1. It is deceptively simple.
2. Deceptively, it is simple.
I believe '1' means something like this: The thing/process etc., seems simple, but that is not so. The apparent is deceptive.
Does '2' mean this: When viewed from a vantage point of deception, the thing seems simple, which it is not.
But if that is the case (in '2'), won't that be more like self-deception than deception?
Can some correct me here, because I am surely missing something crucial here?
