Which one usually min-raised?

If button usually minraised, then SB shows strength and I couldn't run away fast enough. If SB is the one who usually minraises, then button could be trying to steal, and SB probally has a good hand (since even a moron couldn't expect to steal here re-minraising).

I've seen alot of people min-raise to steal (esp with higher blinds), but he could easily be looking for some calls.
