> Many people talk about forgetting things as soon as the test is over It could be argued that when learning specifically for a test people tend to forget things asap, because things learned this way now carry with them a spirit of something being forced on you.

>but why would they remember it even that long without a test? If you learn something that bores you, sure. But I claim that when you learn not for a test you would properly inspect things and their domains and try to get insights into them, their necessity to the object being studied and so on.
