Stubborn = Intellectually Dishonest

Here's a little rant on a 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 it's not clear that we're caring 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 it because it's what gets 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 like an arg, but still stubbornly disagree with its conclusion, we are just being irrational.

This means we should be open-minded. We should be willing to let new evidence change our current beliefs. We should be open to the possibility that we might be wrong. This is how Todd Glass puts it:


Here are the first two paragraphs of a great article I read in the Fall 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.

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.

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!

So in the next couple classes, at least, I hope you'll join me in my campaign to end I'M-SPECIAL-ism.
