Metacognition

Next We Can Think About the Way We Think About ThinkingThere's a name for all the studying of our natural thinking styles we've been doing in class lately: metacognition. When we think about the ways we think, we can vastly improve our learning abilities. This is what the Owning Our Ignorance club is about.

I think this is the most valuable concept we're learning all semester. So if you read any links, I hope it's these two:

Wooden-Headed

Here's a little rant on that favorite topic of mine: intellectual honesty. A simple goal of this class is to get us all to recognize what counts as good evidence and what counts as bad evidence for a claim. I think we're getting better at that. But this doesn't guarantee that we'll care about the difference once we figure it out.

Getting us to care is the real goal of this class. We should care about good evidence. We should care about evidence and arguments because they get us closer to the truth. When we judge an argument to be overall good, THE POWER OF LOGIC COMPELS US to believe the conclusion. If we are presented with decent evidence for some claim, but still stubbornly disagree with this claim, we are just being irrational. Worse, we're effectively saying that the truth doesn't matter to us.

This means we should be open-minded. We should be willing to challenge ourselves, and let new evidence change our current beliefs. We should be open to the possibility that we've currently gotten something wrong. This is how comedian Todd Glass puts it:


Here are the first two paragraphs of a great article I read last year on this:

Last week, I jokingly asked a health club acquaintance whether he would change his mind about his choice for president if presented with sufficient facts that contradicted his present beliefs. He responded with utter confidence. "Absolutely not," he said. "No new facts will change my mind because I know that these facts are correct."

I was floored. In his brief rebuttal, he blindly demonstrated overconfidence in his own ideas and the inability to consider how new facts might alter a presently cherished opinion. Worse, he seemed unaware of how irrational his response might appear to others. It's clear, I thought, that carefully constructed arguments and presentation of irrefutable evidence will not change this man's mind.

Ironically, having extreme confidence in oneself is often a sign of ignorance. Remember, in many cases, such stubborn certainty is unwarranted.

Certainty Is a Sign of Ignorance

When Status Quo Isn't Good Enough

Lazy, inert humans:
  • If it already exists, we assume it's good.
  • Our mind works like a computer that depends on cached responses to thoughtlessly complete common patterns.
  • NYU psychologist John Jost does a lot of work on system justification theory: our tendency to unconsciously rationalize the status quo, especially unjust social institutions. Scarily, those of us oppressed by such institutions have a stronger tendency to justify their existence.
  • Jost has a new book on this stuff. Here's a video dialogue about his research:

Wished Pots Never Boil

Here is a hodgepodge of links on some psychological impediments we're discussing recently:
Does Wishful Thinking Work Yet?

No, You're Not

One of my favorite topics is I'M-SPECIAL-ism. Psychological research has repeatedly shown that most Americans overestimate their own abilities. This is one of the biggest hurdles to proper reasoning: the natural tendency to think that we're smarter--or more powerful, or prettier, or whatever--than we really are.

You've probably noticed that one of my favorite blogs is Overcoming Bias. Their mission statement is sublimely anti-I'M-SPECIAL-ist:

"How can we better believe what is true? While it is of course useful to seek and study relevant information, our minds are full of natural tendencies to bias our beliefs via overconfidence, wishful thinking, and so on. Worse, our minds seem to have a natural tendency to convince us that we are aware of and have adequately corrected for such biases, when we have done no such thing."

This may sound insulting, but one of the goals of this class is getting us to recognize that we're not as smart as we think we are. All of us. You. Me! That one. You again. Me again!

(By the way, this is especially true for the actually smart people among us: the more experienced you are, the more overconfident you're likely to become.)

So I hope you'll join the campaign to end I'M-SPECIAL-ism.

The Importance of Being Stochastic

Statistical reasoning is incredibly important. The vast majority of advancements in human knowledge (all sciences, social sciences, medicine, engineering...) is the result of using some kind of math. If I had to recommend one other course that could improve your ability to learn in general, it'd be Statistics.

Anyway, a few links:

Fight the Bias

How can we counteract these cognitive biases we're learning about? The best starting point is to own our fallibility. Awareness of our limits and biases should lead us to lower our degree of confidence in our beliefs. Simply put, we should admit (and sincerely believe) that there's a real chance that we're wrong.

Here are two other big, simple points I think are important:
  1. AKirk & His Straw Bananactively seek out sources that you disagree with. We tend to surround ourselves with like-minded people and consume like-minded media. This hurts our chances of discovering that we've made a mistake. In effect, it puts up a wall of rationalization around our preexisting beliefs to protect them from any countervailing evidence.
  2. When we do check out our opponents, it tends to be the obviously fallacious straw men rather than sophisticated sources that could legitimately challenge our beliefs. But this is bad! We should focus on the best points in the arguments against what you believe. Our opponents' good points are worth more attention than their obviously bad points. Yet we sometimes naturally focus on their mistakes rather than the reasons that hurt our case the most.

The Conspiracy Bug

Here's an article on a 9/11 conspiracy physicist that brings up a number of issues we're discussing in class (specifically appealing to authority and confirmation bias). I've quoted an excerpt of the relevant section on the lone-wolf semi-expert (physicist) versus the overwhelming consensus of more relevant experts (structural engineers):
While there are a handful of Web sites that seek to debunk the claims of Mr. Jones and others in the movement, most mainstream scientists, in fact, have not seen fit to engage them.

"There's nothing to debunk," says Zdenek P. Bazant, a professor of civil and environmental engineering at Northwestern University and the author of the first peer-reviewed paper on the World Trade Center collapses.

