Certainly it's a little misguided to suggest that an OCEAN correlate implies you can train intelligence; OCEAN is relatively stable across your life (that's what makes it a good personality metric). That said, I know at least one person who scored low on O taking an OCEAN battery but is in fact very diligent about seeking out novelty, so I think the O-factor depends more on how enthusiastic you look at the world at large versus deciding you want to be a polymath and working very hard at accomplishing that goal.

On the other hand, being able to have lots of sexual partners implies being able to convince lots of people you're worth having sex with (this is one of the two main goals which developed human intelligence in the first place, the other being killing people who were doing the first too effectively), and taking a lot of psychoactive drugs I think also implies a sort of mental fortitude (it's very difficult to habitually take strong psychedelics without having a solid grasp on reality and how to adjust your actions to account for the change in perspective, the people who can't do this but enjoy psychedelics anyway aren't who anyone is thinking of when they say intelligent people use psychedelics).
