Even in Scotland only about 50% of people have any decent grasp of Scottish history.
It seems enough for most people to watch Braveheart and be rabid-foaming-at-the-mouth-nationalists with no real idea of WHY they are nationalists.

My wife made a point of studying university level Scottish history while she was studying here and she was horrified when people would tell her that they knew better because they were Scottish.

It's, unfortunately, a fairly common thing. And the clearances and the Union tend to be the two things that people are most-often misinformed about.
