They are kind of the perfect.
tool of measurement.
Right, a natural experiment, yeah.
To resolve this as much as possible.
So you, you, it's based on the variability, right?
It's the variation.
So if you have a very stable, uh,
non-variable environment.
Most of the observed variability between, say, two twins or two people will be genetically determined.
It's almost like there's a stew and there's
two types of ingredients in the stew.
And like one is genetics and one is environment.
