Floresiensis had a total brain volume in the chimp/australopithecus range, yes, but the dorsomedial prefrontal cortex (associated with higher cognition in humans) is about the same size as it is in anatomically-modern homo sapiens. Their habitation sites show all the usual hominin features: fire, bones with cut marks, stone tools of comparable sophistication to contemporary h. sapiens with four times the brain volume—and the prey species associated with the sites, stegodontids, would necessitate cooperative hunts.
