I answered for Range but not for Approval.

Approval is a Range method voted .... Approval style!

Sincere votes under Approval would be any vote that does not reverse 
preferences.

If we consider the underlying preferences and ratings to be 
expressable in Range, then we can consider that the sincere voter 
sets -- or can be seen as setting -- an Approval cutoff rating, and 
all candidates rated above that level are approved and all below it 
are not. Essentially, the voter has divided the candidates into two 
sets, and the vote is sincere if every candidate in the approved set 
is preferred to every candidate in the disapproved set.

There is no known good reason for voting insincerely under Approval. 
It is never forced.
