I would expect people like the people I went to high school with, since that was a pretty random selection of society. That would not be a group where you could describe an abstract concept like the criteria for applying a law and expect them to get it the first time. More likely you'd explain it many times from many different angles over a couple of weeks and then give them a test and they still wouldn't get any part of it entirely correct. And that's on average; you also have the low end of the range, people who managed to put the right words in the right boxes to pass world history but came away not sure if there's an ocean between France and Germany or not. And then at the very bottom there were the ones who couldn't pass high school classes at all....
