Hm. "Don't know something" is not a rigourous state at all. Associations are how we know something; older students have more of them.
Unless they limit themselves to reflex action or some such, it becomes impossible to separate previous learning of anything complex.
I think I give researchers plenty of credit. But they don't often have the time/resources to have many/any controls. When a remarkable correlation appears (like 'students stop learning about when they leave school') I call foul.