"It's a non-issue," says Sivaraj Shyam-Sunder, a lead investigator for the National Institute of Standards and Technology's study of the collapses.

Ross B. Corotis, a professor of civil engineering at the University of Colorado at Boulder and a member of the editorial board at the journal Structural Safety, says that most engineers are pretty settled on what happened at the World Trade Center. "There's not really disagreement as to what happened for 99 percent of the details," he says.
And one more excerpt on reasons to be skeptical of conspiracy theories in general:
One of the most common intuitive problems people have with conspiracy theories is that they require positing such complicated webs of secret actions. If the twin towers fell in a carefully orchestrated demolition shortly after being hit by planes, who set the charges? Who did the planning? And how could hundreds, if not thousands of people complicit in the murder of their own countrymen keep quiet? Usually, Occam's razor intervenes.

Another common problem with conspiracy theories is that they tend to impute cartoonish motives to "them" — the elites who operate in the shadows. The end result often feels like a heavily plotted movie whose characters do not ring true.

Then there are other cognitive Do Not Enter signs: When history ceases to resemble a train of conflicts and ambiguities and becomes instead a series of disinformation campaigns, you sense that a basic self-correcting mechanism of thought has been disabled. A bridge is out, and paranoia yawns below.
There are a lot of graduate-educated young earth creationists.

Rationalizing Away from the Truth

A big worry that the confirmation and disconfirmation biases raise is the difficulty of figuring out what counts as successful, open-minded reasoning, versus what amounts to after-the-fact rationalization of preexisting beliefs. Here are some links on our tendency to rationalize rather than reason:

More to Forget

Here's more on the less of memory:

Filling in Memory

Here's a section (pages 78-80) from psychologist Dan Gilbert's great book Stumbling on Happiness about how memory works:



The preview cuts off at the bottom of page 80. Here's the rest from that section:
"...reading the words you saw. But in this case, your brain was tricked by the fact that the gist word--the key word, the essential word--was not actually on the list. When your brain rewove the tapestry of your experience, it mistakenly included a word that was implied by the gist but that had not actually appeared, just as volunteers in the previous study mistakenly included a stop sign that was implied by the question they had been asked but that had not actually appeared in the slides they saw.

"This experiment has ben done dozens of times with dozens of different word lists, and these studies have revealed two surprising findings. First, people do not vaguely recall seeing the gist word and they do not simply guess that they saw the gist word. Rather, they vividly remember seeing it and they feel completely confident that it appeared. Second, this phenomenon happens even when people are warned about it beforehand. Knowing that a researcher is trying to trick you into falsely recalling the appearance of a gist word does not stop that false recollection from happening."
Too many words, Sean! Can't you just put up a video? You better make it funny, too!

Fine. Here's Dan Gilbert on The Colbert Report:

Penguin Digestion Experts? You Bet!

So you didn't believe me when I said that there are experts on the subject of penguin digestion? Oh, you did? Fine, well, I'll prove it to you, anyway. Here are some academic articles on the topic:
Of course, no list would be complete without the often-cited, groundbreaking 1985 Ornis Scandinavica article:
Perhaps my favorite, though, is the following:
If any of these articles are above your head (I think they're all above mine!), you might like this, uh, simpler video demonstration of penguin digestion.

An Expert for Every Cause

Looking for links on appealing to authority? This is your post! First, here's an interesting article on a great question: How are non-specialists supposed to figure out the truth about stuff that requires expertise?

Not all alleged experts are actual experts. Here's a method to tell which experts are phonies (this article was originally published in the Chronicle of Higher Education).

It's important to check whether the person making an appeal to authority really knows who the authority is. That's why we should beware of claims that begin with "Studies show..."

And here's a Saturday Night Live sketch in which Christopher Walken completely flunks the competence test.

Paper Guideline

Due Date: the beginning of class on Monday, December 7th, 2009

Worth: 5% of final grade

Length/Format: Papers must be typed, and must be between 300-600 words long. Provide a word count on the first page of the paper. (Most programs like Microsoft Word & WordPerfect have automatic word counts.)

Assignment:
1) Pick an article from a newspaper, magazine, or journal in which an author presents an argument for a particular position. I will also provide some links to potential articles at the course website. You are free to choose any article on any topic you want, but you must show Sean your article by Monday, November 30th, for approval. The main requirement is that the author of the article must be presenting an argument. One place to look for such articles is the Opinion page of a newspaper. Here’s a short list of some other good sources online:
(for even more sources, check out the left-hand column of Arts & Letters Daily)

2) In the essay, first briefly explain the article’s argument in your own words. What is the position that the author is arguing for? What are the reasons the author offers as evidence for her or his conclusion? What type of argument does the author provide? In other words, provide a brief summary of the argument.
NOTE: This part of your paper shouldn’t be very long. I recommend making this about one paragraph of your paper.

3) In the essay, then evaluate the article’s argument. Overall, is this a good or a bad argument? Why or why not? Check each premise: is each premise true? Or is it false? Questionable? (Do research if you have to in order to determine whether the author’s claims are true.) Then check the structure of the argument. Do the premises provide enough rational support for the conclusion? If you are criticizing the article’s argument, be sure to consider potential responses that the author might offer, and explain why these responses don’t work. If you are defending the article’s argument, be sure to consider and respond to objections.
NOTE: This should be the main part of your paper. Focus most of your paper on evaluating the argument.

4) Attach a copy of the article to your paper when you hand it in. (Save trees! Print it on few pages!)

It Tastes Like BurningTIP: It’s easier to write this paper on an article with a BAD argument. Try finding a poorly-reasoned article!
