[Star Wars] How intelligent is Jabba the Hutt?

More like genius or average or perhaps below average?
gpt
Extremely intelligent. He was around 500 years old and the head of a major Hutt clan with a criminal network that crossed the known galaxy. 

He was a big enough player in the underworld that he could legitimately threaten to put a price on Han's head so high that he "could never go near a civilized system again". The bounty hunter who came after Han at Ord Mantell attempting to make good on that threat spooked him enough to decide to leave the Rebellion and try to compensate Jabba for the spice that he dumped, despite having previously thumbed his nose at Jabba over it back in Episode IV. 

Moreover, in the Clone Wars movie, it's established that Jabba has control over the Hutt Empire's territorial space lanes (or at least has enough influence to grant access to them). This was the reason that both the Republic and the Separatists competed to rescue his son Rotta when he was kidnapped (by Dooku, under Sidious's orders), because Jabba promised to grant free military movement through those lanes to whomever brought him home. 

All in all, Jabba was extremely intelligent. He had to be, in order to run a criminal empire that size. His death was the result of arrogance, not stupidity.
