Emergentists typically view emergent higher level properties as unpredictable from the smallest constituents of a system and some minimal set of their relations. Which is more or less to say that the h-l property contains more information than its base. So there is little evidence that emergentists are engaging in map-territory confusion, or trying to reify simple h-l properties.
Dualists are not necessarily emergentists.
