I disagree (in case you meant to imply it) that compression implies generalization.

I did not mean to imply compression implies generalization, if anything the reverse. Compression is the act of cutting, generalization is the whetstone by which you may sharpen a blade, which is the compression heuristic. A more general heuristic is to compression what a sharper blade is to cutting.
