Have you ever used a zipper?

In this study, the researchers asked about a range of stimuli, which in my humble opinion* are really fun to quiz yourself on. Can you explain:
- how a sewing machine works
- how a can opener works
- how a flush toilet operates
- how the heart pumps blood
- how piano keys make soundSome of these are far more elaborate, haha:
- how the aqualung regulates air-pressure
- how a transistor works*granted...I became a psychologist so maybe my sense of fun is warped
@grimalkina reading this post makes me feel like rabbithole georg because I have too many "yes"es
(or at least 'yes' enough that I might be fuzzy on the exact details but can explain the fundamental mechanisms) -
Researchers asked participants to rate their understanding of a political policy, then explain how the policies worked...interestingly, being pushed to produce *mechanistic* (causal) explanations for their views moderated those political views, while merely listing *reasons* for the views didn't
I take away a few implications from this evidence, which falls under the broad area of "metacognition" and belief formation.
- our minds are tremendously adaptive at learning to manipulate things around us, but perfect manipulation and even perfect outcome production isn't always a direct test of understanding. You can have a flawed mental model that still produces a reliable outcome. To study understanding, we need to go deeper.

- if you're interested in becoming an expert -- if you're a student, starting a career, or just picking up a hobby or skill, you might try asking yourself "what are the zippers here." Everyone can use a zipper, but few people can fix broken ones and design unimagined new ones. If you want to become one of those people in an area, find the zippers and learn their mechanisms.

Have you ever used a zipper? Odds are you have. Are you pretty good at it? Odds are! You've probably successfully used a zipper many, many times. You probably can't even remember when and where you learned how to operate a zipper. If you're a good zipper user and we sat you down in a room and gave you ten zippered garments, you'd probably fluently and flawlessly be able to zip them up and down.
Now......can you explain how a zipper works?

- Trying to encourage mechanism thinking can break through extremist belief patterns.
You might have heard "facts don't change minds, feelings do." Well, KIND OF. Facts, feelings and interpretations are actually all deeply intertwined in our processing of the world. It's tempting to think that our minds process and absorb the world like tape recorders. If I list a bunch of reasons why I support a policy, maybe that will convince someone. But dissecting their causal model might work much better.

Metacognition is something I highlight in my book. These are *learnable skills* and they are *very predictive* for real-world outcomes. People who cultivate habits of puncturing cognitive illusions form expertise, and make the people around them better thinkers too.
Amazing how much we can learn just from a little zipper!

@grimalkina As a result of this thread I went on a binge learning about the history of zipper design.
I am now using graphite pencils to properly lubricate all of my zippers, thank you very much.
-
@grimalkina I guess my question would be why?
@CStamp so first, they ask folks to rate how well they understand these things. *then* they asked them to explain how they worked with a causal structure. It's interesting not because of the random items, but because of the differences between what people thought vs the level of understanding they could actually show! So the "why" is "to understand our own minds and their cognitive illusions a little better"

@sidereal TIL!!

@grimalkina This is how I ended up with an enduring Special Interest in tall ships. Innocently asking “how does a square rigger sail upwind at all?” turned into years of learning the next level of detail.

The vast majority of zipper users -- skilled, successful zipper users! -- can't explain how a zipper works.
This is a charming, famous example that comes from cognitive science/psychology work on The Illusion of Explanatory Depth: "Most people feel they understand the world with far greater detail, coherence, and depth than they really do"
Rozenblit, L., & Keil, F. (2002). The misunderstood limits of folk science: An illusion of explanatory depth. Cognitive science, 26(5), 521-562.
@grimalkina It’s funny, I asked out kids - who had never actually though abiut a zipper. I suggested they have a proper look and with a magnifying glass and both of them came upo with the correct solution. Everyday things people tale fopr granted withiout asking how.

Also just as a PS, it's neither possible nor very adaptive to ask yourself to have an overwhelmingly detailed explanation of mechanisms for everything you encounter, so that's not the goal. Groups of people need to fluently work at many different levels of abstraction.
The key is matching the level of understanding to the tasks and problems that we have! And often, coordinating different depths of expertise!
But we can benefit from having metacognitive skills!

@Wen nice, what a great little active learning moment you created!

@grimalkina No you suggested it. I already knew, your postmade me ask them. Thanks.

If I had to explain it to some one without knowing the correct terminology of the components involved.... Probably along the lines of...
Two lines of interlocking prongs that are fed through a small linking device that squeezes the prongs together to lock two sides of an item together. Moving the linking device in the opposite direction, forces the two lines of prongs part once more. At each end of the lines of prongs is a stop to prevent the linking device from falling off.

@grimalkina It's like, I knew graphite was a dry lubricant. But I don't think I would have ever thought to just use a pencil on a zipper. And now I know that I can apply dry lubricant to all kinds of assemblies by just jamming a pencil up in there. Thanks, metacognition!

@sidereal just casually doing learning transfer all over the place
you're killing it -
