from When you draw a tree, you mistake one side for a single
Draw a pyramid and you'll think the bottom is bigger.
It's in that form in Constraints by Gravity, but when you use it as a metaphor, there's nothing that corresponds to that constraint.
At first, the language was set to "drawing a tree and mistaking one side for a single" and "drawing a tree or pyramid and mistaking one side for a single", but in the process of fleshing out the details, the two are two different stories.
