hardly Churchillian in its wit, but still humorous). But instead it became the subject of accusation and counter-accusation of sexism vs. snobbery. And if you knew which candidate belonged to which gender and party, you can pretty much guess on which side most partisans landed in this debate.

But what if you didn’t know who was who? If you find yourself withholding your outrage until you find out which party each quipper belonged to, more than likely this is not a genuine issue but rather a matter of political theatrics which provides little insight into anything other than our own biases. How much simpler to simply apply the Principle of Charity and assume this exchange to be nothing more than some light hearted back-and-forthing between rivals that pretty much means nothing, then moving onto matters more worthy of discussion and debate.

Critical Thinking and Bias

The reason bias is such a frequent topic of conversation in both critical thinking and politics is because it is an issue all of us grasp intuitively. Unlike other critical-thinking tools which need to be learned, bias is something that so permeates and surrounds us that most of us simply “know it when we see it” (especially when we see it in others).

But, as I mentioned during this week’s podcast, bias is not something we should be ashamed of since many biases – called cognitive biases – are part of the human condition. In fact, there are over 100 such cognitive biases that we can all fall prey to simply because of the way our brains are wired.

The most significant cognitive bias that impacts how we think about politics is confirmation bias, the tendency to seek out and believe information that conforms to existing pre-conceptions and dismiss or reject information that challenges these closely held beliefs.

As Kevin deLaplante describes in this podcast (and I highly recommend you listen to his entire series), systems such as science have developed tools and processes to try to overcome confirmation bias (via experiments such as double-blind tests). But politics has no similar formal filters, meaning that most of us still gravitate towards and accept those newspapers, radio and TV shows, blogs and other online sources that tell us what we want to hear, while dismissing comparable media sources that we don’t agree with as horrifically and embarrassingly biased.

This is a pity since both bias itself and inappropriate ways of trying to compensate for bias can lead to error.

Most people, for example, simply embrace their biases (even as they construct elaborate mechanisms to convince themselves that both they and their news sources are “fair and balanced”). But in addition to closing the mind, this combination of bias and self-deception leaves one vulnerable to (among other negative consequences) disappointment and surprise. (Think of someone who dismisses sex scandal allegations against a favored candidate because charges first appear in a news source beloved by “the other side,” only to watch their candidate – and their own hopes - implode when those charges turn out to be true.)

Another common mistake is to assume that since everyone is biased (which we all are, at least with regard to hard-wired human cognitive biases) that no one is in a position to either claim truth or judge others. But assuming that we are made up of nothing but our biases (either cognitive biases, or biases that result from our membership in a particular age, gender or demographic group) can paralyze us, preventing us from thinking of ourselves as free, independent and critical thinkers.

Is there a solution? Well, there is a rule thumb that can use to help guide us through this quagmire: The Principle of Charity. (Stay tuned…)
