Can You Look at a Sand Castle and Then Build Your Own?

I think that lots of refolders would benefit from engaging in explicit output practice. And I think they'd also benefit from using squigies. My example is recognition with this with a sand castle. So if you're an alien and you've never seen a castle before and I show you a sand castle, you're not going to know what it is. As people, we have a vague idea of what a castle is. But actually producing a sand castle is very hard. We all know what a perfect circle is, but how many of us can draw a perfect circle? Not many.
