Question: Were high-domed pachycephalosaurs really head-butting brutes? If not, were they actually intelligent animals like early human species (like Homo erectus), even if their brain cases were small (like how magpies have small brain cases despite being very smart birds), or were their thick cranium used for different purposes?

The behavior and intelligence of pachycephalosaurs, the thick-skulled dinosaurs, is a subject of ongoing research and discussion among paleontologists. While some have speculated that these dinosaurs might have used their uniquely thick skulls for intra-species combat, similar to head-butting in modern animals like goats or bighorn sheep, others suggest different uses for the characteristic anatomy. Recent studies into pachycephalosaur skulls have indicated that they may not have been used for head-butting in the way we once thought. There is not enough evidence of trauma in fossil records to support the head-butting hypothesis extensively. They might have used their thick skulls for flank-butting (striking the sides of adversaries) or display, to deter predators, or to win mates. Regarding the intelligence of pachycephalosaurs, current evidence cannot confidently suggest that they had a level of intelligence similar to early human species like Homo erectus. A creature's intelligence is influenced by many factors, not only the size of the brain in relation to body size, but the complexity of the brain's structure, the animal's behaviors, its environment and evolutionary pressures. It's important to note that some birds like crows and ravens, despite having small brains, exhibit complex problem-solving and social behaviors, which suggests a high level of intelligence. However, there isn't enough evidence to claim similar cognitive abilities for pachycephalosaurs. Furthermore, it's hard to compare the intelligence of dinosaurs to that of primates, such as early hominids. They had very different brain structures, behaviors, and evolutionary pressures. It's likely that pachycephalosaurs had a level of intelligence comparable to modern reptiles or possibly birds, but making more specific comparisons is challenging with the current fossil evidence.
