Do the enemies levels scale in Kingdoms of Amalur: Reckoning?
From what I have read, the enemies do not scale exactly. Each region has a level range for example the first areas are probably like 1-7 or something. If you are in that region and you are over level 7 then the level of the enemies defaults to the highest. Vice verse if you go into an area where the enemies are all red (which will happen, and gives credit to this theory). Then they will default to their lowest level because you aren't close to matching them. I found this on gamefaqs that might also help you understand.
Unfourtunatley I cannot find anything from the game developers themselves to prove this 100% but I believe this is how it works.
However, the simple fact that you can enter regions that have red names (meaning they are too powerful for you) says that enemies can be a higher level which means they don't exactly scale in a 1:1 sense.
