To shake things up on purpose, hoping the truth settles out on top

means To stir something up—whether a liquid or a crowd—in order to provoke action, change, or reaction.

from From Latin 'agitare,' meaning 'to drive, chase, or keep in motion'—itself a frequentative of 'agere,' 'to do or drive.' So agitate literally means to keep driving something, over and over, until it moves. Latin used it for shaking liquids and harrying armies alike; English kept both senses, letting the word slide easily from a shaken bottle to a shaken society.
