To err is human. To admit to erring… well, that’s difficult. Like most people, I don’t like the feeling of realizing that I’m wrong. I always think I’m right (I can’t help it!), but I don’t think I’m always right. Past experience confirms that I do err; it’s consistent but I can’t predict when it will happen. And I feel I’m right… right up to the moment that I’m proven wrong.
The subject of Wrong-ology is taken up by Kathryn Schulz in her book, Being Wrong. Our minds are funny things and the way we learn and remember things is much more complex and mysterious than we imagine. We think, as Plato suggested, that memory works like a wax tablet: “Everything you experience, from your own thoughts and sensory impressions to interactions with others, creates an imprint in that wax… an unchanging mental replica of the events of the past, captured at the moment they occurred.” This may contribute to that feeling of knowing, even when in gross error.
As a professor, I’m well practiced at professing. Students think you’re more knowledgeable and know what you’re talking about when you present the material confidently. That’s not hard to do because I feel that I know the material. Even when I don’t know it as well as I should, I still present it confidently. Fake it till you make it. Did I do so when I first started teaching? Was I more diffident back then? Honestly, I don’t remember. I’ve learned not to trust my memory even if I feel I can visualize it in my mind’s eye. My spouse provides me a very useful signal when I might be professing with confidence about something I know little about; she says: “You say that so confidently”. That gets me to chuckle, stop, check, and think.
Schulz discusses medical cases of brain issues where patients confidently describe or explain something with no correspondence to actual reality. And they seemingly believe it. This is known as confabulation. Here’s how Schulz describes it: “Imagine, by way of analogy, that each of us possesses an inner writer and an inner fact-checker. As soon as the writer begins devising a story, the fact-checker gets busy comparing it with the input from our senses, checking it against our memory, examining it for internal consistencies, thinking through our database of facts about the world, and, once we utter it, gauging other people’s reactions to assess its credibility… When the fact-checker falls asleep on the job, however, our theories about the world can become wholly unmoored from reality. All of us have experienced this, because the one time our fact-checkers reliably fall asleep is when we do, too. Think about dreams again for a moment, and about how weird even just the averagely weird ones can be… Now, two bizarre things are going on here. The first is that your brain is generating representations of the world that are only lightly tethered to the real, or even to the possible. The second is that you are completely untroubled by this fact.”
Being surprised is a good wake-up call to discovering error. You’d think that by now I would have gotten used to being surprised every time I err. But I am surprised every single time. Consistently, yet unpredictable in when it will happen. I’m heartened when Schulz writes that saying “I don’t know” is a good sign of brain function because in some forms of dementia, the fact-checker falls asleep and confabulation ensues. It also turns out that being confabulatory is part of how the human brain works. It’s an engine, possibly the engine, of creativity and imagination. I can think about and imagine things that are not real. I can make mental models of things that are abstract or invisible (which I must do frequently in thinking about chemistry). Our minds have adapted to come up with quick instinctive solutions, not always thought through, that do serve us well on many an occasion. The feeling of knowing allows us to act quickly when needed.
When grading exams, I still get surprised by the occasional confabulatory explanations of students. A student who has no idea what’s going on is yet able to come up with a fantastical story involving throwing together chemistry concepts completely untethered to reality. It doesn’t happen often, but it’s interesting for me to read these “answers” and try to imagine how a student came up with them. I wonder if that student had the confident feeling of knowing. But actually didn’t. Not knowing what you don’t know isn’t a great situation to be in.
Reading Being Wrong has made me a little quicker to say “I was wrong” in my classes when I make a mistake on the board and it is pointed out by a student. I apologize to the class, then thank the student for paying attention and being brave enough to tell me so that I don’t mislead the class any further. While it doesn’t happen often, I feel that as I age it has ticked up in frequency. I’m not as sharp as I used to be, perhaps. Or maybe I am less well prepared because I’m overconfident in the feeling of knowing, having taught the subject matter multiple times over a couple of decades. But if I actually learn something from my errors, that’s a good thing!
